3D Dimpled Plastic Drainage Board

Product Overview: 3D Dimpled Plastic Drainage Board The 3D Dimpled Plastic Drainage Board is a classic single-layer HDPE Drainage Board with concave-convex protrusion structure. It can be matched with Bentonite GCL and Erosion Control Mat to build integrated drainage, anti-seepage and slope protection systems for water conservancy, environmental and civil engineering. Core Advantages Uniform raised dimples form stable vertical and horizontal drainage channels, rapidly draining accumulated underground water to reduce hydrostatic pressure on base layers. As standard Drainage Board, it bears heavy soil compression without collapsing the drainage gaps, maintaining long-term unobstructed water flow. When laid beneath Bentonite GCL, it timely diverts seepage water to avoid bulging and damage to the anti-seepage liner. Combined with Erosion Control Mat on slope surfaces, it achieves surface soil retention and underground water discharge simultaneously to prevent slope collapse. The HDPE…
