Brownfield & Gas Barriers
Many Brownfield sites are contaminated from activities undertaken at the site previously. In January of 2002, the Brownfields Revitalization and Environmental Restoration Act of 2001, in conjunction with small business liability protection; was signed into law to promote and encourage the cleanup and revitalization of Brownfields. Raven provides innovative solutions with engineered barrier geomembranes to prevent dangerous gases and VOC's from migrating to the surface and into the environment.
The Raven Absolute Barrier™ line is made from state-of-the-art polyethylene and premium EVOH barrier resins providing unmatched impact strength as well as superior resistance to gas transmission and VOCs. Absolute Barrier membranes are highly resilient and are designed to restrict naturally occurring gases such as methane, radon, and dangerous VOCs such as gasoline, benzene, toluene, ethylbenzene, o-xylene and many others from migrating through the ground and concrete slab.
Additionally, our knowledgeable geo staff can help design a custom barrier membrane for projects requiring specific criteria when meeting minimum order amount requirements.
High Performance Absolute Barriers™ EVOH Series:
- Superior impact and puncture strength
- Outstanding barrier characteristics
- Blocks odors, methane, & VOCs
- Excellent tear resistance
- Flexible and conforming
Raven VaporBlock Plus is an under-concrete-slab gas barrier system with superior resistance to gas offering 200 times more protection against methane and other VOC’s than premium polyethylene barriers. VaporBlock Plus meets all requirements of ASTM E-1745, Class A, B & C and is produced under the strict guidelines of our ISO 9001 certified management system. VaporBlock Plus is available in a 20 mil (10’ x 150’) roll along with the select accessory items recommended. Accessory items include (VaporSeal Tape) seaming tape, (Butyl Seal Tape) double sided perimeter tape, and (VaporBoot Plus Kit) pipe boot kits, as well as our multi-pipe penetration epoxy (POUR-N-SEAL) to provide a complete and thorough system of protection against gas and moisture migration.
