LIQUID BOOT® COREFLEX® GEOVENT™ WHAT IS VAPOR INTRUSION? Vapor intrusion is the migration of subsurface chemical vapors into overlying structures. Vapors may include volatile organic compounds (VOCs), semivolatile organic compounds, inorganics (i.e. mercury, hydrogen sulfide, etc.), methane or radon. Vapor intrusion has become a signifi cant environmental issue for regulators, industry leaders, and concerned residents nationwide. CETCO offers four uniquely designed vapor mitigation systems developed to meet the needs of your brownfi eld redevelopment project. These systems offer solutions for...

LIQUID BOOT® PLUS High-Performance Gas Vapor Barrier System . Combines the advantages of a spray-applied membrane with performance of a technically advanced geomembrane . Typically 80 mil thick system provides excellent resistance to punctures and tears . EVOH barrier technology provides superior protection against diffusion of chemicals when compared to typical HDPE geomembranes 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...

COREFLEX® Methane Barrier & High-Performance Waterproofi ng System CoreFlex® is a fl exible membrane liner which functions as both a methane gas barrier and a high-performance waterproofi ng membrane. CoreFlex® features a heat welded thermoplastic membrane with the industry’s heaviest reinforcement plus Active Polymer Core (APC) Technology. The CoreFlex® dual membrane system seals both gas and water breaches with reliability. CoreFlex®s thermoplastic membrane exhibits superior puncture resistance and is integrally bonded to a proprietary APC core layer - working together to ensure superior gas...

GEOVENT™ Gas Venting System . Installed directly on subgrade eliminating costly trenching . Placed in closer proximity to the gas vapor barrier allowing for more effective venting . Greater opening area per lineal foot of pipe and integral fi lter fabric allowing for higher ventilation effi ciency . Installed at a higher elevation reducing susceptibility to inundation from perched groundwater that may accumulate beneath the building foundation . Flow characteristics meet or exceed that of a typical trenched installation. The overall capacity of the system is far in excess of typical gas fl ux...

SMOKE TESTING for Gas Vapor Barrier Systems A smoke test is a method of ensuring that a membrane is free of holes. Smoke is pumped under the membrane for a specifi ed period of time while the surface of the membrane is observed for minute holes where the smoke is clearly visible. During the smoke test, any holes detected can immediately be repaired. This process has been completed under hundreds of structures and found to be highly successful. The smoke testing process assures engineers, developers, and owners alike that they are getting a fully tested, gas-tight membrane installation. CETCO,...
