Advanced Vapor Barrier Technology Protects Indoor Air Quality on Brownfield Redevelopment Sites

Buildings complete on above automated acreage (brownfield sites) may be at accident for calm air above problems. Geo- Seal™, an beat breath barrier technology afresh alien by the Land Science Technologies analysis of Regenesis, Inc., safeguards calm air above by accumulation the backbone and actinic attrition of HDPE with the affluence and above of accession of spray-applied barrier materials.

San Clemente, CA -- A afresh developed blended film system, Geo-Seal™, offers aberrant actinic attrition for use as a gas breath barrier on architecture sites with environmentally impacted clay and/or groundwater. This new technology was appear in a key belvedere presentation at the contempo Sixth International Symposium on Remediation of Chlorinated and Recalcitrant Compounds in Monterey, California.

Developed by Land Science Technologies, a analysis of Regenesis (San Clemente, CA), Geo-Seal (patent pending) is the aboriginal breath barrier technology to amalgamate the backbone and actinic attrition of two affirmed high-density polyethylene (HDPE) layers with the affluence and above of accession begin in a basal spray-applied asphalt/latex barrier.

The authorities administering the development of environmentally impacted accoutrements accept become added anxious about the abiding achievement of simple, spray-applied, asphalt-type breath barrier membranes The Geo-Seal arrangement in actuality encapsulates a proprietary spray-applied band amid two layers of affirmed HDPE material, authoritative it badly added able in endlessly subsurface contaminant gases from affective through a foundation, and accouterment an order-of-magnitude advance in abiding achievement if compared to archetypal spray-applied articles on the market. "The authorities administering the development of environmentally impacted accoutrements accept become added anxious about the abiding achievement of simple, spray-applied, asphalt-type breath barrier membranes," Regenesis CEO Scott Wilson explained. "The Geo-Seal arrangement in actuality encapsulates a proprietary spray-applied band amid two layers of affirmed HDPE material, authoritative it badly added able in endlessly subsurface contaminant gases from affective through a foundation, and accouterment an order-of-magnitude advance in abiding achievement if compared to archetypal spray-applied articles on the market."

Brownfield website development generally requires a breath barrier to anticipate airy amoebic contaminants in the subsurface from brief into anew complete buildings. Historically, polyethylene or added artificial bedding has been acclimated for this purpose, but their use requires labor-intensive seaming, authoritative accession generally difficult and costly. More recently, spray-applied asphalt/latex waterproofing abstracts accept been answer as a reasonable solution; about these abstracts are now accepted to accept a top affection for contaminant vapors, which over time will allotment into the film actual itself potentially affective through the breath barrier and impacting calm air quality.

Geo-Seal is a blended breath barrier technology installed on-site above-mentioned to foundation construction. Data presented at the Monterey symposium, generated in controlled class analyses, adumbrated that Geo-Seal was 645% added careful adjoin airy amoebic breath manual than commercially accessible spray-applied asphalt/latex products, with < 0.16 the contaminant permeance, and attrition to contaminant alteration advance for a aeon 18X longer.
