DURA-SKRIM®

DURA-SKRIM 8BBR, 8WB, 12BBR and 12WB consist of two sheets of high-strength polyethylene film laminated together with a third layer of molten polyethylene. The white outer layer (DURA-SKRIM 8WB and 12WB) contains UV inhibitors and thermal stabilizers and the black outer layer(s) contains carbon black to enhance outdoor life. The white outer layer is also designed to reduce heat buildup and condensation. A heavy scrim reinforcement placed between these plies greatly enhances tear resistance and increases service life. DURA-SKRIM’s heavy-duty diamond reinforcement responds to tears immediately by surrounding and stopping the tear.   Nominal 8 mil & 12 mil available.

DURA-SKRIM 8BV and 12BV are available for use in more demanding applications requiring higher tear resistance. Both membranes are designed to withstand long-term outdoor applications requiring up to 5 years of exposure or more depending upon the geographical location of the project.  DURA-SKRIM 8BV and 12BV are designed to meet the requirements of the Geosynthetics Research Institute; GRI-GM22 Standard Specification.  Nominal 8 mil & 12 mil available.

DURA-SKRIM R20DD consists of virgin outer layers of gray high-strength polyethylene film laminated together with hot molten polyethylene. Both outer layers contain stabilizers to assure long outdoor life. A layer of polyester scrim reinforcement placed between these plies greatly enhances tear resistance and increases service life. DURA-SKRIM’s heavy-duty diamond reinforcement responds to tears immediately by surrounding and stopping the tear.   Nominal 20 mil available.

DURA-SKRIM J30, J36 & J45 are Linear Low Density Polyethylene geomembranes reinforced with a heavy encapsulated 1300 Denier polyester reinforcement. In addition to excellent dimensional stability the tri-directional reinforcement provides exceptional tear and tensile strength. Dura-Skrim J-Series membranes are formulated with thermal and UV stabilizers to assure a long service life. Custom colors are available based on minimum volume requirements.  Nominal 30 mil, 36 mil, and 45 mil available.

RUFCO®

RUFCO 610B, 1010B, 2010B and 3010B are mono-layer membranes consisting of a blended linear polyethylene. Carbon black additive provides protection from UV rays and assures long outdoor life.  The Rufco 10-Series membranes are manufactured from virgin and select reprocessed resins to provide an economical solution to many non-critical applications.  Puncture and tear strengths far exceed common polyethylene or vinyl films.  Nominal 6 mil, 10 mil, 20 mil & 30 mil available.

RUFCO 2000B, 3000B and 4000B are mono-layer membranes consisting of a very flexible, linear low-density polyethylene (LLDPE). LLDPE provides high elongation, tremendous tear resistance and bursting strength. A minimum carbon black content of 2.0% provides excellent protection from UV rays and harsh weather conditions. They do not contain plasticizers which can migrate to the surface, causing premature aging. Manufactured from virgin resins, RUFCO 2000B, 3000B and 4000B are designed to provide a high quality yet economical geomembrane.  Nominal 20 mil, 30 mil & 40 mil available.

RUFCO PP30 and PP40 are exceptionally flexible geomembranes achieved by incorporating high levels of ethylene propylene rubber into polypropylene. Rufco polypropylene membranes contain no plasticizers that can leach out and hinder long-term flexibility and performance. RUFCO PP Series provides outstanding resistance to environmental stress cracking even at elevated temperatures and in addition to aggressive chemical environments. RUFCO PP30 is a custom run product and is available with minimum order requirements.  Nominal 30 mil & 40 mil available.

RUFCO E15DBS is a multi-layer membrane consisting of a premium linear low density polyethylene featuring an enhanced grip surface.  Carbon black additive provides protection from UV rays and harsh weather conditions. Puncture and tear strengths far exceed common polyethylene or vinyl films.  A lightly textured surface provides enhanced grip for ease of installation and worker safety.  RUFCO E15DBS provides the answer to applications requiring a low-cost sheeting with high puncture and tear strengths in a light-weight film.  Nominal 15 mil available.

RUFCO E30BS is a multi-layer, coextruded, linear low density polyethylene geomembrane with an anti-skid surface on both sides.  Fine N110 carbon black and high performance stabilizers provide long-term protection from thermal oxidation and ultraviolet degradation.  A combination of premium linear polyethylene’s providing exceptional toughness, multi-axial elongation and impact resistance.  RUFCO E30BS is used in lining and cover applications requiring good outdoor weatherability, toughness and puncture resistance.   A lightly textured surface provides enhanced grip for ease of installation and worker safety without the VELCRO® type adhesion that can make deployment over non-wovens difficult.  The products ability to conform to uneven surfaces and resist puncture through multi-axial elongation allows it to be used in a wide variety of applications.  Nominal 30 mil available.

VAPORBLOCK® PLUS™ Moisture/Gas Barrier Membrane)

VAPORBLOCK PLUS VBP20 s a seven-layer co-extruded barrier made from state-of-the-art polyethylene and barrier resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VAPORBLOCK PLUS VBP20 is a highly resilient underslab / vertical wall barrier designed to restrict naturally occurring gases such as radon and/or methane from migrating through the ground and concrete slab. VAPORBLOCK PLUS VBP20 is more than 50 times less permeable than typical high performance polyethylene vapor retarders against Methane, Radon and other harmful VOCs. Nominal 20 mil available.
