CETCO VMS chosen for popular restaurant situated near former dry cleaner site case study


Project: Buffalo Wild Wings Restaurant
Location: Metairie, LA
Products: Liquid Boot 500 Gas Vapor Mitigation System GeoVent Gas Venting System

Background: The location of a new, two-story Buffalo Wild Wings restaurant was adjacent to a former dry cleaner site. The primary concerns were chlorinated compounds
and benzene.

Challenge: The low lying area, primarily consisting of sandy/silty ground, provided a geomechanical challenge in addition to the numerous footings/piers that were required to support the structure and eliminate settling. Multiple grade beams and the monolithic slab design were also more of a challenge than a normal slab on grade design. Sandy stratum also allowed for increased migration of other groundwater plumes on to the subject site.

Solution: CETCO's GeoVent sub slab venting system was laid out to minimize transitions through grade beams. In addition, 8,000 square feet of the Liquid Boot 500 vapor intrusion mitigation system was utilized which allowed for reliable seals around the many penetrations and exposed piers. The Liquid Boot 500 system, along with GeoVent, provides dependable, long-term protection against potential gas vapor migration from chlorinated compounds.

Result: Installation of the Liquid Boot 500 system was completed successfully and on schedule. Asmoke test quality assurance procedure and inspection to ensure a reliable seal around the numerous exposed piers and penetrations. This site contributed to the continued improvement in land value in the Jefferson Parish area.
