Geotextile membrane

Product Introduction:
HDPE GeomembraneIt is a type of geosynthetic material. The application of geosynthetic materials originated in the 1950s. In China, the domestic geomembrane was one of the projects under the Eighth Five-Year Plan. HDPE geomembrane is a waterproof barrier material produced from high-density (or medium-density) polyethylene resin (with a density of 0.94 g/cm³ or higher).

Performance Features:

1. Free from chemical additives and heat treatment, it is a type of building material.

2. Excellent mechanical properties, good permeability, and resistance to corrosion and aging.

3. High resistance to burial and corrosion, with a fluffy structure and excellent drainage properties.

4. Offers excellent coefficient of friction and tensile strength, with geosynthetic reinforcement properties.

5. Features include isolation, anti-filtering, drainage, protection, stabilization, and reinforcement.

6. Adaptable to uneven subgrades, resistant to construction force damage, and with minimal creep.

7. Good overall continuity, lightweight, and easy to install.

8. Being permeable materials, they offer excellent anti-filtration isolation and strong puncture resistance, thus providing great protective performance.

Application:
Primarily used in anti-seepage lining projects for landfill, wastewater treatment, water conservancy, agriculture, transportation, high-speed rail, tunnels, airports, buildings, and landscapes.

Construction Plan Specifications:

Do not drag or pull the geotextile membrane roughly during transportation; avoid sharp objects piercing it.

1. Extend from the bottom to the top, avoiding excessive tension. Retain a 1.50% allowance for local sinking and stretching. Considering the actual conditions of this project, the slope should be laid from top to bottom.

2. The vertical joints between adjacent panels should not be aligned in a single horizontal line; they should be staggered by more than 1 meter.

3. Vertical joints should be located more than 1.50m above the dam foot and bend corners, and should be set on a flat surface.

4. First the slope, then the base of the field.
5. When laying on the slope, the direction of the film should be essentially parallel to the steep slope line.

Product Specifications:
0.3mm to 3mm thickness, width from 1m to 8m, length as per customer's requirement.
