Job Stories From Excelsior Springs, MO
Foundation Repair in Excelsior Springs, MO

Chuck's home was built in 2000. A few years ago, he started seeing those very common stair-stepping cracks on the brick of his home. Once he realized his kitchen backsplash was beginning to pull away, he realized he had a bigger problem. To maintain his home and prevent further damage, he called Thrasher. 

We sent out Tom Studer to look at Chuck's foundation and develop a plan to fix the issues. Tom found that the extreme weight of the home was causing the soil particles to consolidate tighter, which then caused the home's footing to drop. To fix this, our team installed our push pier system to stabilize and lift a portion of his house. This helped push the cracks on the brick closer together. Our Push Pier system is highly effective; the piers are made of galvanized steel that fit together to reach depths where they can find firm footing in load-bearing soil. They are anchored with pier brackets that extend under the entire foundation wall, shifting the weight onto the push pier and leveraging its push into the ground.

Chuck was pleased with the results and is now less stressed about his home's foundation!

Removed Drywall Revealed Structural Foundation Damage in this Kansas City Fixer Upper

Terry M. bought this home with hopes to fix it up and use as a rental property. Once water started coming in through the basement, Terry wanted to get to the bottom of it. After removing drywall in the basement, it was revealed this house had more than just surface level issues. They found extreme bowing of the wall and structural damage to the foundation. 

After finding these structural issues, Terry was at a crossroads: cut their losses and sell to a fixer-upper company or invest in their property and fix the foundation. Terry started reaching out to a few foundation repair companies and the only one that would help them with repairing both the foundation wall and water damage was Thrasher Foundation Repair.

When we came out on site to inspect the home, we advised that in order to keep the foundation wall from caving in, we needed to rebuild it completely. We suggested our Everbrace System to stabilize the house from the foundation wall collapsing inward because of the extreme hydrostatic pressure that was built around the foundation. On top of that, we also recommended our WaterGuard system for the foundation wall because we noticed water was leaking in through the cracks on the walls and flooding the basement during heavy rainfall.

Now Terry can get back to work, fix up this home, and start using it as a rental property, knowing that his future renters would not have to live in a home with a wet basement and foundation problems.
