Crawl Space Encapsulation in Raleigh, NC

Crawl Space Encapsulation in Raleigh: local conditions

Raleigh, NC sits on clay piedmont soils, sandy toward the coast and has a humid subtropical climate with about 44–48" of rain a year. The local water table is higher near the coast and river basins, with mild winter freeze–thaw cycling, and crawl spaces are very common; basements mostly in the mountains. In practical terms, high rainfall, hurricanes and humid crawl spaces make moisture control and encapsulation central — which is exactly why crawl space encapsulation is a common need here.
