HDPE Composite Bentonite Waterproof Liner

Product Overview: HDPE Composite Bentonite Waterproof Liner The HDPE Composite Bentonite Waterproof Liner is an integrated composite anti-seepage material, a reinforced upgraded type of Bentonite GCL. It can be matched with Drainage Board and Erosion Control Mat to build multi-layer anti-leakage and slope protection systems for environmental and hydraulic engineering. Core Advantages This composite liner combines HDPE film and bentonite clay core, merging the high impermeability of HDPE membrane and the self-repair feature of standard Bentonite GCL. When minor scratches appear, hydrated bentonite swells to seal gaps automatically, effectively preventing liquid leakage. Laid with Drainage Board, it quickly guides accumulated underground water away to avoid liner bulging and damage. Covered by Erosion Control Mat on the surface, it gets full protection against direct sunlight, rain wash and sharp soil fragments, extending its underground service life significantly.
