Cuspated Sheet Drainage - 1.5 x 20m

Our Cuspated Sheet Drainage Rolls (1.5m x 20m) provide an efficient and durable solution for subsoil and wall drainage applications. Designed for civil, landscaping, and construction projects, these high-strength drainage sheets help manage groundwater, prevent hydrostatic pressure, and protect waterproofing membranes.

• 10mm Thickness: Ideal for light to medium drainage applications such as retaining walls, planter boxes, and foundation protection.

• 20mm Thickness: Best suited for heavy-duty drainage where higher flow capacity and load-bearing strength are required, including civil infrastructure, basement walls, and podium decks.

Manufactured from high-density polyethylene (HDPE), the cuspated core offers exceptional compressive strength and long-term flow performance. The sheets are lightweight, easy to install, and suitable for use both vertically and horizontally behind retaining walls, basements, tunnels, and green roofs.
