Significance and Use | ||||||||
Vapor retarders provide a method of limiting water vapor transmission upward through concrete slabs on grade, which can adversely affect moisture-impermeable or moisture-sensitive floor finishes. Adverse impacts include adhesion loss, warping, peeling, and unacceptable appearance of resilient flooring; deterioration of adhesives, ripping or separation of seams, air bubbles or efflorescence beneath seamed, continuous flooring; damage to flat electrical cable systems, buckling of carpet and carpet tiles, offensive odors, and growth of fungi. |
