HDPE dimpled drainage board
HDPE dimpled drainage board (concave‑convex drainage sheet), manufactured in Shandong, China. Made of high‑density polyethylene, high compressive strength, anti‑aging, chemical‑resistant, root‑resistant.Dimple height optional:8‑50 mm; roll width 1m /2m, roll length 10‑20 m. Weight range:650‑1800 g/m². Can be compounded with non‑woven geotextile as filter layer.Mainly used for green roof, garage top drainage, basement wall protection, tunnel, landfill, slope and transportation construction projects.3‑year warranty, online technical support. We provide drawing design, 3D‑model, full‑project solution and cross‑category material matching service.

- Underground garage & basement: Relieve water pressure, protect waterproof layer, avoid leakage and dampness.
- Green roof & landscape projects: Fast drainage, root resistance, improve plant survival rate.
- Tunnel engineering: Side wall & vault drainage, reduce hydrostatic pressure, protect tunnel structure.
- Highway & railway subgrade: Drain retained water, stabilize roadbed, prevent settlement and deformation.
- River, lake & slope projects: Balance backwater pressure, prevent geomembrane bulging and slipping.
- Our HDPE dimpled drainage board adopts 3D hollow structure for efficient & stable drainage. Widely used in tunnel, road subgrade, underground garage, green roof and water conservancy projects. Made of virgin HDPE, it features high compression resistance, anti-clogging, anti-aging and easy installation. We provide one-stop customized drainage system solutions for global infrastructure projects.
