ABSOLUTE BARRIER™ E-Series EB25BS High Performance Geomembrane Gas Barrier & Enhanced Grip Surface Product Description Absolute Barrier™ EB25BS is a seven layer co-extruded geomembrane consisting of a very flexible, linear low-density polyethylene (LLDPE) and an inner core of chemically resistant EVOH, designed specifically as a barrier. High strength LLDPE provides exceptional tear and impact resistance. A robust stabilization package that exceeds the industry standard provides long-term protection from thermal oxidation and ultraviolet degradation in exposed applications. A lightly textured surface provides enhanced grip for ease of installation and worker safety. Product Use Absolute Barrier™ EB25BS is designed to stop gas vapor migration on Brownfield sites, in residential and commercial buildings as well as geomembrane containment and covering systems. When installed under concrete slabs as a gas barrier, a passive system is recommended to include a ventilated system with sump(s) that could be converted to an active control system with properly designed ventilation fans. Absolute Barrier™ EB25BS provides superior protection against deadly radon gas when installed as an under-slab gas barrier with a radon diffusion coefficient of 7.0 x10−14m2/s. EB25BS is over 800 times less permeable to methane gas than LLDPE vapor barriers in a comparable thickness. Absolute Barrier™ EB25BS is an effective temporary and long term landfill cap with VOC diffusion coefficients ranging from 20 to 38 times less than standard 80 mil HDPE geomembranes. Contaminants found in leachate and landfill gas in municipal and hazardous waste landfills can migrate through standard HDPE contributing to both atmospheric and groundwater contaminations. EB25BS is an effective barrier to a wide range of VOCs including benzene, toluene, ethylbenzene, o-xylene and others.
