Geomembrane, geosynthetic material, is a gas, fluid and humidity barrier. Geomembrane sheets can be installed side by side and connected to each other with thermal welding. Though not 100% impermeable, geomembrane sheets are considered impermeable compared to geo-textiles, soils, and even clay.
Geomembrane sheets are either based on Polyethylene (LLDPE, HDPE, and VLDPE) or PVC. Among these HDPE is the most common due to its desirable properties, such as ample supply, high resistance against UV light, chemicals, cracks in tough environments (ESCR), high flexibility, good welding ability, and ultimately, low costs.
Padena Polymer produces HDPE Geomembrane compounds according to USA’s Geosynthetic Research Institute (GRI) GM-13 Standard.
