Two Fabrics and One Film The Strongest Composite Geomembrane for High-Intensity Projects

Introduction

Geosynthetic composite membranes are impermeable materials that combine plastic films and non-woven fabrics. They are widely used in civil engineering to enhance the impermeability of projects.

Application Scenarios

Channel Seepage Prevention Project: Due to its excellent seepage prevention performance, composite geomembrane is widely used in channel seepage prevention projects.
Landfill: In landfills, composite geomembranes can effectively prevent the leakage of leachate, protecting the environment.
Artificial Lakes and Underground Projects: Due to its weather resistance and durability, composite geomembranes are also commonly used for waterproofing in artificial lakes and underground projects.

Structure and Classification

The composite geomembrane is mainly divided into two types:

Geotechnical fabric and film: Consists of a layer of geotechnical fabric and a layer of plastic film.
Two fabrics and one film: consists of two layers of geotechnical fabric and one layer of plastic film, offering higher strength and durability.

Construction Method

The construction methods of composite geomembrane include:

Burial Method: Bury the composite geomembrane in the soil, cover it with fine sand, and compact it.
Welding Method: Connect the various parts of the composite geomembrane through thermal fusion welding or extrusion welding.

Advantages and Application Advantages

High Intensity: Exhibits good tensile strength and tear resistance.
Durability: Under normal conditions of use, the service life can reach 50-70 years.
Environmentally Friendly: Suitable for environmental protection projects such as landfills and artificial lakes, reducing the impact on the environment.

To sum up, the composite geomembrane, with its excellent impermeability and wide range of applications, has become one of the indispensable materials in modern civil engineering construction.
