Geomembrane sheet
UV resistant
Fully resistant to most chemical compounds and alkalies
The low weight and big width of the rolls enable an efficient performance of the works
Perfect for protection from aggressive chemicals, including petroleum and animal compounds
Very resistant to tearing
Does not biodegrade
Environment-friendly
Long durability – once applied, it works for many years
High-density polyethylene impermeable geomembrane sheet (HDPE) are resistant to most chemicals and have a high-stress factor resistance. These tried and tested products are ideal for applications including attenuation tanks, pond lining, anaerobic digestion applications, containment, cut-off trenches and structural waterproofing.

Benefit
1. Excellent Waterproofing & Anti-seepage
Geomembrane provides an effective barrier against liquid leakage and gas migration.
It ensures reliable containment in ponds, landfills, mining sites, and reservoirs.
2. High Chemical & UV Resistance
Made from high-quality HDPE or LLDPE, geomembrane resists acids, alkalis, and various chemicals.
It also withstands long-term exposure to sunlight and harsh weather conditions.
3. Outstanding Mechanical Strength
Geomembrane has high tensile and puncture resistance, allowing it to maintain integrity even under large deformations or uneven settlement.
4. Long Service Life
With anti-aging and antioxidant additives, geomembrane can last over 20 years in exposed applications and more than 50 years when buried.
5. Easy Installation & Welding
Lightweight and flexible material makes it easy to transport and install.
Seams welded by hot wedge or extrusion welding are stronger than the base material itself.
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
