Job Stories From Ottawa, KS
Foundation Repair in Ottawa, KS

This homeowner in Ottawa, KS inherited the home but was concerned with the integrity of the foundation. The customer knew there was an issue because sunlight was breaching through a gap in the floor joists above the wall. In order to sell the home soon, they wanted to have the foundation repaired and maximize its value. After meeting with a Thrasher System Design Specialist, they knew they could trust our reputation of providing the best quality solutions.

It was determined that there was an existing wall support system that wasn’t maintained and failed as a result. To fix the problem, Thrasher excavated and straightened the wall with our PowerBrace wall support system and GeoLock wall anchors. The PowerBrace stabilizes the wall in its current position, and then the GeoLock anchors straighten them over time. The customer was relieved to have their foundation issues repaired knowing they can move forward in the selling process.
