HDPE smooth geomembrane is one type of geosynthetic material, with its application originating in the 1950s. In China, geomembranes were part of the 8th Five-Year Plan. HDPE geomembranes are a waterproof and barrier material produced from (medium) high-density polyethylene resin (with a density of 0.94g/cm3 or higher).

Properties of HDPE Smooth Geomembrane:

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

2. Features 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. 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 constructional external forces, and has minimal creep.

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

8. As a permeable material, it boasts excellent anti-filtering isolation properties and strong puncture resistance, thereby providing superior protective performance.

HDPE Smooth Geomembrane Applications:

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

HDPE Smooth Geomembrane Construction Scheme Specification

Do not drag or pull the geomembrane 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 settling 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 on 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. 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 request.
