High-Density Polyethylene (HDPE) Dimpled Drainage Board for Waterproofing and Foundation Protection

This professional HDPE Dimpled Drainage Board is engineered to provide a robust dual-layer solution for waterproofing and subsurface water management. Its specialized dimpled structure creates a permanent air gap between the structure and the soil, allowing for rapid water diversion while protecting the primary waterproof membrane from mechanical damage. It is an essential component for basement walls, underground garages, tunnel linings, and roof gardens.
