Release time:
2026-01-12
In the field of geotechnical engineering, the two-layer geotextile-one-layer membrane composite membrane, with its innovative "fabric-membrane-fabric" structure, has become a core material for seepage control and reinforcement, widely adaptable to various engineering needs. This composite geomaterial is made by heat-sealing two layers of needle-punched nonwoven geotextile sandwiching a layer of high-density polyethylene (HDPE) membrane. Typical specifications include 200g/0.5mm/200g, balancing both strength and seepage control advantages.

The two layers of geotextile act like "protective armor," not only improving the material's tensile strength and puncture resistance but also enhancing friction with the soil, preventing damage to the membrane during construction and use. The middle PE membrane serves as the core seepage control layer, with a permeability coefficient as low as 1.0×10⁻¹²cm/s, effectively blocking water and chemical leakage, meeting the national standard GB/T 17642-2008. The product also possesses properties such as UV resistance, corrosion resistance, and aging resistance, with an outdoor service life of over 50 years. It is lightweight, easy to install, and significantly reduces construction costs.
From seepage prevention in reservoirs and channels of water conservancy projects, to landfill pollution prevention in the environmental field, to roadbed reinforcement in transportation engineering, basement waterproofing in municipal engineering, and even seepage prevention in artificial lakes in landscaping and water-saving renovations in agricultural irrigation, the two-layer fabric-one-layer membrane composite membrane plays a crucial role. Its characteristics of "stable structure, balanced performance, and wide applicability" make it a preferred green and efficient material in modern engineering construction, building a solid seepage prevention line for project quality.
