Types of Geomembrane
Geomembrane is a very low permeability synthetic membrane barrier , sheet , or liner used within soils so as to control fluid (liquid or gas) migration in a human-made project, structure, or system. Depending on the parent resin used, several types of geomembranes are available. The most commonly used geomembranes are listed below. Geomembrane ► HDPE Geomembrane High-Density Polyethylene (HDPE) is characterized by strong UV/temperature resistance, inexpensive material cost, durability, and high resistance to chemicals. It is the most commonly used geomembrane because it offers higher thickness which other geomembranes don’t. HDPE is the preferred choice for pond and canal lining projects, landfill, and reservoir covers. Thanks to its chemical resistance, HDPE can be used in storing potable water. ► LLDPE Geomembrane LLDPE (Linear Low-Density Polyethylene) geomembrane is made with virgin polyethylene re...
