Seamless brownfield membrane liner & vent system

In the face of society’s increasing needs and limited space, the rehabilitation of brownfields remains a necessary, complex and dynamic challenge. CETCO. Inc, the manufacturers of LIQUID BOOT®, has offered an innovative and reliable solution to meet the challenge of gas vapor containment. With more than 25 years of proven performance, LIQUID BOOT® is the answer to providing an impermeable membrane for brownfield sites. With millions of square feet already in place, LIQUID BOOT® sets the industry standard to prevent potentially hazardous gases or vapors from entering a structure. The combination of the unsurpassed quality of LIQUID BOOT® along with the technical expertise of our in-house engineers has lead CETCO, Inc., to the forefront of membrane brownfield redevelopment. We are ready to work with you in helping to revitalize, enhance and protect some of the best situated properties in your city.
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.
- Underslab and below-grade vertical wall gas vapor barrier (non-hydrostatic conditions)
- Ideal for methane and radon migration control
- Concrete water reservoir and tank liner used to prevent water seepage into concretes
