General characteristics: 

  • Longevity: excellent performances over time,
  • Compatible with all types of materials (concrete, steel, PVC, etc) by sealing or gluing,
  • Only one layer is efficient and no need a protective layer or geogrid.

Easy to install

  • Compatible with all climates, even extreme ones : from -40 °C to +40°C,
  • Does not lift in the wind due to its mass (2.5 – 6.4 kg/m²),
  • Compatible with immersion installation and underwater jointing,
  • Limited number of welds due to wide rolls (5.10 m),
  • Installation on natural substrates, flexibility to adapt to soil, excellent manning coefficient,
  • Easy to install, without specific equipment by local team.
