LIQUID BOOT® Vapor Intrusion Barrier Systems

High performance Vapor Intrusion Barrier Systems designed to meet your project requirements

LIQUID BOOT is a spray-applied, water-based membrane containing no volatile organic compounds (VOCs). With superior chemical resistance properties it seals all vapor intrusion pathways, preventing contaminated soil vapors from penetrating the slab. LIQUID BOOT spray applied vapor intrusion barrier systems can be used in underslab and below grade vertical wall applications to minimize gas and vapor intrusion into buildings.

    ULTRADRAIN™
    ULTRADRAIN™ consists of an impermeable polymeric sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is then bonded to a layer of non-woven filter fabric. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Ultradrain also has a protection sheet bonded to the backside of the cuspated core providing protection for soft membrane barrier systems.

    TORONTO FIRE SERVICES
    Toronto, Ontario, Canada
    Vapor intrusion has become a significant environmental issue for regulators, industry leaders, and concerned residents nationwide. The use of a spray-applied gas vapor barrier to protect against the threat of vapor intrusion has become a widely recognized application by numerous local and state regulatory and guidance groups. These groups also recommend that a gas venting system be used in conjunction with the gas vapor barrier for optimum mitigation of gas vapor.
