Geomembrane are impermeable synthetic membrane sheets made ​​from High Density Polyethylene [HDPE] or Linear Low Density Polyethylene resins. These products are commonly used in geotechnical engineering work and are suitable for applications requiring a material with chemical resistance and good durability. With the stabilization of UV protection, Geomembrane have the ability to be resistant to UV, chemical effects, acid, alkali and corrosive salt. Geomembrane are also resistant to the influence of fungi, micro-organisms and can not be penetrated by plant roots.
