HDPE dam liners are the kind of ideal anti-seepage geosynthetic products widely used for reservoir projects to contain water. BPM HDPE dam liners are made from high grade polyethylene raw materials, adding carbon black and antioxidant, anti-aging, UV-resistance components. BPM HDPE geomembrane liner is not only suitable for fish or shrimp farming pond in aquaculture but also can be used for dam projects. Our high quality HDPE dam liners feature 100% virgin material, smooth surface and high tensile strength, higher break elongation, excellent performance in mining, dam, landfill projects and its service life can reach more than 20 years.
Our Chile customer ordered HDPE dam liner for his dam project. The dam water containment project mainly considered the depth of dam and puncture resistance of the HDPE dam liners to contain water. And to make sure the break strength and puncture resistance of the Dam liner, we also advised client to avoid the closer pieces welding together and decrease the welding T area during installation. And for future projects consideration, depth more than 30m need to use composite geomembrane liner to increase the ability to undertake water pressure. The dam project will begin in March, 2019. We recommended that the 1.0mm smooth HDPE dam liners and 2.0 composite geomembrane might be cost-effective for the project, meanwhile, we sent him the high density geomembranes samples. After communication and negotiation, finally, he confirmed the geomembrane quality and signed order contract with us.

The dam project is a sloping wall earth-rock coffer dam structure with plastic dam linings, and the corpuscle is closely combined with the dam. The dam crest has an elevation of 56 meters and the maximum dam height is about 16.5 meters. The HDPE dam liner and the concrete cutoff wall are used for seepage prevention. The maximum anti-seepage height of HDPE dam liners are about 11 meters. The dam foundation adopts concrete anti-seepage wall and curtain grouting anti-seepage. The dam body anti-seepage wall construction platform has an elevation of 28 meters, the water-facing aspect ratio is 1:2.5, and the back-water slope ratio is 1:1.9. The lower part of the composite geomembrane is 20 cm thick cushion material and 2 m thick transition material. The top of the dam is made of C30 concrete pavement with a thickness of 30cm and a 20cm thick gravel cushion. The dam liner welding and installation process were guided by BPM engineers.
