Before and After Pictures from Leawood
Retaining Wall Replacement

Retaining Wall Replacement

Before After
Retaining Wall Replacement Retaining Wall Replacement

A local homeowners’ association was experiencing deteriorating timber retaining walls that required complete replacement.

Thrasher Foundation Repair replaced the retaining wall and addressed drainage issues.

Thrasher engineered a more structurally sound foundation repair solution by constructing modular block walls. The new block walls offer a more pleasing curb appeal and design, while still providing a structural and permanent foundation.

Thrasher successfully gave this property an effective and beautiful makeover.

A drainage issue that was affecting the growth of some of the association’s decorative trees was also addressed. The trees were saved by integrating a drainage system behind the new block retaining walls and managing the runoff water.

This customer has a pool in their backyard and discovered that the concrete around it was sunken. She wanted to get it fixed so that it couldn't get any worse. Our team was able to lift the sinking concrete back to its original position using PolyLevel, a polyurethane foam that is injected beneath the slab to stabilize it. To finish off the project, we sealed all the cracks and joints for long-term protection. Now this homeowner can enjoy their pool without having to worry about their concrete!

Lifted and leveled, check! We lifted this sinking concrete back to its original position with our product called PolyLevel. Using a Poly gun, we inject the hardening foam into the voids beneath the concrete. Once the foam hardens, it stabilizes and supports the concrete slab above it.
