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 of a synthetic compound formulated with polymers, resin modifiers, and stabilizers. UltraTech is highly trusted for its high tensile strength and flexibility over a wide range of temperatures. It provides exceptional resistance to weather and chemicals.
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 UltraTech 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-resistant (does not require an earthen cover)
Three-dimension performance flexibility
Large panels, which eliminate field seams
Custom size and shape panels
