LIQUID BOOT® Vapor Intrusion Barrier Systems

High performance gas vapor mitigation system 

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.

Vapor-Intrusion-Barrier_sm
    Overview

    The LIQUID BOOT systems are ideal for methane and VOC vapor control. They can be spray applied to penetrations, footings, grade beams, pile caps and other irregular surfaces, providing a seamless and fully adhered vapor intrusion barrier system. LIQUID BOOT multi-layer systems can be tailored to meet the chemical resistance needs of your project.

    BASEFABRIC™
    BASEFABRIC™ fabric consists of polypropylene, non-woven geotextile that is resistant to ultraviolet degradation and to biological and chemical environments normally found in soils. BaseFabric provides a uniform substrate for spraying the Liquid Boot membrane.

    GeoVent_(45)

    GEOVENT™
    GEOVENT™ consists of a three-dimensional vent core that is wrapped in a non-woven, needlepunched filter fabric.

    Trowel_Grade

    LIQUID BOOT® TROWEL GRADE
    LIQUID BOOT® TROWEL GRADE is a trowel-applied, water-based membrane containing no VoCs, which provides a barrier against vapor intrusion into structures. LIQUID BOOT TROWEL GRADE is installed in conjunction with the LIQUID BOOT vapor intrusion barrier to minimize vapor migration.

    VI-20™ GEOMEMBRANE
    VI-20™ is a 7-layer co-extruded EVOH geomembrane made using high quality virgin-grade polyethylene and barrier resins that provide unmatched impact trength as well as superior resistance to VOC vapor transmission. EVOH technology serves as a highly resilient underslab and vertical wall barrier designed to restrict methane, radon and other harmful chemicals. Applications for EVOH originatedin them of hydrocarbons, whose use was mandated by the US EPA and the CA Air Resources Board (CARB) to reduce VOC emissions.
