4m~6m Width Customizable Bentonite Geosynthetic Clay Liner For Seepage Control And Isolation
Product Introduction
The bentonite waterproof blanket is filled between a specially made composite geotextile and a non-woven fabric with highly expansive sodium bentonite. The bentonite impermeable mat made by needling method can form many small fibered manifold, is the bentonite particles can not flow like a direction, in case of water in the cushion to form a uniform high-density gel waterproof layer, effectively prevent water leakage.
Product Properties
Compared with the compacted clay liner, it has small volume, light weight, flexibility, good sealing performance, high shear strength, simple construction and adapt to uneven settlement, etc.
Product Application
Mainly used in environmental engineering constructions, such as waste landfill, underground reservoir, underground infrastructure construction projects, to solve the seal, isolation, seepage control and related problems, good effects and strong destruction resistance.
