ISO HDPE Impermeable Geomembrane for Pond Landfill and Tunnel

Geomembrane Introduction

Our high density polyethylene (HDPE) geomembranes provide an impermeable barrier against a wide range of solids and liquids. They exhibit excellent chemical and UV resistance,impermeability, and high yield and welded seam strengths, which is widely used as the liner.(model according to the thickness of distinction, different thickness and different price) production capacity: thickness:0.1 mm  -6 mm, width: 1-8 meters. It is suitable for seepage control in special industries, and is widely used for aquaculture, seepage control, reservoirs or sewage treatment ponds.

Construction Method

1. The slope shall be laid in order from top to bottom. Don't pull it too tight.
2. Tow adjacent longitudinal joints should not be in a horizontal line, should bestaggered more than 1m each other.
3. Longitudinal joints should be more than 1.50m away from the dam foot and bending foot, and should be located on the plane.
4. When the slope is laid, the direction of spreading film should be basically parallel to the slope line.
5. The construction, first of all to use small diameter sand or clay levelingbase, and then laid the geomembrane. The geomembrane should not be stretched too tight, and the part of the soil bured at both ends is corrugated. A transitional layer of about 10cm is laid on the geomembrane with sand or clay.
