HDPE Durability

High Density Polyethylene (HDPE) Geomembrane has been widely used in sewerage and water containment since the 60’s. One concern is the long term durability, particularly in UV exposure condition. We are planning to evaluate the performance of some of these liners on a few of our work as early as 1993, under fully UV exposed condition, by retrieving the membrane for tensile strength and OIT testing. It is hoped that we have an indication on the properties changes over the years.
