Carlisle's GeoMembranes
   

Reinforced Polypropylene GeoMembrane

Carlisle Reinforced Polypropylene GeoMembrane is a heat-weldable polyester reinforced sheet designed for liners and floating covers. Carlisle's membrane is specifically formulated for long-term use in buried or exposed geomembrane applications. The membrane is based on a UV-stabilized polypropylene copolymer, which does not require either polymeric or liquid plasticizers to maintain flexibility.

Physical properties of the membrane are enhanced by a strong, polyester fabric (scrim) that is encapsulated between the polypropylene based top and bottom plies. The combination of the fabric and polypropylene provides reinforced membranes with high breaking / tearing strength and puncture resistance. The relatively smooth surface of the Carlisle GeoMembrane facilitates production of a total surface fusion weld that creates a consistent, watertight monolithic sheet.

Features:

  • Outstanding heat seamability
  • Outstanding puncture resistance
  • Plasticizer-free, does not contain liquid or polymeric plasticizers
  • Excellent low temperature impact resistance
  • Excellent chemical and environmental stress-cracking resistance
  • Exceptional resistance to solar UV, ozone, and oxidation
  • Low water vapor permeance and water absorption
  • Hot melt extrusion processed (not calendared) for complete scrim encapsulation
  • Warp knitted fabric (not woven) for smooth surface and greater thickness-over-scrim
  • Polyester reinforcing fabric which is resistant to degradation by soil bacteria
  • ANSI/NSF-61 drinking water contact certification (potable grade)

Carlisle Reinforced Polypropylene GeoMembrane is manufactured in two grades; Potable (water) Grade and Industrial Grade. The Potable Grade was tested by NSF International and meets the requirements of ANSI / NSF Standard 61 for Drinking Water System Components - Health Effects.
