    Technical Notes

    1. HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.

    2. Installations are temperature and poor weather-sensitive.

    3. 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

    4. HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)

    5. 60 mil HDPE liner is the staple of the industry and is suitable for most applications.

    6. 80 mil HDPE liner is a thicker design for more aggressive subgrades.
