EMS: Environmental Management Solutions

Vapor Barriers

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's 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, waterbased 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 fullyadhered 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.
