HDPE Geomembrane

Phone:18053450611
HDPE GeomembraneIt is one type of geosynthetic material. The application of geosynthetic materials originated in the 1950s. In China, the domestic geomembrane was part of the 1985 Plan. HDPE geomembrane is a waterproof and barrier material produced from (medium to) high-density polyethylene resin (with a density of 0.94g/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. Highly resistant to burial and corrosion, the structure is fluffy with excellent drainage properties.

4. Excellent coefficient of friction and tensile strength, with geosynthetic reinforcing properties.

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

6. Adaptable to uneven subgrades, resistant to constructional forces, and with low creep.

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

8. Designed for permeable materials, it boasts excellent anti-filtration and isolation properties, strong puncture resistance, and thus, excellent protective performance.

Function and Application:
Primarily used for applications such as landfill, wastewater treatment, water conservancy, agriculture, transportation, high-speed rail, tunnels, airports, buildings, and landscape waterproofing pads.

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, do not pull too tightly, and leave a 1.50% allowance for local settling and stretching. Considering the actual conditions of this project, the slope is laid in an order from top to bottom.

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

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

4. First the slope, then the field bottom.
5. During slope laying, the direction of the film should be generally parallel to the line of the steep slope.

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