Polyethylene Geomembrane
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.
