Apex & Wake County Geology: Triassic Basin Red Clay & Drainage
Apex is situated in western Wake County within the Piedmont region. The defining geological feature of Apex is dense Piedmont red clay soil with low hydraulic permeability. During heavy rainstorms, water can pool against foundation walls.
Clay soils hold water against foundation walls. As ambient temperature rises in summer, ground moisture inside unsealed crawl spaces evaporates into trapped foundation spaces, raising humidity above 75%.
Wake County homeowners sometimes notice subfloor moisture when hardwood floors begin to cup. Rising humidity causes subfloor timber absorption, which contractors address by installing sealed vapor retarders.
