Three Dimensional Composite Drainage Net

Product Overview: Three Dimensional Composite Drainage Net The Three Dimensional Composite Drainage Net is the core mesh component of standard Drainage Board, made of high-density polyethylene with interwoven triple-layer rib structure. It can be matched with Bentonite GCL and Erosion Control Mat to form multi-layer geotechnical systems for drainage, anti-seepage and slope protection. Core Advantages The crisscross three-dimensional ribs form continuous hollow drainage channels to quickly discharge underground water and reduce hydrostatic pressure on base layers. As the core part of Drainage Board, it maintains stable void space under heavy soil compression without collapse. When assembled under Bentonite GCL, it timely diverts seepage water to prevent liner swelling and leakage damage. Paired with Erosion Control Mat on slopes, it achieves underground drainage and surface soil retention simultaneously to avoid slope sliding. The HDPE material provides strong anti-aging and acid-a…
