HDPE Dam Liners for Water Containment Project in Chile

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.

Specifications of HDPE Dam Liners for Water Containment Project  in Chile

• Dam liner Thickness – 1.0mm
• Composite geomembrane – 2.0 mm
• Specification – 7m×200m

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.

HDPE Dam Liner for Dam Construction in Vietnam

HDPE dam liner is one of the more popular materials used in the fabrication of these plastic lined reservoirs. HDPE dam liner is prepared from ethylene by a catalytic process. BPM HDPE dam liner is the most widely used geomembrane in the world and is used more commonly internationally due to its availability and relatively low material cost. HDPE pond liner is an excellent product for large dam applications that require UV and ozone resistance, chemical resistance or high quality installations. The HDPE smooth geomembrane is delivered in large rolls and may be heat welded in the field by trained technicians. HDPE dam liner has been used in landfills, wastewater treatment lagoons, animal waste lagoons, mining applications and for water storage.

In the world today, there is a big shortage of potable water for domestic use as well as agricultural water for irrigation and this has led to much suffering for many people in the world. The most important factor that undermines the availability of water is the prohibitive cost of water storage structures. In systems that depend on rainwater harvesting for example, water security and availability lies squarely on how much water one can store. As the commencement of the rains is unpredictable, it is therefore important for water users to collect as much water as they can during these short rainy seasons and store it for use in times when there is no rainfall.

Our Vietnam customer sent us an inquiry on HDPE dam liner for dam construction project. We decided to use 0.8mm HDPE dam liner for dam project by our negotiation. The Vietnam customer was satisfied with BPM HDPE dam liner production process, raw materials and product quality. In addition, we quoted them very competitive price. Finally, he signed the supply contract and construction service agreement. Soon afterwards, our company sent a professional HDPE dam liner welding technician to the site to assist in welding. Finally, he confirmed the quality of our lake liner, then he signed order with us.
