Geomembrane HDPE Sheet

 

Application

The  geomembranes provide a complete seal against even the most toxic substances. It  is typically used in

1. sealing applications for landfill base seals as well as caps,

2. environmental sealing applications for the protection of groundwater from contamination,

3. in water conveyance structures, canals or ponds.

Features 1.  Versatile sealing applications possible2.  Excellent chemical resistance due to selected raw materials3.  Extreme high elongation during uni-axial and multiaxial deformation4.  High stress cracking resistance5.  Very high UV-resistance6.  Direction independent shear stress transfer with structured surfaces7.  High interface friction angles with embossed structured surfaces8.  Slope dependent structured surfaces available for project specific designs9.  Complete quality control from the resin to the final product

10. High Melt Flow Index allows an excellent welding performance11. Smooth edges with removable plastic tape for clean welding surface and overlap lines12. ISO 9001: 2000 certified
