Concrete Leveling in Charleston, SC

Concrete Leveling in Charleston: local conditions

Charleston, SC sits on clay piedmont soils, sandy toward the coast and has a humid subtropical climate with about 48" of rain a year. The local water table is high near the coast and lowcountry, with mild winter freeze–thaw cycling, and crawl spaces and slabs dominate and basements are rare. In practical terms, high rainfall, hurricanes and humid crawl spaces make moisture control central — which is exactly why concrete leveling is a common need here.
