Geomembranes, which are 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 membranes are usually made of synthetic polymers in sheets ranging from 0.25 to 3.5 mm thick. Geomembranes are made of various materials such as EPDM (Ethylene Propylene Diene Monomer), Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), 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.
Geomembranes are especially important for waste containment. Our products are manufactured from highly durable materials, often with an expected lifetime of hundreds of years. They are resistant to chemicals and wear so that the passage of time and corrosion does not affect the integrity of the geomembrane liner. Each type of geomembrane material has specific characteristics which affect installation procedures, lifespan, and performance.
