Proven Concrete Solutions in Kansas City

Your concrete is affected by the unpredictable weather patterns of Kansas City. At Thrasher Foundation Repair, we offer three main concrete repair solutions, all fully equipped with a 5-year warranty.

Concrete leveling

Sinking concrete is no match for our patented concrete leveling system at Thrasher Foundation Repair. PolyLevel is a lightweight, polyurethane foam that is exclusive to specific concrete repair contractors. It expands upon application to lift and support your concrete without placing anymore weight on the soil below. PolyLevel is quick to cure, which means you will usually be able to use your concrete that day.

Concrete caulking

NexusPro is our main concrete caulking solution at Thrasher Foundation Repair. It is a silicone-based crack and joint sealant that is durable enough to prevent moisture from seeping beneath your concrete. NexusPro is resistant to UV rays, which means it will not crack, bubble or dry.

Concrete sealing

Permanently sealing your concrete is simple with our SealantPro solution. SealantPro extends your concrete’s life by 3-5 times with just one application. The value and curb appeal of your Kansas City home instantly increase with the sleek look of this product. It even reduces ice bonding, which makes ice removal easier.
