High tensile strength and tear resistance.
Excellent durability.
Outstanding low-temperature stability.
High resistance to leachate
and other chemicals.
Fusion joints are tested during installation, ensuring
no leakage occurs at the seams.
A product extruded and manufactured with a uniform thickness and maximum width of
7m by adding UV stabilizers (carbon black) and antioxidants to high-density polyethylene (density ≥ 0.94).
Due to the topographical characteristics of most domestic landfills, where slopes are steep, this product is designed to integrate HDPE sheets
with bentonite mats for slope stability.
HDPE resin is applied onto the HDPE sheet to provide friction properties without altering its physical characteristics.
This product is manufactured by pre-bonding a protective filter mat to the barrier sheet.
The filter mat prevents movement and flotation under water caused by waves or other conditions, protecting the sheet from damage by riprap.
It also enhances ground adhesion and prevents deformation of the barrier sheet during the dumping of quality soil after installation.
