The technology for slabs on grade has mostly been below slab “vapor barriers” of all kinds and thicknesses, but the challenge with them is that they always fail, either from puncture; wrong installation; gaps in the seams; even the welded together PVC systems are susceptible to puncture, cracks, vermin chewing through it, etc. You then have trapped water under the slab that cannot go anywhere but up. This increases the hydrostatic pressure that comes through the slab as vapor drive, pushing up the salts, alkalinity, efflorescence, lime, PH, etc. These caustics eat away the bondline of the sealers, mastics, and epoxy floor systems; causing failed flooring systems and sick building syndrome (SBS; that is mold spores released in the air causing nausea and headaches to the inhabitants). Our goal is to reduce the liability of moisture damage, slab on grade, to the Architect, GC, and customer; and to enhance indoor air quality; long term. Our systems can be applied within 3 days of the pour. The owner has a 15 year warranty against moisture/alkalinity damage with no upper limits on the vapor drive.
