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 house 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 foundation problems may need a more personal touch. In fact, we have been providing customizable and permanent house foundation repair solutions to homeowners since 1975.

Waterproofing contractor in Kansas City providing lasting solutions

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. As experienced waterproofing contractors, 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.

Our basement waterproofing system includes:

  • Interior drainage systems
  • Sump pumps
  • 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. We proudly serve Kansas City and the surrounding areas.

Our crawl space repair system includes:

  • Crawl space vapor barrier
  • Crawl space insulation
  • Crawl space support posts
