Crawlspace Depot has a wide selection of high quality wall and floor liners to meet your closed crawlspace needs.
A translucent poly wall liner is generally run along the length of the interior crawlspace foundation walls. It is then sealed at the top with an adhesive compound and sealed to the floor liner with sealing tape. Wall liner is also used to wrap piers.
Floor liner is generally used to cover 100% of the ground. All edges are sealed to the wall liner with tape and also sealed to the wall liner at all piers or directly to Bora-Foam (if applicable). Available in 6 mil, 8 mil and 12 mil thicknesses.
