Crawlspace Waterproofing

The debate in the building science engineering community over vented or closed crawl spaces has gone on for more than twenty years. A widely accepted, definitive study by Bruce Davis with Advanced Energy ( about crawl spaces, began in early 2001, with the final report published on June 22, 2005, to determine the best solution to often dangerously damp and energy-wasting crawlspaces. This field study, financed by the U.S. Department of Energy, clearly shows that homes in the southeastern United States will benefit in several important areas by controlling rain water intrusion, closing foundation vents, sealing the earth (or concrete) crawlspace floors, insulating exterior foundation walls, dehumidifying the closed crawlspace area and providing make-up air, if needed.
