Product Description

Introduction

Composite geomembranes are widely used in canal anti-seepage engineering. The extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and emergency engineering, have attracted high attention from engineering and technical personnel. From the aspects of anti-seepage, filtration, drainage, reinforcement, protection, etc.

1. One cloth, one film (cloth: 100-1000g/m2, film thickness: 0.1-1.5mm)
2. Two cloths and one film (cloth: 80-600g/m2, film thickness: 0.2-1.5mm)
3. One cloth and two films (cloth: 100-1000g/m2, film thickness: 0.1-0.8mm)
4. Multi cloth and multi film (cloth: 100-1000g/m2, film thickness: 0.1-0.8mm)

Composite geosynthetic membrane is a geosynthetic anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (HDPE, LDPE, LLDPE), and ethylene/vinyl acetate copolymer (EVA)，Civil engineering needs such as anti-seepage, isolation, reinforcement, and crack prevention reinforcement in water conservancy, municipal engineering, construction, transportation, subway, tunnel, and engineering construction. Commonly used for anti-seepage treatment of embankments, drainage ditches, and waste disposal sites.
