High Flow Plastic Dimple Drainage Membrane

Product Overview: High Flow Plastic Dimple Drainage Membrane The High Flow Plastic Dimple Drainage Membrane is a lightweight HDPE Drainage Board designed for efficient underground water diversion. It can be deployed together with Bentonite GCL and Erosion Control Mat to build complete geotechnical systems with drainage, anti-seepage and slope protection functions. Core Advantages Uniform raised dimples create large unobstructed flow channels to deliver superior high-flow drainage capacity, rapidly releasing hydrostatic pressure from foundations. As a durable Drainage Board, the rigid dimple structure resists heavy soil compression and keeps drainage cavities intact for long-term use. When laid underneath Bentonite GCL, it drains trapped seepage water to avoid liner deformation and leakage risks. Paired with Erosion Control Mat on exposed slopes, it separates surface soil and underground water, reducing runoff erosion and preventing slope sliding. The HDPE material features excelle…
