Short filament composite geomembrane

Product introduction

Short Filament Composite Geomembrane is a new type of composite geotechnical material made of short fiber needle-punched geotextile and anti-seepage membrane through a thermal composite process. It has excellent anti-seepage, high strength, aging resistance, puncture resistance, and other properties. It is widely used in anti-seepage, protection, and reinforcement systems in water conservancy projects, environmental protection projects, municipal projects, transportation projects, and mining.

Convenient construction is a major advantage of this material. It can be spliced ​​in a variety of ways, such as hot air welding, gluing, or mechanical connection. It has high construction efficiency and good connection strength, which effectively improves the convenience and reliability of on-site operations. According to different project requirements, a variety of structural forms, such as single membrane, double cloth, and double membrane single cloth, can be selected to meet differentiated protection functions.

As a composite geotechnical material with excellent performance and a wide range of applications, Short Filament Composite Geomembrane is an important choice for achieving safe anti-seepage, long-term stability, and efficient construction.

Material technology

This material combines the good mechanical properties of geotextile and the excellent anti-seepage properties of geomembrane to form a protective layer with stable structure and strong integrity, which can effectively resist various engineering risks such as water flow, leakage, and soil particle migration. Short fiber geotextile provides good drainage, anti-filtration and reinforcement functions, while the anti-seepage membrane effectively blocks liquid penetration. The composite of the two significantly improves the comprehensive performance of the material.

Short Filament Composite Geomembrane has good flexibility and deformation adaptability. It can still maintain a complete structure when the foundation settles or the slope deforms. It is suitable for irregular terrain or complex environment. Its acid and alkali resistance, UV resistance, and corrosion resistance enable it to operate stably for a long time in harsh environments, extending the service life of the project.
