Raven Industries geotextiles and geogrids

Product description

ABSOLUTE BARRIER Series is a seven-layer co-extruded geomembrane consisting of virgin-grade polyethylene with an inner core of chemically resistant EVOH, designed specifically as a barrier against radon, methane, and harmful VOCs (Gasoline, Benzene, etc.). A robust stabilization package exceeds industry standards and provides long-term protection from thermal oxidation and ultraviolet degradation in exposed applications. ABSOLUTE BARRIER® geomembranes are engineered for the superior containment of hazardous contaminants in gas, odor, liquid, and solid form.

Product Description:

Absolute Barrier X-Series X40BAL and X60BAL are a seven layer co-extruded geomembranes consisting of a durable high-density polyethylene (HDPE) with an inner core of highly effective barrier resin, designed specifically as a barrier against methane, radon, and VOCs. High strength HDPE provides excellent chemical resistance and durability. A robust stabilization package that exceeds the industry standard; provides long-term protection from thermal oxidation and ultraviolet degradation in exposed applications.

 

Product Use:

Absolute Barrier X-Series X40BAL and X60BAL are 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 also performs extremely well against gasoline vapor transmission as well as other VOCs in geofoam protection applications.

Absolute Barrier X-Series X40BAL and X60BAL are effective temporary and long term landfill caps and are 50 times less permeable to VOCs 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.

Both X40BAL and X60BAL provide an effective barrier to a wide range of VOCs including benzene, toluene, ethylbenzene, o-xylene and many others.
