Product Overview: Shandong Tianhai Composite Geomembrane is a geosynthetic material made by laminating and thermally bonding more than two materials, including geotextiles (non-woven geotextiles, woven geotextiles, plastic woven fabrics, etc.) and polymer materials (HDPE film, LDPE film, EVA film, etc.). Performance Characteristics: ◎ Our company has over ten years of production experience in composite geomembranes, effectively addressing defects such as uneven width and length, non-uniform film thickness, and numerous holes produced during lamination. Every product that leaves our factory undergoes strict inspection, maximizing its performance in engineering applications. ◎ Our company has developed into a production enterprise that incorporates both calendering and thermal lamination processes. The product width reaches 7 meters, reducing seams compared to narrower similar products, lowering project costs, shortening construction periods, and minimizing risks caused by improper seam treatment. ◎ The composite geomembrane uses geotextiles instead of granular materials as a protective layer for the geomembrane's impermeable layer, protecting it from damage, lowering the requirements for the gradation of the cushion layer, and providing drainage capabilities. ◎ The composite geomembrane has a high friction coefficient, preventing the sliding of the covering layer. Compared to pure HDPE films, the non-woven fabric in the composite geomembrane has a greater friction coefficient, allowing for a steeper slope and reduced land occupation. ◎ The composite geomembrane has high mechanical strengths, including tensile, tear, puncture, and burst resistance. ◎ The composite geomembrane can deform to a certain extent, quickly dissipating stress caused by the unevenness of the cushion layer, and has strong strain capacity. ◎ The pore water pressure and buoyancy force at the contact surface between the composite geomembrane and the soil are easily dissipated. ◎ The composite geomembrane has a certain amount of thermal insulation, reducing damage from soil frost heave to the geomembrane and consequently minimizing soil deformation. ◎ The composite geomembrane is installed in a buried manner, exhibiting excellent anti-aging performance, which reduces maintenance and upkeep of the project. ◎ The installation of the composite geomembrane is simple, reducing transportation volume, lowering project costs, and shortening construction periods.
