The popularity of High Density Polyethylene (HDPE) is primarily
due to its low initial material cost and excellent chemical
reistance. This allows thicker sections to be used compared to
other geomembrane materials. A thick, durable, HDPE liner can be
placed in exposed applications where the cost of other materials
would be prohibitive. HDPE has excellent chemical resistance
which is often the driving force behind the selection of HDPE.
HDPE is a field assembled lining material that cannot be
practically fabricated in the shop. All HDPE projects,
regardless of size, must be installed by trained installers.
HDPE is a versatile material which is used widely across all
applications. One of the main uses of HDPE is for landfill base
liners where its chemical resistance is used to good effect.
HDPE can also be used in a multitude of secondary containments,
pond linings, and water containment projects. HDPE is best used
as an exposed lining material, and has the UV resistance
required for many years of outstanding
