Foundation Repair Case Studies: Sinkhole in Madisonville

Friday, December 1st, 2017 by Brittney Gebers


This Madisonville, Kentucky home was having a long list of foundation problems because of a sinkhole. The homeowners had made an insurance claim and wanted to save their home by stabilizing the foundation. The evidence was obvious inside the home but as the crews dug, the findings were scary.

An insurance representative for the home owner said that the house was built on top of where mine activity occurred and has caused issues with the structure and foundation of the home. He sent me an email with the engineer report, insurance will cover the work. Our office called the home owner to schedule the inspection.
