HDPE Geomembrane Dam Liner Sheet

HDPE Geomembrane Dam Liner Sheet

What It Is

An HDPE geomembrane sheet for dam and reservoir seepage control, produced from 100% virgin HDPE resin on our own line. It is offered smooth, single textured or double textured, in thickness from 0.2 mm to 3 mm (0.5 mm, 0.75 mm, 1.0 mm and 1.5 mm are the usual dam grades), roll width 1 m to 10 m and roll length from 50 m to 420 m.

What It Does

• Seepage barrier: the continuous welded sheet cuts the flow path through the embankment and the reservoir floor, so storage loss and under-seepage are controlled.
• Grip on slopes: the textured face raises the friction against the soil and the protective layer, which is why steep dam slopes take the single or double textured grade instead of the smooth one.
• Durability: carbon black gives UV resistance and the sheet resists chemical attack, ageing and puncture once covered by the protective layer.
• Weldable on site: panels are joined by wedge and hot air welding and tested along the seams before flooding.

Where It Is Used

Dam facing and reservoir lining, canal and water conveyance channels, irrigation storage, fish ponds and farm basins, drinking water reservoirs, tailings and evaporation ponds, and landfill cells where the same sheet serves as the barrier layer.
