Liquid Boot - Model Plus -Spray-Applied Vapor Barrier
For high-risk underslab and below-grade vertical walls, LIQUID BOOT® PLUS combines traditional Liquid Boot® spray-applied membrane with high-performance VI-20™, a 20-mil polyethylene-EVOH copolymer membrane, to form a superior vapor intrusion barrier that’s ideal for VOCs including BTEX and chlorinated solvents. Even greater contaminant resistance is achieved when LIQUID BOOT PLUS is installed with our GEOVENT gas venting system along with a course of our ULTRASHIELD non-woven geotextile protection to create a superior, highly-resistant protection barrier.
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.
