Technical Notes
HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.
Installations are temperature and poor weather sensitive.
40 mil HDPE liner requires extra effort to ensure that the subgrade is in excellent condition. It is suitable as an upgrade from products like the 20 mil RPE for larger installations and is an excellent secondary containment liner on multi-layer systems (for example; subgrade, geotextile layer, 40 mil
HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)
60 mil HDPE liner is the staple of the industry and is suitable for most applications.
80 mil HDPE liner is a thicker design for more aggressive subgrades.
HDPE Lining materials are a cost effective choice for exposed lining projects because the geomembrane is UV stable and requires no soil cover. This product has been used in landfills, WWT lagoons, animal waste lagoons and mining applications due to its high chemical resistance. HDPE geomembrane can be bonded via a wedge weld or fusion weld to create a strong and seamless system. The range in available thicknesses, from 40 mil to 120 mil, allow the technology to suit many applications.
