Concrete repair & concrete leveling experts in Kansas City

Kansas City's ever-changing climate can weaken your slabs, causing the load-bearing soils to contract, dry out, or even wash away. This means without sufficient support, the slab will start to sink and crack. The changes in temperature and moisture can also cause concrete to crack, flake, and stain. So if you’re tired of sinking, cracked driveways, pool decks, sidewalks, or other concrete slabs around your property, contact the concrete repair professionals at Thrasher Foundation Repair.

We offer simple, innovative solutions that are far superior to the standard mudjacking or concrete replacement. Plus, our solutions last all year round, withstanding harsh weather, extreme temperatures, chemicals, UV rays, liquid, debris, and more.

Our cracked concrete repair, concrete leveling, and concrete sealing systems install with no mess and no stress. Plus, they are quick to cure, so you can use your slabs soon after installation.

Durable foundation repairs in Kansas City

Kansas City is known for its extreme weather fluctuations – and as stressful as it can be to prepare your family for the hot summers and icy winters, the foundation can be negatively impacted if not protected as well.

As the temperature and weather patterns change, this can cause the soil around the foundation to expand from moisture and freezing and contract when it is hot and dry. This can lead to foundation settlement, cracks from pressure, bowing walls, and other foundation problems. The high temperatures and lack of rain can also dry out the foundation, which can weaken the structure, cause cracks, and leaks.

But there is no reason to worry. Unlike other contractors, Thrasher Foundation Repair does not provide one-size-fits-all solutions. We understand that every home is different and depending on where you live in Kansas City, your problems may need a more personal touch. In fact, we have been providing customizable and permanent foundation repair solutions to homeowners since 1975. So no matter how serious the foundation damage may seem, you can trust us to provide repairs tailored to your home and will continue to protect you in future seasons!

Lasting basement waterproofing system in Kansas City

With Kansas City’s extreme weather fluctuations, there is plenty to worry about when keeping your basement dry and secure. Not only can expansive soils, foundation heave, and dry air cause leaky cracks in the below-grade space, but Kansas City is also a part of the humid subtropical zone, meaning the summers are long, hot, and humid. This is bad news for basements, as once outside air touches cold appliances, condensation forms, creating the perfect breeding ground for mold. Plus, outlying areas in Kansas City are subject to flooding, putting those homes even more at risk.

Being proactive is the best way to keep your basement dry and safe in the ever-changing Kansas City climate – and Thrasher Foundation Repair knows just what to do to help. We have provided reliable basement waterproofing solutions for homeowners since 1975, eliminating basement flooding and moisture intrusion problems and keeping their below-grade spaces dry for years.

Schedule a free basement waterproofing inspection and service estimate to learn more. We proudly serve Kansas City and nearby areas in Missouri.

Our basement waterproofing system includes:

  • Interior drainage systems
  • Sump pumps
  • Window wells
  • Mold treatment
  • Dehumidifiers
  • And more!

Crawl space repair & encapsulation services in Kansas City

The crawl space can already be a nasty, humid place, creating the perfect breeding ground for mold and pests. But since Kansas City is known for its long, hot, and humid summers, this can be very detrimental to the crawl space. Plus, some areas of the city are prone to flooding – and if your crawl space isn’t secure, this could cause serious problems for your home. Once you factor in the extreme temperature fluctuations common in Kansas City, you could have quite the problem on your hands. The humid, hot summers and icy, cold winters can cause foundation heave and expansive soils, creating a weaker structure overall and causing leaky cracks in the below-grade space.

So when it comes to creating a dry and secure crawl space, trust the experts who have been providing these services since 1975. Our crawl space encapsulation and repair solutions seal off your space the elements and even stabilizes it, assuring a moisture-proof area that is protected for years to come.

Our crawl space repair system includes:

  • Crawl space vapor barrier
  • Crawl space insulation
  • Crawl space support posts
  • Crawl space dehumidifiers
  • Crawl space sump pumps
  • And more!

Owners of public buildings must be very cautious about having tripping hazards on sidewalks.

All concrete slabs settle – it’s a matter of when, not if, it will happen.

The Raytown School District has used Thrasher Foundation Repair on many occasions to maintain the safety of the sidewalks and flatwork around their schools and office buildings.

Owners of most public buildings are required to repair any public sidewalk or entryway that has more than 3/4″ differential movement from one piece of flatwork to another.

Thrasher was hired to eliminate any potential tripping hazards along the sidewalks and entryways at one of the district's office buildings. We were able to return all the concrete flatwork to the original condition without interrupting their working schedule or the facility's function.

Although we do not use or provide mudjacking services today, we provide a polyurethane injection system, PolyLevel, to offer an economical, quick and effective solution for lifting situations like these and residential sidewalks, patios and driveways.  

Sunken or heaved concrete slabs can present tripping hazards that you may be liable for as a homeowner. Concrete repair is essential to protect your driveway, sidewalk or patio for the future. 

At Thrasher Foundation Repair, we use PolyLevel® for concrete leveling because it's a fast and effective way to lift and stabilize sinking concrete. 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 slabs without adding weight to the soil beneath, and it's waterproof so that 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 them, creating a stable environment that will ensure that your driveway, patio or pool deck remains level into the foreseeable future.

Our comprehensive concrete protection system provides additional durability:

  1. Your concrete is lifted and leveled using PolyLevel® foam.
  2. Your cracked concrete and control joints are filled and sealed using NexusPro joint sealant.
  3. The whole surface is protected from the elements with a coat of SealantPro™, which permanently bonds to your concrete.

When you lift, level and protect your home's concrete, you can rest assured it will keep looking and working great well into the future — plus, you'll sleep better knowing you've got a five-year warranty.

When we visit your home for the first time, you can expect a thorough inspection and a detailed explanation of the concrete leveling solution we propose and why. We offer several levels of protection and transparent pricing to meet your specific needs. 

We use PolyLevel to lift and level concrete. PolyLevel polyurethane foam is pumped beneath cement 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 ground 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 ecologically harmful chemical leaching. Best of all, PolyLevel cures quickly, allowing your concrete to be used usually the same day.

Eric is a proud retired homeowner in Raytown, MO and plans to keep the estate as his forever home. However, Eric loves to travel and knows that if he ever wanted to sell the property a few issues would need to be taken care of first. Specifically, his driveway and surrounding concrete needed to be leveled and repaired to restore the property’s value. Eric was familiar with Thrasher and our dedication to providing the best solution. Looking for a company that does it right the first time, he gave Thrasher a call.

To begin the project, our System Design Specialist Tom Studer arrived in Raytown to perform a thorough inspection of the home. The driveway and sidewalks had multiple areas of settlement that had caused cracks and an uneven surface. The back patio had sunken areas that created a tripping hazard when entering the home. Both issues were caused by the soil underneath being washed out and not being able to support the weight of the concrete. This was solved using our PolyLevel foam to permanently lift and level the concrete. It’s a lightweight and waterproof solution that guarantees no soil washout in the future without adding any extra weight. This was then paired with our NexusPro sealer to fill all cracks and control joints to prevent any water from seeping through. These two products combined not only increase the lifespan of the concrete but enhance the appearance in order to increase the property’s value.

Eric was pleased with the outcome of the solutions Thrasher was able to provide. He was impressed with our ability to provide a quality customer experience, and with his concrete repaired Eric now has the confidence to live on in his forever home.

Erica B. is a homeowner in Kansas City, MO that had major concerns with her front concrete walkway leading to her house. It had settled over the years causing it to slant downhill and crack in multiple areas. The walkway had gotten so severe that Erica avoided using the walkway in the winter out of caution of her own safety. She knew the walkway was only going to get worse, so she decided to have it repaired. She chose Thrasher because of our dedication to providing a permanent and effective solution.

To begin the concrete repair, System Design Specialist Tyler Lothrop arrived at the home in Kansas City to perform a full inspection on the walkway. It was determined that the settling of the concrete occurred because of poor soil conditions and drainage that washed the soil out. Erica opted to have the team install our 2-Part Concrete Protection System to level and seal the concrete. Our PolyLevel foam was installed first by injecting it underneath the sunken concrete to permanently lift and level it. NexusPro sealer was then applied to all cracks and control joints to prevent any water intrusion and problems from occurring in the future.

Erica was excited and relieved to have her walkway functional once again. We take pride in being able to restore a homeowner’s peace of mind and increasing the value of their home.
