The liner’s job is to keep leachate, the contaminated liquid that forms as waste decomposes and rainwater percolates through it, out of the soil and groundwater below. Ocean also supplied and installed 6,500 sq m of Ocean Non Wovens Geotextile as the liner’s protection layer. ## Project overview - **Project Type:** Landfill Project - **Client:** Visiontek Consultancy Services - **Location:** Odisha - **Products Supplied & Installed:** Ocean HDPE Liner 1500 Micron; Ocean Non Wovens Geotextile - **Quantity:** 6,720 SQM of HDPE liner; 6,500 sq m of geotextile - **Scope:** Supply and Installation - **Application:** Environmental containment and leachate control The landfill needed a barrier that would stop leachate migrating out of the cell and stay durable for the life of the site. Odisha gets heavy south-west monsoon rain, so the lining also had to cope with wet ground, rainfall interruptions during installation and the larger leachate volumes that follow a wet season. ## Why landfills are lined with HDPE geomembrane Leachate typically carries dissolved organic compounds, ammonia, heavy metals and pathogens. Once it reaches an aquifer it is slow and expensive to clean up, so the barrier layer is the part of a landfill that cannot be allowed to fail. An HDPE [geomembrane](https://oceangeosynthetics.com/products/ocean-geomembrane/) is the standard material for this layer because it combines: - Extremely low permeability - Resistance to the wide range of chemicals found in leachate - Good puncture resistance at landfill thicknesses - Long-term durability - UV stability from carbon black - Environmental stress crack resistance A compacted clay liner on its own depends heavily on how consistently it was compacted in the field, and it can crack if it dries out. A welded HDPE sheet gives containment performance that can be measured and tested seam by seam. In practice the two are usually combined: Indian practice for municipal solid waste landfills (the Solid Waste Management Rules, 2016 and the CPHEEO manual) specifies a composite barrier: an HDPE geomembrane of at least 1.5 mm over a compacted clay or amended soil layer with a permeability no greater than 1×10⁻⁷ cm/s, beneath a leachate collection layer. ## Why a 1500 micron liner 1500 micron is 1.5 mm, the minimum geomembrane thickness in Indian MSW landfill practice. Thinner grades are used for ponds and low-risk containment, but a landfill liner faces: - Sharp objects in the waste and the drainage aggregate above it - Settlement as the waste decomposes - Many metres of waste loading for decades - Leachate whose chemistry changes over time - Mechanical stress from construction traffic and cover placement A thicker sheet gives more resistance to puncture and tear, more margin against slow stress cracking, and more thickness to lose before antioxidants and ageing become a concern. GRI White Paper #6 from the Geosynthetic Institute (Koerner, Hsuan and Koerner) estimates that a covered HDPE geomembrane made to GRI-GM13 lasts many decades, with service life falling as the burial temperature rises. ## The geotextile cushion layer Ocean also supplied and installed 6,500 sq m of [Ocean Non Wovens Geotextile](https://oceangeosynthetics.com/products/geotextile-manufacturers/) as the protection, or cushion, layer of the composite liner. A 1.5 mm sheet resists puncture well, but in a landfill it sits under drainage aggregate, waste and heavy compaction plant, and a single stone pressed into it under that load can open a leak. A thick needle-punched non woven placed against the geomembrane spreads those point loads so they do not concentrate on the sheet. In landfill lining practice the protection geotextile is selected by testing it with the geomembrane under the expected load and the actual drainage stone, rather than by mass per unit area alone. It should be laid with overlaps or seams so no gaps open when the stone is spread, and the cover is placed by pushing material forward from already-covered areas so plant never runs on the bare layers. ## What has to go right during installation ### Subgrade preparation A good geomembrane can still be damaged early if it is laid over sharp stones, construction debris, uneven surfaces or poorly compacted soil. The subgrade has to be inspected, graded and prepared before the liner is deployed. ### Weather Heat makes the sheet expand, and sudden rain stops welding, because seams cannot be made on wet or dirty sheet. Installation is scheduled around these windows. ### Thermal expansion and contraction HDPE expands and contracts noticeably with temperature. If installers do not allow for this movement, the sheet wrinkles in the afternoon heat and pulls tight (“trampolines”) at corners and toes when it cools, both of which concentrate stress. ### Seam welding The seams are the weakest point of any geomembrane system, and a small welding defect can become a leakage path. Field welding needs trained technicians and strict quality assurance. ## Quality control on a landfill liner Containment depends on installation quality as much as on the product. Quality assurance on a landfill liner typically includes: - Trial seams welded and peel/shear tested before each welding session - Vacuum box testing of extrusion welds and patches - Air pressure testing of double hot-wedge seams - Visual seam inspection - Thickness verification - Subgrade inspection and sign-off - Material traceability documentation (roll numbers to panel layout) ## Long-term performance Once the cell is filled, the liner has to keep working while the landfill changes around it. Waste settles as it decomposes, so the lining must take that movement without tearing. Leachate chemistry shifts over the years. Poor drainage can build hydrostatic pressure above or below the liner, which is why the leachate collection layer and any groundwater relief below matter as much as the sheet. Exposed sections on side slopes and anchor trenches rely on the carbon black for UV resistance and should be inspected periodically. The same considerations apply to other HDPE containment: aquaculture ponds, reservoirs, irrigation ponds, wastewater lagoons and industrial containment. In water storage, a liner stops seepage losses and keeps the water out of contact with the soil, which makes water levels and quality easier to manage. Ocean also supplies [geosynthetic clay liners](https://oceangeosynthetics.com/products/geosynthetics-clay-liner/) and [drainage geocomposites](https://oceangeosynthetics.com/products/geo-composites/) for the other layers of a landfill lining system. On this Odisha landfill it supplied both: see the [6,798 sq m of Ocean Geosynthetic Clay Liner 6 mm](https://oceangeosynthetics.com/geosynthetic-clay-liner/) and the [6,700 sq m of Ocean Drainage Geocomposite 5.5 mm used for leachate drainage](https://oceangeosynthetics.com/drainage-geocomposite-55-mm/). ## About Ocean Non Wovens Ocean Non Wovens manufactures and supplies [geosynthetics](https://oceangeosynthetics.com/category/geosynthetics/) across India for [waste management](https://oceangeosynthetics.com/suitable_sectors/waste-management/) and landfill projects, aquaculture developments, reservoirs, irrigation systems and industrial containment.
