Several municipalities have made full-height basement insulation mandatory. Under these standards, basement walls are sandwiched between vapor barriers on the interior and waterproofing on the exterior, allowing moisture to build up. Delta-Footing Barrier from Cosella-Dörken Products creates a capillary break between footer and foundation that keeps groundwater from entering and accumulating in basement walls. Able to accommodate the forming of keyways in the footer, the three-ply membrane consists of an antislip surface, an impermeable polyethylene barrier, and a polyester needle-punched fabric for maximum adhesion. cosella-dorken.com
