Geomembranes

A geomembrane is very low permeability synthetic membrane liner or barrier used to limit the movement of liquid or gas. The range of geomembranes available to the end user is extensive and includes HDPE, LLDPE, PVC and bitumen impregnated to name a few. Each generic alternative has their own unique characteristic which requires specific test characteristics.
