Shanghai Yingfan “Yingfan” brand bentonite waterproof blanket (English name: GCL) consists of three layers, the upper and lower layers are respectively geotextiles, mainly for protection and reinforcement, so that it has a certain overall puncture strength and tensile strength. The middle is a sodium-based bentonite grain layer, which is processed from natural clay mineral machine material, has high expansion and high water absorption capacity, and has low water permeability when wet, and mainly serves as an anti-seepage effect. The bentonite waterproof blanket adopts the special acupuncture method. The special acupuncture process is to make the coarse fiber from the upper layer geotextile through the bentonite layer, fix it on the lower layer geotextile, and combine the three parts into one, effectively enhancing the bentonite waterproof blanket. The integrity of the bentonite waterproof blanket greatly enhances the shear strength and tensile strength, which allows the swellable waterproof blanket to be used alone or in combination with a compacted clay barrier or geomembrane.
