Gas and Vapor Barrier Installation
EMS supplies and installs various types of gas/vapor barrier systems as well as design assistance during project planning. As an engineering control for pollution containment, an impermeable membrane is ideal for use on brownfield and other contaminated sites. EMS can offer a tailored solution based on site specifics, including liquid boot.
EMS is a certified applicator and distributor of the CETCO liquid boot products and gas vent system. Liquid boot is a cold spray-applied water-based membrane that contains no volatile compounds and provides a seamless barrier against vapor intrusions into structures.
Liquid boot is a cold, spray-applied, water-based membrane containing no VOCs, which provides a seamless, impermeable barrier against vapor intrusion into structures. Liquid boot is spray-applied directly to penetrations, footings, grade beams, pile caps, etc., providing a fully-adhered gas vapor barrier system.
The low-profile pressure relief, trenchless collection and venting system (PRCVS) has several advantages over a trenched installation and can be used as an “active” or “passive” venting system depending on the specific project. Combined with liquid boot gas vapor membrane, the PRCVS system alleviates the accumulation of vapors under the slab.
Liquid boot gas vapor barrier and the gas venting system are the most widely known and used vapor intrusion mitigation system used today. More than 50 million square feet of liquid boot has been installed under hospitals, schools, libraries, high-rise commercial and residential buildings, single-family housing developments and major public works projects. Liquid boot is the global leader in cold-spray applied gas vapor membrane and venting technology. No other membrane technology has been tested as extensively as liquid boot.
Liquid boot is the industry standard in gas vapor membrane technology and is designed to eliminate vapor intrusion into structures built on brownfields or any other contaminated sites, i.e. former landfills and manufacturing facilities, former dry cleaners and gas station sites, etc. Liquid boot has superior chemical resistance properties and seals all vapor intrusion pathways, preventing contaminated soil vapors from penetrating the slab.
