Details Description

Geomembranes are essential synthetic materials in modern construction and environmental protection. Composed of polymers like HDPE, LDPE, PVC, or EPDM, these continuous, flexible membranes serve as highly effective low - permeability barriers. Their core function is to prevent the seepage of liquids and gases, making them crucial for applications such as landfill liners to contain waste, reservoir and canal liners to conserve water, and mining tailings dams to manage hazardous materials.

Geomembranes stand out for their durability, chemical resistance, and ability to adapt to irregular terrains. With customizable thickness, width, and material properties, they offer versatile solutions across various industries, from agriculture to energy. By providing reliable containment and protection, geomembranes play a vital role in safeguarding the environment and ensuring the long - term integrity of civil engineering projects.
