The geomembrane acts as the water barrier: it stops stored water seeping out through the reservoir bed and embankments, and keeps impurities in the surrounding ground from getting into the water. **Product:** HDPE Geomembrane 62825 sq mtr **Location:** Telangana Reservoir Dam ## Problems Seepage and leakage are long-running problems for reservoirs and small dams. Water lost through the bed and embankment is water that never reaches the fields or the taps, and seepage that carries soil with it (piping) can weaken an embankment over time. The reservoir in Telangana needed a new lining system to replace its traditional arrangement. The main issues were water seepage and the ingress of impurities into the stored water, including by-products of industrial waste and minerals from the surrounding ground. Severe floods and stronger storms were adding to the strain on the dam and the areas around it. The owners needed a lining with very low permeability and enough strength to last. Much of Telangana is semi-arid and depends on stored monsoon water through the dry months, so every cubic metre held in a reservoir counts. ## Solutions An HDPE [geomembrane](https://oceangeosynthetics.com/products/ocean-geomembrane/) is a continuous polyethylene sheet with extremely low permeability. Welded into one barrier across a reservoir bed and its slopes, it cuts seepage to negligible levels through intact sheet, and acts as a hydraulic barrier between the stored water and the ground beneath. The properties that make HDPE suit reservoir lining: - **Very low permeability:** holds water and blocks migration of dissolved contaminants into or out of the reservoir. - **Strength and flexibility:** resists puncture and tear, and follows minor settlement of the bed and embankment without cracking. - **Chemical and weathering resistance:** inert to the salts and minerals in water and soil, and carbon-black stabilised against UV on exposed slopes. - **Durability:** a well-installed, covered liner has a long service life. A geomembrane is a barrier, not a filter. Where a filtration or cushioning layer is needed, for example over a stony subgrade or beneath a soil or concrete cover on the slopes, a non-woven [geotextile](https://oceangeosynthetics.com/products/geotextile-manufacturers/) is used alongside it. ## Installation On a reservoir lining of this size, the bed and slopes are trimmed and cleared of sharp stones, a cushion geotextile is laid where needed, and the HDPE panels are deployed down the slopes and welded by double hot-wedge, with seams air-pressure tested. The liner is locked into anchor trenches at the crest, and slopes are checked for interface friction so the liner and any cover stay in place when the reservoir is drawn down. Sheet rate is only one line in a reservoir budget. Our guide to [budgeting a lined pond or reservoir](https://oceangeosynthetics.com/how-much-does-geomembrane-cost/) lists the other cost heads, from protection layers and welding to seam testing and anchor trenches, with an illustrative quantity take-off. ## **FAQs** ### **What is the difference between smooth and textured geomembranes**? Smooth geomembranes have a smooth surface, while textured geomembranes have a roughened surface that grips soil and geotextiles. Textured sheets are used on steeper slopes where the friction angle and interface shear strength of a smooth sheet are not enough to keep the liner and its cover in place. ### **Are geomembranes resistant to chemicals?** HDPE geomembranes resist a wide range of chemicals. The specific resistance depends on the material type and the chemicals involved, so compatibility tests (for example ASTM D5747) should be performed for unusual liquids. ### **Can geomembranes be used in high-temperature applications?** Yes, with care. Higher temperatures reduce a geomembrane’s strength and shorten its service life, and the effect is large for polyethylene. For hot liquids, check the manufacturer’s temperature limits and lifetime data before selecting a material and thickness.
