Benefits of HDPE
The most chemically resistant member of the polyethylene family due to its dense configuration.
Field welded with hot wedge welders and extrusion welders. These factory quality welds are virtually stronger than the sheet itself.
The best QC-QA testing capabilities in the marketplace.
No need to cover the liner because it is UV stable = cost-effective.
Available in roll stock and come in varying thicknesses ranging from 20 to 120 mil depending on your requirements.
Applications
Passive, self-activating secondary containment liner system best suited for containment around the transformer, rather than the perimeter of the substation
Perfect solution for transformers (live and spare), tank storage, wind farms and solar fields
For a smaller footprint, use corrugated HDPE pipe with the containment system to increase the void space
Use geomembrane liner to line chipped or cracked concrete containment
