Hillside basement seepage

Karst settlement

Limestone under parts of East Tennessee can form voids and sinkholes, causing localized settlement.

Historic brick foundations

Older brick foundations need compatible mortar and interior drainage.

Mid-century homes in Fountain City and Bearden often have crawl spaces with dirt floors and failing vapor barriers. A new heavy barrier, drainage and dehumidification reduce moisture and musty odors.
