Reinforced UltraTech Flexible Geomembrane

 


Excellent Weatherability & Chemical Resistance

The following is a specification for EPI's Reinforced UltraTech geomembrane and is recommended for use as a guideline in specifying lining and cover membrane.

UltraTech is a polymeric lining material made from a synthetic compound formulated with polymers, resin modifiers and stabilizers. UltraTech is noted for its high tensile strength and flexibility over a broad temperature range. It offers excellent weatherability and chemical resistance.

The Reinforced UltraTech flexible membrane provides high dimensional stability through its three-layer construction: two layers of UltraTech with a scrim fabric sandwiched between. It is manufactured totally by calendering, with each ply laminated to the next ply through the openings in the scrim weave to produce a pinhole-free membrane.

The open-weave supporting fabric has a 16 x 8, 2:1 leno weave 250 warp/500 fill denier (8 x 8 - 500d apparent) construction. The single ply of supporting fabric is totally encapsulated within the 2 plies of membrane, giving a 3-ply construction of nominal 35 mil thickness.


Benefits of Reinforced UltraTech:

  • Weather resistance: Does not require earthen cover.
  • Resistant to petrochemicals.
  • Flexibility for three dimensional performance.
  • Large panels eliminate field seams
  • Custom size and shape panels.

 

Typical Applications:

  • Exposed Applications
  • Hydrocarbon Resistant
  • Industrial Waste
  • Oilfield
  • Secondary Containment
  • Remediation
