Details of Geomembranes

       Geomembranes are impermeable membranes used in conjunction with rocks or earth to block fluid migration in
man-made structures. In most cases, they are made of synthetic polymers. Unlike other methods of controlling fluid
movement, such as using clay, asphalt, or sand stabilized with cement, these membranes have almost no permeability
if there are no holes in the material. Due to their flexibility, they can accommodate ground settling and shifting.
Geomembranes may also be called synthetic liners, polymeric membranes, or flexible membrane liners.

       Geomembranes are most often made of polyvinyl chloride (PVC), medium-density polyethylenes, chlorosulfonated polyethylene, or a similar kind of material. Due to their ability to block fluids, they can help to prevent the dispersal of
contaminants, and may be used with soil liners or geotextiles to create a composite lining system that provides added
security. Geotextile fabrics, made from polyester or polypropylene, are used with soil to provide filtration, reinforcement,
or drainage in many civil engineering applications such as embankments, canals, and railroads.
Applications 
Geomembrane applications:
        .Sanitary project(Landfill,sewage treament,toxic and hazardous compounds disposal)
        .Water conservancy(river,lakes water reservior dam seepage control)
        .Construction projects(subway construction, roof garden, sewage pipe liner)
        .Lanscape Works(artificial lake, pool)
        .Agriculture engineering(reservior, drinking water tanks, water storage pond, irrigation system)
        .Transportation(railway,highway) 
      
Installation

       When preparing an area for geomembrane installation, the soil must be freed of all sharp objects such as sticks that
could puncture the lining; if necessary, geotextiles can be placed below to reduce the risk of tears. Panels of geomembrane lining are usually bonded at adjacent seams, using extrusion welding, hot-wedge seaming, or hot-air welding. Generally,
hot-air welding is used as a temporary measure to immobilize the lining before an extrusion weld is applied. Seams are subsequently tested to ensure that there are no leaks and that they are properly joined.
