Vapor barriers under concrete slabs Stego Industries

2017-10-6  Vapor barriers under concrete slabs Should the concrete be placed directly on the vapor barrier? By Bruce A. Suprenant Figure 1. A vapor barrier is effective in preventing water inflow from the ground-water through the concrete slab. Using a vapor barrier in combination with a gran-ular capillary break provides the greatest resistance to water

Vapor Barriers under Concrete Floor Slabs: Friend or Foe?

Vapor barriers have been associated with certain concrete slab-on-grade problems including curling and cracking. But they have also proven to be beneficial in reducing failures of moisture-sensitive flooring materials, adhesives, and coatings caused by excessive emission of moisture vapor from concrete slabs.

Vapor barrier under exterior slab-on-grade?? Concrete

2002-4-8  For slabs without covering, a vapor barrier directly below the slab increases the potential for curling and diminishes the slab-life. In addition, if your project is a tilt-up concrete system, the slab will usually be placed first, before the roof structure, exposing the slab to exterior rain.
