Dimple Drainage Mat Crawl Space Vapor Barrier, 3.28 x 32.8 ft

Key features

• Ideal for Crawl Space Encapsulation & Basement Waterproofing: this dimple drainage mat creates a continuous air gap that channels water toward sump pumps or French drains, effectively preventing ground moisture, vapor intrusion, and humidity from entering crawl spaces and basements
• Superior HDPE Construction with 10mm Dimple Height: crafted from heavy-duty High-Density Polyethylene (HDPE) with compressive strength over 200 kPa and 10mm raised dimples — engineered to withstand hydrostatic pressure while maintaining structural integrity in permanently wet environments
• Versatile Foundation Underlayment: designed for crawl space liners, basement floor underlayment, foundation wall drainage, below-slab applications, and exterior wall waterproofing
• Easy DIY Installation: the lightweight white design (highly visible in dark spaces) unrolls smoothly and cuts with standard utility knife or shears; seal seams with tape for a seamless waterproofing system — no special tools required
• 108 Sqft Complete Coverage Roll: one roll covers 108 sq ft (3.28 ft × 32.8 ft), ideal for targeted basement sections, crawl space perimeters, or specific problem areas; minimize seams for comprehensive protection
