The liner was used as a [geomembrane](https://oceangeosynthetics.com/products/ocean-geomembrane/) barrier within the pavement and drainage system, to keep water out of the pavement layers and subgrade and to contain fuel and other fluids where they could otherwise reach the soil. ## Why water control matters on an airfield Airfield pavements carry heavy, repeated wheel loads from landing and taxiing aircraft. They depend on a firm, dry subgrade. When water gets into the pavement layers or the soil beneath, the subgrade softens, loses bearing capacity, and the pavement above cracks and deforms. Areas around aircraft maintenance and refuelling also see spills of aviation fuel, lubricants and hydraulic fluid, which should not reach the ground. An HDPE geomembrane addresses both problems. Its very low permeability stops water and fluids passing through, it has good tensile strength for its weight, and polyethylene resists hydrocarbons and most industrial chemicals. ## What the liner does in an airfield system - **Subsurface drainage:** stops water infiltrating the pavement layers and subgrade, and directs it to the drains. - **Runoff and stormwater control:** keeps drainage paths defined and limits build-up of water pressure under the pavement. - **Fuel and chemical containment:** an impermeable barrier in areas exposed to aviation fuel and lubricants. - **Subgrade protection:** prevents moisture from weakening the soil layers. The geomembrane usually works alongside other [geosynthetics](https://oceangeosynthetics.com/category/geosynthetics/) in an airfield. [Geogrids](https://oceangeosynthetics.com/products/geogrid-manufacturers/) and [geotextiles](https://oceangeosynthetics.com/products/geotextile-manufacturers/) improve load distribution and stabilise weak subgrades, geocomposites carry subsurface water to the drains, and geotextiles protect slopes and embankments from runoff erosion. ## Site challenges at Gwalior - **High dynamic loads:** repeated aircraft landing and taxiing create stress concentrations in the pavement and subgrade. - **Water accumulation:** poor drainage leads to subgrade softening, pavement cracking and lower load-bearing capacity. - **Subgrade variability:** uneven soil conditions cause differential settlement, deformation and shorter pavement life. - **Chemical exposure:** aviation fuel spills and hydraulic fluids, against which HDPE gives a chemically resistant barrier. ## Installation and quality control A thin geomembrane only performs if it is installed without damage and with sound seams. **Subgrade preparation:** remove sharp objects and debris, compact to a uniform, smooth surface, and grade to the drainage falls. **Liner placement:** deploy panels without wrinkles, keep them aligned with the drainage design, and avoid laying or welding in a way that locks in thermal stress. **Seaming:** join panels by hot-wedge or extrusion welding, run trial welds before production welding, and check seams by visual inspection and non-destructive testing. **Protection:** use cushioning layers such as nonwoven geotextiles, keep construction traffic off the exposed liner, and place overlying layers in a controlled way so they do not puncture or drag the sheet. Poor seams or a badly prepared subgrade are the usual reasons a liner underperforms. ## Long-term performance and maintenance - **Low permeability:** blocks water and chemical infiltration. - **Tensile strength:** withstands construction and service stresses. - **Chemical resistance:** to hydrocarbons and industrial chemicals. - **UV stability:** carbon black lets the sheet tolerate exposure during construction. Once buried beneath the pavement, an HDPE liner is shielded from sunlight and heat, the main drivers of polyethylene ageing, so its service life is long. Keeping water and spilled fluids out of the subgrade means fewer water-related pavement failures, less rehabilitation work and a pavement that stays serviceable for longer. Ocean Non Wovens manufactures HDPE geomembranes and supplies them with on-site technical support for infrastructure projects across India, from drainage systems to containment.
