Before & After Photos

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.

Did you know that the road in front of your house can hurt your foundation? Concrete grows when it's hot and shrinks when it's cold. To reduce the issues caused by temperature changes, Thrasher installs expansion joints in exterior concrete slabs such as sidewalks and driveways. These joints absorb and spread out the stress, allowing the concrete slabs to expand and contract without touching, which lessens the risk of cracking.

However, over time, standard expansion joints may deteriorate, crack, or become filled with debris. When this occurs, the concrete expands altogether, resulting in street creep and a lot of pressure where the driveway meets a garage slab or foundation wall.

To Prevent this, we used Compression Guard on this driveway, which fills the joint in a way that reduces the problems we see with standard expansion joints. 

Make your home healthier and safer with crawl space encapsulation – a smart investment that brings many benefits. Encapsulating your crawl space keeps your space dry and the air inside clean. Keeping you and your family safe from mold, bugs, and potential damage. Plus it'll keep your energy bills down! Check it out in this before and after. 

This homeowner wanted to repair the downstairs bedroom so she could host her grandkids. In this bedroom, the concrete floor was sinking about 3" in the center of the room. We were able to lift and level the floor using PolyLevel, a polyurethane foam, so now it no longer feels like the room is sinking.

This Overland Park foundation repair job included the installation of foundation piers, as well as epoxy crack repair.

A qualified foundation repair contractor or structural engineer should be consulted to determine if a crack in your foundation is merely cosmetic or of a more serious nature.

The goals for this residence were to achieve a minimal lift, to stabilize the structure on the east and south foundation walls, and to close the large crack on a corner. Thrasher and the consulting geotechnical engineer determined that resistance piers would be ideal to provide supplemental support in this situation.

The photos below show the large diagonal crack that had appeared on the corner of the foundation wall. The crack gaped open a half-inch or more.

Thirteen resistance piers were installed along the interior of the east and south foundation walls. Twelve linear feet of urethane injection was used to fill and seal the large crack after the piers were installed. The piers were hydraulically pushed into the soil beneath the home until a predetermined load-bearing stratus was reached.
