Liquid Boot - Spray-Applied Gas Vapor Barrier
From Environmental Products - Liquid Boot
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. LIQUID BOOT spray-application directly to penetrations, footings, grade beams, pile caps and other irregular surfaces, provides for a fully-adhered gas vapor barrier system.
Product Details
LIQUID BOOT - For moderate-risk underslab and below-grade vertical walls, LIQUID BOOT® is an effective vapor intrusion barrier for methane, CO2, and low-level VOCs such as BTEX and chlorinated solvents. It can also be used as a concrete water reservoir and tank liner to prevent water seepage into concrete.
Applications
LIQUID BOOT® is used as an underslab and below-grade vertical wall gas vapor barrier, used to minimize vapor and nuisance water (non-hydrostatic conditions) migration into buildings. LIQUID BOOT® is ideal for methane migration control. LIQUID BOOT® is also NSF® certified for use as a potable water liner in concrete water reservoirs and tanks greater than 300,000 gallons to protect the concrete from water seepage.
Benefits
- Spray-application provides excellent sealing of penetrations, eliminating the need for 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
- Protection from methane gas, VOCs, chlorinated\ solvents and other contaminates
How it does it
LIQUID BOOT is a seamless, spray-applied rubberized asphalt formed from a waterborne emulsion and catalyst that are sprayed simultaneously from a dual-nozzle wand and combined with a geomembrane to create an effective protective barrier against vapor intrusion into a structure.
LIQUID BOOT PLUS combines the advantages of LIQUID BOOT with VI-20™, a seven-layer co-extruded EVOH geomembrane made using high quality virgin-grade polyethylene and barrier resins for impact strength and VOC vapor transmission resistance. EVOH is a copolymer of polyethylene, polyvinyl alcohol, and ethylene vinyl alcohol that demonstrates OC diffusion coefficients 20 times lower than 80 mil HDPE geomembrane to restrict methane, radon, and other harmful chemicals.
CETCO Quality Assurance
Our experienced technical managers can assist with the technical considerations and design of a vapor intrusion mitigation system, and recommend the best solution based on various site conditions. Our systems have proven performance with an extensive record of success.
With regulations, requirements, and guidance on the use of vapor intrusion barrier systems varying by location, CETCO can help you establish maximum risk criteria for indoor air quality and determine the appropriate vapor intrusion barrier system solution. CETCO maintains a nationwide network of certified installers and inspectors who are trained in proper installation and inspection procedures to ensure a successful installation. CETCO pioneered the use of the smoke test, where smoke is pumped under the membrane for a period of time and the membrane surface is observed for smoke to detect and immediately repair minute holes where the smoke is visible. Smoke testing is currently recognized by top guidance organizations as a reliable quality control method for vapor intrusion barrier systems.
