Concrete Patio Repair Solutions

Concrete is heavy, and when the soil supporting it becomes weak, it can crack and sink. Cement patios are often subject to extreme weather, moisture and extra wear and tear, which can lead to cracking, sinking, or more extensive damage, such as cracking, flaking, pitting or crumbling.

Regardless of what’s caused your concrete patio to sink, settle or crack, we can fix it. At Thrasher, we offer a comprehensive concrete protection system. After lifting and leveling your patio with PolyLevel®, we use NexusPro™ to fill and seal cracks and control joints. Then we apply SealantPro™, which permanently bonds with the concrete and protects it from moisture, chemical elements and seasonal changes. For patios with greater damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro™ to give your patio a brand-new look and restore functionality.

Frequently Asked Questions

  •  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.

  • 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.
