I saw sinkhole property repaired where they went down to bedrock and pumped in grout to form firm foundation from 90 ft deep to the surface around the whole house. Cost was about $90,000. That property seems better protected from sinkholes than any of the neighbors or most other properties in the villages. Seems strange that insurance company won't go near well engineered foundation and will insure untested properties.
Is there a way to assess sinkhole risk?
