LIQUID BOOT® — Gas Vapor Barrier System
System Description
Liquid Boot® is a seamless, spray-applied, water-based membrane containing no VOCs, which provides a barrier against vapor intrusion into structures
Liquid Boot® is installed under slab and on below grade vertical walls as a gas vapor barrier to minimize vapor and nuisance water migration into buildings and is ideal for methane migration control.
Liquid Boot® spray-application directly to penetrations, footings, grade beams, pile caps, etc., provides for a fully-adhered gas vapor barrier system.
Typical Uses
Underslab and below-grade vertical wall gas vapor barrier, used to minimize vapor and
nuisance water (non-hydrostatic conditions) migration into buildings.
Ideal for methane migration control.
Concrete water reservoir and tank liner used to prevent water seepage into concrete.

Benefits
Spray application provides excellent sealing of penetrations, eliminating mechanical fastening.
Seamless, monolithic membrane eliminates seaming-related membrane failures.
Unique formulation provides superior protection from methane gases and water vapor.
Fully adhered system reduces risk of gas migration.

LIQUID BOOT® — PLUS Gas Vapor Barrier System
System Description
The Liquid Boot® PLUS system is a combination of the traditional Liquid Boot® spray-applied membrane and VI-20™, a 20-mil, high performance polyethylene-EVOH copolymer membrane.
The system, paired with the GeoVent™ Gas Venting System, is designed to provide excellent resistance to contaminants.
The Liquid Boot® membrane is spray-applied to a uniform substrate, provided by the VI-20™ geomembrane, bonding together to create a highly resistant protection barrier.
Once the membrane is fully cured, UltraShield™ non-woven geotexile protection course is installed.
Typical Uses
Installed under slab and on below grade vertical walls as a gas vapor barrier to minimize
vapor and nuisance water (non-hydrostatic conditions) migration into buildings.
Ideal for applications with chlorinated solvents, BTEX and other PAHs.

Benefits
Combines the advantages of a spray-applied membrane with the performance of a technically advanced geomembrane.
60 mil Liquid Boot® plus 20 mil VI-20™ provides excellent resistance to punctures and tears.
VI-20™ EVOH barrier technology provides superior protection against diffusion of chemicals
when compared to typical HDPE geomembranes.

GeoVent™ — Gas Venting System
System Description
GeoVent™ is a low profile pressure relief, trenchless collection and venting system designed to improve venting efficiency and reduce installation costs. GeoVent™ has several advantages over trenched installations and can be used as an “active” or “passive” venting system depending on the specific project.
Used in conjunction with Liquid Boot® or CoreFlex™ gas vapor barrier systems, GeoVent™ can alleviate the accumulation of gas vapors under the slab.
