Polyethylene Geomembrane Description
Geomembranes, often referred to as geomembrane liners, are impermeable membranes used in conjunction with rocks or earth to block fluid migration in man-made structures. These geomembranes are usually made of synthetic polymers in sheets ranging from 0.2 to 2.0 mm thick. Geomembranes are made of various materials such as Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE) and Polypropylene (PP). Due to their ability to block fluids, they can help to prevent the dispersal of contaminants, and may be used with soil liners or permeable geotextiles to create a composite lining system that provides added security.

Polyethylene Geomembrane Application
Geomembranes are being used in environmental, hydraulic, transportation, and oil and gas applications as well as the waste industry. The most common type are the continuous polymeric sheets. When larger geomembranes are needed, they are thermally or chemically melted together at the seams for strength and durability. The size of the geomembrane is completely customizable, so they are can be as small as a backyard fish pond or as large as a football field if necessary.
Geomembrane work is very useful when dealing with dams. Seepage control is just one use for geomembranes. They can be used when working with canals, reservoirs, storage basins, dams, and tunnels. In Europe, geomembranes have been used to repair old concrete and masonry dams.
