HDPE Lining


Preserve Water for Future Generations: Water Retention Works that Withstand the Test of Time
High density polyethylene is the membrane of choice for long lasting water retention and irrigation works.

Generally less complex than other types than other geotechnical works, retention, irrigation and rain water protection works still require geomembranes that must meet specific criteria.

Continually exposed, in whole or in part, to the sun, the polyethylene must be capable of withstanding ultraviolet rays. Installed in conditions that can be made more different by wind, dust, harsh nature, rough, uneven or unstable terrain, the geomembrane must withstand potential perforation and return, over the long term, the benficial properties for which it was selected.
