Composite geomembrane with Filament geotextile for Dam
Composite geomembrane is divided into a cloth a film and two cloth a film, a wide width of 4-6m, according to different specifications of different weights, generally 200-1500g/square meter, tensile, tear resistance, top break and other physical and mechanical performance indicators are high, the product has high strength, good extension performance, deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, good impermeability and other characteristics.It can meet the needs of civil engineering such as water conservancy, municipal, construction, transportation, subway, tunnel, engineering construction, seepage prevention, isolation, reinforcement, crack prevention and reinforcement.It is often used for anti-seepage treatment of DAMS, drainage ditches, and anti-pollution treatment of waste yards.
Specification：
One cloth with one membrane/Two cloth with one membrane/One cloth with two membranes
Width: Generally 4M-8M, commonly used 4m, 5.8m, 6m, 7m, 8m and so on.
Length: Flexibly customized according to different requirements and application scenarios.
Engineering Applications：
Hydraulic Engineering
In reservoir cutoff walls, using sandwich structure (1.0mm HDPE + 600g/m² PET geotextile) achieves seepage control <5L/(m²·d).Waste Containment
Hazardous landfill systems employing 2mm HDPE composite with GCL clay liner achieve dual containment (k≤1×10⁻¹² cm/s).Transportation Infrastructure
Needle-punched composites in high-speed rail subgrades effectively control capillary rise, showing 40% CBR improvement in freeze-thaw cycling tests.

Key Advantages：
Composite Functional Design
Multilayer structure formed by thermal bonding of geomembrane and nonwoven geotextile (typical configuration: 0.3-2.0mm HDPE + 200-600g/m² fabric), achieving synergistic waterproofing and drainage. Lab tests show permeability coefficients as low as 1×10⁻¹³ cm/s.Enhanced Mechanical Properties
Demonstrates tensile strength of 20-40kN/m (ASTM D4595) with elongation exceeding 400%, capable of accommodating 3-5% subgrade differential settlement.Environmental Resistance
Certified per GB/T17643-2011, maintains performance stability in pH 3-11 environments, -50℃~+60℃ temperature ranges, and after 3000 hours UV exposure.
