HDPE composite geomembrane
1.Introduction
Geomembranes have a very low coefficient of permeability much lower than most clays and natural soils.
HDPE, in particular, is highly resistant to any form of chemical or biological attack.
It is also very resistant to U.V. degradation. Many geomembranes are so inert that they cannot be glued
together the chemical reactions of adhesives do not work on them−they have to be welded together by heat.
Their inert nature and long life characteristics make HDPE geomembranes ideal to act as liners for liquid
chemical reservoirs, fresh−water reservoirs, animal waste containers, basal linings and top capping layers
for waste disposal sites.
During installation, HDPE geomembrane edges are sealed to one another with a double heat welded joint.
The gap between the two welds is checked for leakage using an air pressure test.
