Concrete Repair Services

  • Driveways, walkways and sidewalks are exposed to a lot of wear and tear. When the soil supporting it becomes weak or a void is formed, concrete slabs can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or gutter runoff, or a tree root that has rotted over time. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete. 

  • Tearing out and replacing a concrete driveway, sidewalk or patio is a huge undertaking. The old concrete must be jackhammered into manageable pieces and hauled away. Then, new concrete must be poured and left to harden and cure — a process that can take several weeks, during which you’ll have to park on the street and avoid the area. It’s noisy, messy and incredibly disruptive. On the other hand, concrete repair and resurfacing is a quick, easy process that requires minimal disruption, yet offers the same look and functionality of total concrete replacement. Unlike brand new concrete, it can be ready for use the very next day. Learn more about lifting and leveling concrete with PolyLevel here, or concrete resurfacing with our ResurfacePro system here. 

  • Yes. Concrete leveling with PolyLevel is not only less expensive than full concrete replacement, it’s also a much quicker repair process and far less disruptive to the surrounding grass and landscaping. There’s almost no wait time for the concrete to cure before you can walk or drive on it, and unlike concrete replacement, PolyLevel actually fills voids and compacts underlying soil, which stabilizes your concrete for years to come. 

  • Most concrete leveling and repair projects take our crews a single day to complete, and Polylevel cures quickly, allowing your concrete to be used normally the same day. Alternate solutions like mudjacking or concrete replacement often require more time and disruption, as well as longer cure times, which could mean parking on the street or avoiding your sidewalk or front steps. 

  • Your concrete most likely didn’t settle, but instead the adjacent concrete slabs heaved upwards, due to the frozen dirt below. There is nothing that can be done, but wait for the ground to thaw and the concrete to return to its original position. If the concrete doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary.

  • If your concrete has shifted up during the winter months, it is most likely heave from the frozen dirt below the concrete. This is normal, and usually the concrete will return to normal once the ground thaws. If it doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary. 

Caulking Repair

  • We use NexusPro joint sealant for concrete caulking projects of all sizes. We use it to fill and seal small cracks and control joints, and it’s also part of our comprehensive concrete protection system and ResurfacePro system, which addresses problems like concrete pitting, flaking and crumbling.

  • We use NexusPro silicone-based sealant to fill and seal cracks and control joints after lifting and leveling the concrete steps with PolyLevel. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products, and it’s been proven to last more than twice as long.

  • Yes. NexusPro is part of our comprehensive concrete protection system. First, your concrete is lifted and leveled using PolyLevel polyurethane foam. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. Finally, the whole surface is protected from the elements with a coat of SealantPro concrete sealant, which permanently bonds to your concrete. 

  • We can repair small and mid-size cracks with NexusPro silicone-based caulking sealant. During installation, we prepare and clean the concrete cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. 

  • Concrete leveling with PolyLevel followed by concrete caulking with NexusPro is not only less expensive than full concrete replacement, it’s also a much quicker repair process and far less disruptive to the surrounding grass and landscaping. There’s almost no wait time for the concrete to cure before you can walk on it, and unlike concrete replacement, PolyLevel actually fills voids and compacts underlying soil, which stabilizes your concrete for years to come. NexusPro concrete caulking seals cracks and joints to protect from future soil erosion, and it resists UV rays, which means it won’t crack, bubble or dry out. 

  • Yes. All cracks and joints in your driveway, including concrete expansion joints, should be caulked and sealed to prevent water intrusion which leads to soil erosion. 

Concrete Joint Caulking & Repair

  • Concrete expansion joints are necessary to allow the concrete slabs that make up your driveway to shift and move inward over time. This prevents cracking, buckling and heaving to prolong the life of your driveway.

  • When concrete expansion joints aren’t sealed properly, moisture can seep beneath your driveway, which can cause the underlying soil to soften or even wash away completely. That in turn can cause the concrete slab to crack further as it sinks into the void left by the washed-away soil. This is why proper concrete joint caulking is so important.

  • We use NexusPro silicone-based sealant to seal control joints, often after lifting and leveling the concrete with PolyLevel. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products, and it’s been proven to last more than twice as long.

  • Most urethane caulking products take anywhere from 24 to 72 hours to cure. NexusPro silicone-based sealant has a tack-free time of four hours, and won’t crack, bubble or dry out over time.  

  • When we install NexusPro, we prepare and clean the concrete joints, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products.

  • You can buy polyurethane caulk at your local big-box DIY store, so you might be tempted to caulk your concrete expansion joint yourself. But polyurethane caulks can bubble, dry out and crack when exposed to the sun and elements over time. At Thrasher, we use a silicone-based crack and joint sealer developed by our sister company, Supportworks. It’s called NexusPro, and it offers a long-lasting and durable solution that will keep moisture from seeping beneath your concrete, where it can cause further problems. When we install NexusPro, we prepare and clean the concrete joints, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. That’s something you won’t get from the big-box store.

Concrete Crack Caulking & Repair

  • We use NexusPro silicone-based sealant to fill and seal cracks and control joints after lifting and leveling the concrete steps with PolyLevel. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products, and it’s been proven to last more than twice as long.

  • In short, it depends. While small cracks in your concrete can likely be patched with a sidewalk crack filler from your local big box store, this won’t fix the underlying settlement problem and more cracks can form in your sidewalk. Do-it-yourself repairs might be less expensive, but they are messy, require special tools and equipment, and it can be as long as 30 days before you’re able to apply significant weight to it again (like your car, for example).

  • Concrete caulking repairs are part of maintaining your concrete surfaces and help prolong the life of your concrete driveway, sidewalk or patio. NexusPro is often installed as part of our comprehensive concrete protection system, which comes with a 5-year warranty and has been proven to last over 20 years. 

  • When concrete cracks turn to pitting, crumbling or flaking concrete, caulking may not be enough to repair the surface damage. Instead, we typically recommend our ResurfacePro system, which coats your broken and unsightly concrete surfaces with a durable layer of polymer cement. This process gives your concrete a brand-new look and restores its function.

  • All cracks and joints in your driveway, including concrete expansion joints, should be caulked and sealed to prevent water intrusion which leads to soil erosion. 

  • Yes. We use NexusPro silicone-based sealant to repair and seal concrete cracks, as well as to seal control joints after lifting and leveling the concrete with PolyLevel.

  • There are several factors that influence the cost for repairing concrete cracks with caulking, including the extent of the damage and the method of repair. When we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the solution we propose to repair your concrete cracks and why. You’ll receive a same-day, no obligation estimate for repair, which is calculated by our custom software to ensure a fair and accurate price for every homeowner. You’ll also receive a copy of our warranty so you know what’s covered and for how long.

Concrete Leveling & Repair

  • Almost any concrete slab that sits on top of soil can be lifted and leveled with PolyLevel. This includes traditional areas - concrete driveways, sidewalks, patios - as well as other concrete areas around your home or office, such as your pool deck or front stoop.

  • PolyLevel polyurethane foam is pumped beneath concrete slabs through tiny ports about the size of a penny. Initially, PolyLevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the concrete slabs above it and compressing the soil around it at the same time. PolyLevel cures quickly, allowing your concrete to be used normally just 15 minutes after installation.

  • At Thrasher, we use PolyLevel polyurethane foam to lift and level concrete. PolyLevel is a lightweight, strong high-density polyurethane foam that lifts and supports concrete slabs without adding weight to the soil beneath. It’s waterproof, so it won’t wash out or dry out like traditional mudjacking material. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete leveling with PolyLevel expanding foam not only raises concrete slabs, but also compacts the soil around it, creating a stable environment that will ensure that your driveway, patio or pool deck remains level into the foreseeable future.

  •  Driveways, walkways and sidewalks are exposed to a lot of wear and tear. When the soil supporting it becomes weak or a void is formed, concrete slabs can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or gutter runoff, or a tree root that has rotted over time. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete.

  • It depends on the concrete repair method you choose. Concrete leveling with PolyLevel is the quickest and most efficient route. Most concrete leveling and repair projects take our crews a single day to complete, and PolyLevel cures quickly, allowing your concrete to be used normally the same day. Alternate solutions like mudjacking or concrete replacement often require more time and disruption, as well as longer cure times which could mean parking on the street or avoiding your sidewalk or front steps.

  • Uneven concrete is extremely common due to wear and tear and changing weather patterns which affect the soils below. In some cases, the damage is cosmetic only; in others it may pose a tripping hazard or trouble pulling into your garage. The most serious concrete leveling problems that we find are those that impact surrounding structures - in most cases, your home. A sinking concrete driveway near your garage can lead to foundation cracks and expensive damage over time.

  • After lifting and leveling your concrete patio with PolyLevel, our crews fill and seal any cracks as well as control joints. This prevents water infiltration, which in turn helps prevent the soil below from softening and eroding over time. We use a high quality, silicone-based sealant called NexusPro. It’s specially engineered to stand up to harsh weather conditions, and unlike traditional urethane sealants, it is UV-resistant to prevent drying, cracking, bubbling or yellowing. 

  • Yes, we use PolyLevel® polyurethane foam to lift and level cement patios. Polylevel is a lightweight, strong high-density polyurethane foam developed by our sister company Supportworks and only available to an exclusive network of foundation and concrete repair contractors. It lifts and supports cement slabs without adding weight to the soil beneath, and it’s waterproof, so it won’t wash out or dry out like traditional mudjacking material. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete patio leveling with PolyLevel expanding foam not only raises concrete slabs, but also compacts the soil around it, creating a stable environment that will ensure that your patio remains level into the foreseeable future.

  • Most concrete patio leveling and repair projects take our crews a single day (or less!) to complete, and Polylevel cures quickly, allowing your concrete to be used normally just 15 minutes after installation. Alternate solutions like mudjacking or concrete replacement often require more time and disruption to the surrounding landscaping, as well as longer cure times which could mean avoiding your patio for several days or weeks.

  • With our comprehensive concrete protection system plus our new resurfacing process, ResurfacePro, it’s rare that we come across a patio that can’t be repaired. For small and mid-size concrete cracks, we use NexusPro to fill and seal cracks and control joints after lifting and leveling the concrete patio with PolyLevel. For patios with more significant damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro to give a brand-new look and restore functionality. If you suspect that your cracked concrete patio is beyond repair, it’s worth having a professional inspection to find out if it’s eligible for resurfacing, and compare the cost and benefits of repair vs. full concrete patio replacement. 

  • In many cases, yes. We can lift and level almost any concrete slab, regardless of surface texture.

Concrete Sidewalk Repair & Leveling

  • With our comprehensive concrete protection system plus our resurfacing system, ResurfacePro, it’s rare that we come across a sidewalk that can’t be repaired. For small and mid-size sidewalk cracks, we use NexusPro to fill and seal cracks and control joints after lifting and leveling the sidewalk slabs with PolyLevel. For sidewalks with greater damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro to give a brand-new look and restore functionality. If you suspect that your cracked concrete sidewalk is beyond repair, it’s worth having a professional inspection to find out if it’s eligible for resurfacing, and compare the cost and benefits of repair vs. full concrete replacement.

  • Yes. Concrete sidewalk leveling with PolyLevel is not only less expensive than full concrete replacement, it’s also a much quicker repair process and far less disruptive to the surrounding grass and landscaping. There’s almost no waiting for the concrete to cure before you can walk on it, and unlike concrete replacement, PolyLevel actually fills voids and compacts underlying soil, which stabilizes your concrete for years to come.

  • Polylevel polyurethane foam is pumped beneath concrete sidewalk slabs through tiny ports about the size of a penny. Initially, Polylevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the concrete slabs above it and compressing the soil around it at the same time. Polylevel is waterproof, so it will never wash out, and it won’t degrade over time due to temperature extremes. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Best of all, Polylevel cures quickly, allowing your concrete to be used normally the same day.

  • There are several differences between PolyLevel and mudjacking - the material used, the installation process, and of course, the results. Mudjacking material is made up of a mud-cement-slurry mixture while PolyLevel is a lightweight, strong high-density polyurethane foam. Mudjacking requires a messy, disruptive installation process and larger port size than PolyLevel polyurethane foam. And finally, mudjacking doesn’t address the underlying issue (stability) as well as PolyLevel does. Concrete sidewalks sink and crack due to the soil below expanding, contracting, washing out and leaving voids into which the heavy concrete slabs sink. Mudjacking material is heavy, adding more weight on top of the already unstable soil, and is susceptible to the same issues of wash out and void creation. PolyLevel is waterproof, so it won’t wash away or degrade over time. During installation, the expanding foam not only raises concrete slabs, but also compacts the soil around it, adding stability to help prevent future sinking and settling. You can read more about PolyLevel vs. mudjacking here on our blog. 

  • The key to any sidewalk crack filler project is how it’s sealed after being filled. Concrete sealant prevents water infiltration through cracks and joints, which in turn helps prevent the soil below from softening and eroding over time. Our high quality, silicone-based sealant, NexusPro, and professional installation process have been proven to last over 20 years - more than twice as long as traditional urethane-based sealants. NexusPro stands up to any weather conditions and is UV-resistant to prevent drying, cracking, bubbling or yellowing.

  • At Thrasher Foundation Repair, we use PolyLevel polyurethane foam to lift and level sidewalks and walkways. Polylevel is a lightweight, strong high-density polyurethane foam developed by our sister company Supportworks and only available to an exclusive network of foundation and concrete repair contractors. It lifts and supports concrete sidewalk slabs without adding weight to the soil beneath, and it’s waterproof, so it won’t wash out or dry out like traditional mudjacking material. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete leveling with PolyLevel expanding foam not only raises concrete slabs, but also compacts the soil around it, creating a stable environment that will ensure that your sidewalk remains level into the foreseeable future.

  • Uneven or raised sidewalk slabs are very common, as the soil beneath shifts and erodes over time. The moisture level in the soil beneath your sidewalk can vary depending on nearby gutter downspouts, varying dirt fill compact, and natural weather patterns. This means your sidewalk slabs may shift and settle at varying rates, causing some slabs to raise while others sink. We repair a raised sidewalk by lifting the surrounding concrete slabs to create an even and level surface. Then, we seal the entire surface to keep water out and help prevent the problem from happening again in the future. 

  • In short, it depends. While small cracks in your concrete can likely be patched with a sidewalk crack filler from your local big box store, this won’t fix the underlying settlement problem and more cracks can form in your sidewalk. Do-it-yourself repairs might be less expensive, but they are messy, require special tools and equipment, and it can be as long as 30 days before you’re able to apply significant weight to it again (like your car, for example).

Concrete Driveway Repair & Leveling

  • Concrete is a strong, durable material, but it’s only as stable as the soil that it sits on top of. Over time, the soil below your concrete driveway can degrade or wash away due to several factors, including rain, drought or simply the fact that the fill soil deposited there when your home was built wasn’t compacted well. When this happens, the concrete driveway above eventually cracks and sinks into the voids.  

  • PolyLevel is a lightweight, strong high-density polyurethane foam, developed by our sister company Supportworks and only available to an exclusive network of foundation and concrete repair contractors. A more recent technology than mudjacking, PolyLevel utilizes polyurethane foam rather than a mud-cement-slurry mixture to lift and level uneven concrete driveways. Mudjacking requires a messy, disruptive installation process and larger port size than PolyLevel polyurethane foam. Additionally, mudjacking doesn’t address the underlying issue (stability) as well as PolyLevel does. Concrete driveways sink and crack due to the soil below expanding, contracting, washing out and leaving voids into which heavy concrete slabs sink. Mudjacking material is heavy, adding more weight on top of the already unstable soil, and is susceptible to the same issues of wash out and void creation.

  • Most driveway leveling and repair projects take our crews a single day to complete, and Polylevel cures quickly, allowing your concrete to be driven and walked on just 15 minutes after installation. Alternate solutions like mudjacking or concrete replacement often require more time and disruption, as well as longer cure times which could mean parking on the street and avoiding your garage for several days.

  • The need to resurface your concrete driveway is typically dependent on the amount and severity of surface damage. Small and mid-size driveway cracks can be filled and sealed after lifting and leveling the driveway with PolyLevel. However, driveways with a large number of cracks or flaking, pitting or crumbling concrete, we use ResurfacePro to give a brand-new look and restore functionality. If you suspect that your cracked concrete driveway is beyond repair, it’s worth having a professional inspection and comparing the cost and benefits of repair and resurfacing vs. fully replacing your driveway.

  • Repairing your concrete driveway cracks with PolyLevel is not only less expensive than full concrete replacement, it’s also a much quicker repair process and far less disruptive to the surrounding grass and landscaping.

Concrete Step Repair & Leveling

  • Small and mid-size cracks in your concrete steps can be filled and sealed after lifting and leveling the driveway with PolyLevel. For concrete steps with greater damage – including flaking, pitting or crumbling concrete – we use ResurfacePro to give a brand-new look and restore functionality. The ResurfacePro system coats broken and unsightly concrete steps with a durable layer of polymer cement, giving it a brand-new look and restoring its function.

  • Most concrete step leveling and repair projects take our crews a single day to complete, and Polylevel cures quickly, allowing your concrete to be used normally just 15 minutes after installation. Alternate solutions like mudjacking or concrete replacement often require more time and disruption, as well as longer cure times which could mean parking on the street and avoiding your garage for several days.

  • Front stoops and concrete steps often sink and settle over time. Extreme weather and wear and tear can cause additional damage, such as cracking, flaking, pitting or crumbling. All of this can be repaired with our suite of concrete repair products. For sinking concrete steps with small and mid-size cracks, we use NexusPro to fill and seal cracks after lifting and leveling the concrete steps with PolyLevel. For concrete steps with greater damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro to give a brand-new look and restore functionality.

  • After lifting and leveling your concrete stairs with PolyLevel, our crews fill and seal any cracks or joints. This prevents water infiltration through cracks and joints, which in turn helps prevent the soil below your concrete stairs from softening and eroding over time. We use a high quality, silicone-based sealant called NexusPro. It’s specially engineered to stand up to harsh weather conditions, and unlike traditional urethane sealants, it is UV-resistant to prevent drying, cracking, bubbling or yellowing.

Concrete Floor Repair & Leveling

  • Basement floor cracks are normal and in many cases don’t need to be repaired. Cracks with heaving, gaps greater than 1/8” or wall-floor joint cracks can signal a larger foundation problem, or can let water, moisture, and dangerous soil gasses into your home, and should be inspected by a professional to determine if repair or sealing is necessary.

  • In many cases, basement floor cracks are caused by normal settlement or concrete shrinkage and not cause for concern. Larger cracks or gaps between the floor and foundation wall can let in water and moisture which can lead to foundation problems or basement water intrusion over time. Cracks combined with heaving is a signal that the soil beneath the basement floor is expanding, which can also lead to foundation problems or significant basement floor damage. If you notice large or growing basement floor cracks, it’s a good idea to have a professional foundation repair contractor out to inspect and recommend the best solution.

  • In many cases, basement floor cracks can be repaired by filling and sealing to prevent water intrusion. Our experts provide a thorough inspection to determine if the basement floor cracks are a signal of a larger foundation issue and if so, will recommend the best solution for repair.

  • Since masonry is more likely to break than bend, concrete floors that are uneven are generally cracked and/or broken as well. If your foundation is settling, it may be lifting the concrete floor as the rest of the foundation experiences movement. There are also times where the slab floor can lift or sink independently of the walls. Concrete slab floors crack and settle when the soils underneath them shrink, settle or wash away. Likewise, a concrete slab will lift, or “heave”, when the soils underneath expand.

  • At Thrasher, we use PolyLevel® for concrete floor leveling because it’s a fast and effective way to lift and stabilize sinking concrete. Polylevel polyurethane foam is pumped beneath concrete slabs through tiny ports about the size of a penny. Initially, Polylevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the concrete slabs above it and compressing the soil around it at the same time.

  • In addition to lifting, leveling and repairing concrete floor cracks, we also offer resurfacing for concrete floors with greater damage, such as flaking, pitting or crumbling. We use ResurfacePro to give a brand-new look and restore functionality.

  • Yes. In fact, it’s always a good idea to have your basement and foundation inspected and repaired before finishing the space, rather than finding issues down the road and having to rip out and refinish to accommodate necessary repairs.

Concrete Garage Repair & Leveling

  • Concrete can crack over time, often early on in its lifespan as it cures and shrinks. Short hairline cracks in your garage floor are usually nothing to worry about, but can be repaired or refinished for a brand-new look. Larger garage floor cracks or heaving can be a signal that the soil below is expanding, often due to moisture.

  • Short hairline cracks in your garage floor are normal and usually don’t require repair. However, larger cracks, heaving, or gaps between the floor and wall can signal a larger foundation problem. If you notice larger cracks or they appear to be growing, it’s a good idea to have a professional foundation repair inspection and fix the problem early before it causes additional damage. 

  • Pitting, cracking and crumbling can be caused by the harsh chemicals for snow removal. Snow build up on the underside of your vehicle then melts on the garage floor resulting in water. The freeze/thaw cycle over time causes the pitting and crumbling.  Sealing your garage floor with a high quality sealant can prevent pitting.  Thrasher uses SealantPro™ which permanently protects your garage floor.

  • At Thrasher, we use NexusPro, a silicone-based crack and joint sealer developed by our sister company Supportworks, for concrete crack repair and control joint sealing. NexusPro offers a long-lasting and durable solution that will keep moisture from seeping beneath your concrete garage floor, where it can cause further problems. When we install NexusPro, we prepare and clean the garage floor cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. 

  • At Thrasher, we use PolyLevel polyurethane foam to lift and level garage floors. PolyLevel is a lightweight, strong high-density polyurethane foam that lifts and supports concrete without adding weight to the soil beneath. It’s waterproof, so it won’t wash out or dry out like traditional mudjacking material. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete leveling with PolyLevel expanding foam not only raises your garage floor back to level, but also compacts the soil around it, creating a stable environment that will ensure your garage floor remains level into the foreseeable future.

  • We resurface damaged garage floors with our ResurfacePro system, which coats your broken and unsightly concrete surfaces with a durable layer of polymer cement. This process gives your garage floor a brand-new look and restores its function — and it can be ready for use in just a couple days.

  • Yes, we can lift, level and repair epoxied or coated concrete garage floors. Depending on the exact finish and look of your garage floor, our design specialist will recommend the best solution to address the underlying problem while considering aesthetic results as well. 

Concrete HVAC Pad Repair & Leveling

  • An uneven HVAC concrete pad can strain the copper coolant tubes and electrical lines or allow for water pooling around the unit. Without repair, an unlevel HVAC concrete pad can cause damage to your HVAC unit, requiring expensive repair and replacement costs. 

  • HVAC concrete pads hold a lot of weight and are exposed to moisture and changing weather patterns. When the soil supporting it becomes weak or a void is formed, concrete pads can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or gutter runoff, or a tree root that has rotted over time. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete. 

  • Yes. We can lift and level your sinking concrete HVAC pad back to its original position with PolyLevel polyurethane foam. Concrete leveling with PolyLevel expanding foam not only raises your cement HVAC pad, but also compacts the soil around it, creating a stable environment that will ensure your HVAC unit remains level into the foreseeable future.

  • Most concrete HVAC pad leveling and repair projects take our crews a single day to complete, and Polylevel cures quickly, allowing your concrete to be used normally the same day. Alternate solutions like concrete replacement often require more time and disruption, as well as longer cure times.

Cracked Concrete Repair

  • Cracked and uneven concrete that remains unrepaired will only get worse over time. In the short term, sunken or heaved concrete slabs present tripping hazards that you may be liable for as a homeowner. In the long term, without repair and proper sealing, the concrete will continue to crack and crumble, eventually requiring replacement. Properly maintaining your concrete by repairing and sealing cracks will extend the life of your concrete for years to come. 

  • When it comes to foundation crack repair, there are several factors we consider before proposing a solution, such as the location and size of the foundation cracks. At Thrasher, we’re experts in both foundation repair and concrete repair and maintenance. So, when we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the foundation crack repair solution we propose and why. 

  • NexusPro is a silicone-based sealant for joints and cracks specially engineered to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products.

  • If the cement is sinking or unlevel, we use PolyLevel® polyurethane foam to lift and level the concrete. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. When we install NexusPro, we prepare and clean the concrete cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. Finally, the whole surface is protected from the elements with a coat of SealantPro™, which permanently bonds to your concrete. 

  • Foundation wall cracks and the impending structural damage is caused by the soil surrounding your home. When the soil absorbs water during wet, rainy seasons, it expands. Conversely, the soil will shrink during dry seasons and droughts. This pattern of expansion and contraction puts enormous pressure on the foundation walls, and can cause the foundation to crack, heave and shift. Poured basement walls typically fail from the top corners inward, resulting in longer diagonal cracks that emanate from the corners of the foundation wall. Block foundation walls most often fail horizontally in the middle, bowing in as the mortar joints break. The evidence of a failing foundation block wall, then, will usually consist of horizontal foundation wall cracks midway up a basement wall. You may also see stairstep cracks as the joints fail around concrete blocks at different levels. If you do see foundation wall cracks of this type, don’t panic — most foundations can be stabilized and even lifted back to their original position using specialized equipment. This is often less expensive and far less disruptive than total foundation repair.

  • Concrete can crack over time, often early on in its lifespan as it cures and shrinks. So, if you find a short, often vertical, hairline crack in your foundation wall — especially if it occurs near the seam where the forms were joined for the initial foundation pour — it may be nothing to worry about. However, foundation wall cracks can also be a sign of structural damage caused by the expansion and contraction of the soil surrounding your home. The pressure from expanding soils can cause your foundation to crack, heave and shift. Foundation cracks that are caused by settlement are very serious and will only get worse over time as the home continues to move.

  • When we visit your home for the first time, we’ll perform a thorough inspection and you’ll receive a thorough explanation of the concrete repair solution we propose and why. If the concrete is sinking or unlevel, we use PolyLevel polyurethane foam to lift and level the concrete. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. Finally, the whole surface is protected from the elements with a coat of SealantPro, which permanently bonds to your concrete. 

Concrete Pool Repair & Leveling

  • After lifting and leveling your concrete pool deck with PolyLevel, our crews fill and seal all cracks and control joints. This prevents water infiltration, which in turn helps prevent the soil below from softening and eroding over time. This is especially important for pool decks as they are exposed to extra moisture and wear and tear. We use a high quality, silicone-based sealant called NexusPro. It’s specially engineered to stand up to harsh weather conditions, and unlike traditional urethane sealants, it is UV-resistant to prevent drying, cracking, bubbling or yellowing. 

  • At Thrasher, we use PolyLevel for concrete pool deck leveling because it’s a fast and effective way to lift and stabilize sinking pool decks. We also have solutions to repair cracks, seal the surface to prevent water intrusion, or even resurface your pool deck for a brand-new concrete look. 

  • Pool decks are exposed to a lot of wear and tear. When the soil supporting it becomes weak or a void is formed, concrete slabs can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or pool water, or a tree root that has rotted over time. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete. 

  • In many cases, yes. We can lift and level almost any concrete slab, regardless of surface texture.

  • At Thrasher, we use PolyLevel for cement pool deck leveling because it’s a fast and effective way to lift and stabilize sinking concrete. PolyLevel polyurethane foam is pumped beneath the concrete pool deck slabs through tiny ports about the size of a penny. Initially, PolyLevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the pool deck above it and compressing the soil around it at the same time. PolyLevel is waterproof, so it will never wash out, and it won’t degrade over time due to temperature extremes. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Best of all, PolyLevel cures quickly, allowing your pool deck to be used normally the same day.

  • Most concrete pool deck leveling and repair projects take our crews a single day to complete, and Polylevel cures quickly, allowing your concrete to be used normally just 15 minutes after installation. Alternate solutions like mudjacking often require more time and disruption, as well as longer cure times which could mean avoiding your pool for several days.

Concrete Porch Repair & Leveling

  • At Thrasher, we use PolyLevel for concrete porch leveling because it’s a fast and effective way to lift and stabilize sinking concrete. PolyLevel polyurethane foam is pumped beneath the concrete porch slabs through tiny ports about the size of a penny. Initially, PolyLevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the concrete slabs above it and compressing the soil around it at the same time. PolyLevel is waterproof, so it will never wash out, and it won’t degrade over time due to temperature extremes. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Best of all, PolyLevel cures quickly, allowing your porch to be used normally the same day.

  • Front stoops and cement porches often sink and crack over time. Extreme weather and wear and tear can cause additional damage, such as cracking, flaking, pitting or crumbling. All of this can be repaired with our suite of concrete repair products. For sinking cement porches with small and mid-size cracks, we use NexusPro to fill and seal cracks after lifting and leveling the concrete porch with PolyLevel. For cement porches with greater damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro to give a brand-new look and restore functionality. 

  • After lifting and leveling your concrete porch with PolyLevel, our crews fill and seal any cracks as well as control joints. This prevents water infiltration through cracks and joints, which in turn helps prevent the soil below from softening and eroding over time. We use a high quality, silicone-based sealant called NexusPro. It’s specially engineered to stand up to harsh weather conditions, and unlike traditional urethane sealants, it is UV-resistant to prevent drying, cracking, bubbling or yellowing.

  • In most cases, yes. Concrete porches with significant damage, such as flaking, pitting or crumbling concrete can be repaired and resurfaced with ResurfacePro to give a brand-new look and restore functionality. If you suspect that your concrete porch is beyond repair, it’s worth having a professional inspection to find out if it’s eligible for resurfacing, and compare the cost and benefits of repair vs. full concrete replacement.

  • It depends on the method of repair. Most of our concrete porch repair projects come with a five-year warranty and have been proven to last over 20 years. Concrete leveling with PolyLevel expanding foam not only raises concrete porch slabs, but also compacts the soil around it, creating a stable environment that will ensure that your porch remains level into the foreseeable future. Plus, after lifting and leveling your concrete with PolyLevel, we use a high quality, silicone-based concrete sealant on all cracks and control joints to prevent water infiltration, which adds another layer of protection to prevent the soil below from softening and eroding over time. NexusPro stands up to any weather conditions and is UV-resistant to prevent drying, cracking, bubbling or yellowing.

  • Thrasher does not provide regular maintenance on concrete repair services, but we do recommend that the homeowner take the following steps for to maintain and extend the life of all concrete surfaces:

    • Maintain pliable and intact sealant in joints and cracks of the concrete.
    • Keep downspouts connected, and ensure water flows away from your porch and other concrete surfaces. 
    • Ensure sprinkler lines are properly maintained and not over saturating the area near concrete.

    After you’ve had your concrete porch repaired, you may still notice your concrete shift upwards during the winter months due to heave from the frozen dirt below the concrete. This is normal, and usually the concrete will return to normal once the ground thaws. 

  • There are several factors that influence the cost for concrete porch repair, including the extent of the damage and the method of repair. When we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the solution we propose to repair your concrete porch and why. You’ll receive a same-day, no obligation estimate for repair, which is calculated by our custom software to ensure a fair and accurate price for every homeowner. You’ll also receive a copy of our warranty so you know what’s covered and for how long.

Concrete Sealing

  • Almost any concrete surface can be sealed, and any concrete that is exposed to wear and tear and natural elements will benefit from concrete sealing. Concrete sealing protects concrete surfaces from moisture, chemical elements and seasonal changes, which helps to prevent pitting, flaking and cracking. 

  • If your concrete is in need of lifting, leveling or crack repair, we complete these repairs first. Then we apply SealantPro, which permanently bonds with the concrete and protects it from moisture, chemical elements and seasonal changes. It dries and cures quickly, allowing for regular use of your concrete driveway, sidewalk or patio within hours. 

  • At Thrasher, we use SealantPro concrete sealant for concrete sealing projects. It permanently protects concrete with just one application, extending its life by 3-5 times. It’s stain-resistant and UV-resistant, so it won’t discolor over time. 

  • Driveways, walkways and sidewalks are exposed to a lot of wear and tear. When the soil supporting it becomes weak or a void is formed, concrete slabs can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or gutter runoff, or a tree root that has rotted over time. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete.

  • Most concrete sealing projects take our crews a single day to complete, and SealantPro dries and cures quickly, allowing your concrete to be used normally within hours.

  • Uneven concrete is extremely common due to wear and tear and changing weather patterns which affect the soils below. In some cases, the damage is cosmetic only; in others it may pose a tripping hazard or trouble pulling into your garage. The most serious concrete leveling problems that we find are those that impact surrounding structures - in most cases, your home. A sinking concrete driveway near your garage can lead to foundation cracks and expensive damage over time.

Concrete Resurfacing

  • All of our concrete resurfacing projects come with a five-year warranty and have been proven to last over 20 years. ResurfacePro™ is actually a comprehensive concrete protection system which includes concrete lifting and leveling with PolyLevel expanding foam and concrete sealing with NexusPro joint sealant and SealantPro concrete sealer to protect from the elements. The entire process not only raises and protects your concrete from future water intrusion but also compacts the soil around it, creating a stable environment that will ensure that your concrete remains level into the foreseeable future.

  • Concrete with surface damage, such as flaking, pitting or crumbling concrete - in other words, concrete that looks like it might need replaced - may be repaired and renewed with ResurfacePro. The ResurfacePro concrete resurfacing system coats broken and unsightly concrete steps with a durable layer of polymer cement, giving it a brand-new look and restoring its function. If you suspect that your cracked concrete sidewalk is beyond repair, it’s worth having a professional inspection to find out if it’s eligible for resurfacing, and compare the cost and benefits of repair vs. full concrete replacement. 

  • For concrete resurfacing, we use ResurfacePro, which coats your broken and unsightly concrete surfaces with a durable layer of polymer cement, giving it a brand-new look and restoring its function — and it can be ready for use in just a couple days.

  • ResurfacePro is actually a comprehensive concrete protection system consisting of several important steps. First, your concrete is lifted and leveled using PolyLevel® polyurethane foam. Then, your cracked concrete is repaired and sealed. Next, your driveway, patio, sidewalk or pool deck is completely resurfaced with the ResurfacePro material. Then, the control joints are filled and sealed using NexusPro™ joint sealant. Finally, the whole surface is protected from the elements with a coat of SealantPro™ concrete sealer.

  • Cracked, broken and pitted concrete driveways, sidewalks and patios are more than just an eyesore — they lower the value of your home. Concrete replacement can be expensive and extremely disruptive, plus, it doesn’t address the root of the problem. With ResurfacePro, you’ll get the brand-new concrete look while adding stability to prevent future sinking and settlement.
