Water pond liner is often the high quality smooth geomembrane HDPE liner which is widely used as part of the anti-seepage system for modern water containment application. The main mechanism is to block the water leakage channel of the earth by the impermeability of the water pond liner, then to withstand the water pressure and adapt to the deformation of the dam with its large tensile strength and elongation. Water pond liner is the ideally anti seepage geosynthetic material for water containment applications due to it excellent chemical resistance, outstanding stress crack capacity, lowest permeability, excellent UV resistance and stable low temperature embrittlement resistance. BPM brand water pond liner is fabricated by the state of the art automatic geomembrane production lines and advanced three layered pressing technology in accordance with GRI GM13 standard. , so it can be used in unconventional temperature environment.
Water containment facilities like storage reservoirs, artificial lake and canals need reliable and durable protection from leakage because seepage is the main factors causing water loss. HDPE geomembrane is increasingly used in the landfill liner systems because they can tolerate large deformation. The use of a water pond liner prevents contaminants from entering groundwater sources or streams. In addition, it conserves potable water resources by preventing seepage.
Our Greece customer wanted to order water pond liner for his water containment project. He contacted us and asked us about the water pond liner specifications and the installation guide. The Greece customer was satisfied with BPM water pond liner production process, raw materials and product quality. In addition, we gave him the water pond liner with very competitive price. Finally, he signed the supply contract and construction service agreement. Soon afterwards, BPM sent a professional HDPE pond liner welding technician to the site to assist in welding. Finally, he confirmed the quality of our HDPE water pond liner, then he signed order with us and paid for the deposit.

How to install Water Pond Liner for Containment Applications
1 Basic Work
1.1 After the foundation shape and excavation, the slope shall be cut, leveled or compacted. Displacement and backfilling of disturbed soil shall be layered and sprinkled with water or compacted, and the thickness of each layer shall be greater than or equal to 400mm.
1.2. Remove materials with punctured hidden dangers such as bricks, stones, and tiles; glass and metal debris; branches, plant roots, etc. Clean up the obstacles in the field and provide the necessary laying conditions.
1.3. The surrounding retaining wall, pump pit, bridge foundation, and installation and reservation of underwater nozzles must be completed before the construction of composite geomembrane.
2 Water Pond Liner Welding Process
2.1 Weld lap width: 80~100mm; natural pleats of plane and vertical surface are 5%~8%; reserved expansion and contraction: 3%~5%; residual amount of scrap: 2%~5%.
2.2 Hot-melt welding working temperature is about 280 ~ 300 °C or so; travel speed is about ~3m/min; welding form is double weld.
2.3 Damage repair method: cut the same material, hot melt adhesive, polyethylene seal.
2.4 There is no imitation connection at the weld bead, and mechanical stitching is used.
2.5 The sealing of the underwater nozzle is stopped by GB rubber sealing strip, metal bandage and anti-corrosion treatment.
3 Deployment Process
3.1 The laying and unwinding direction of the smooth geomembrane is carried out from E to W or from W to E. The height of each laying length, including the height of the water retaining walls on both sides, is completed once. 2 laying sequence, from the channel axis to the S, N sides.
3.2 Construction process, first make the mortar protective layer (20-30mm) of the composite geomembrane at the bottom of the lake, and then do the paste with the vertical retaining wall.
3.3 Combination process of water pond liner and retaining wall. The adhesive is applied to the adhesive surface of the HDPE geomembrane and the retaining wall, and the drying is allowed to stand for about 5 minutes, and then pasted, extruded, and flattened. The adhesive is made of asphalt latex paint, cement and water. After the paste is completed, the nails are anchored above the water level line, and waterproof and anti-corrosion treatment is performed.
