A SuperSump drainage system was installed in this crawl space at construction to help distribute groundwater from the crawl space away from the home. While this addressed the bulk water issues from the ground and heavy rains, it did not prevent condensation and moisture from damaging the fiberglass insulation or floor joists or prevent mold from growing. Once we added the Foamax and CleanSpace, and sealed the crawl space vents, rim band, and sill plate, and installed a dehumidifier not only was the home protected from bulk water, but it is protected from future moisture damage.
