Impermeable Bentonite Clay Waterproof Blanket

Product Overview: Impermeable Bentonite Clay Waterproof Blanket The Impermeable Bentonite Clay Waterproof Blanket, also named Bentonite GCL, is a high-performance composite anti-seepage geosynthetic material. It can be matched with Drainage Board and Erosion Control Mat to form complete multi-layer engineering systems integrating anti-seepage, drainage and slope protection. Core Advantages Natural sodium bentonite inside swells quickly after contacting water to form a dense waterproof barrier with self-repair ability for tiny scratches and gaps. When laid above Drainage Board, it guides seepage water away efficiently and reduces hydrostatic pressure that may damage the blanket. Covered by Erosion Control Mat on exposed slopes, it is protected against water scouring, sharp stones and UV aging to extend service life. The dual geotextile clamping structure offers strong tensile and anti-puncture performance to adapt to foundation deformation. Detail Features This Bentonite GCL ad…
