2. Epoxy moisture control system - Wikipedia

   en.wikipedia.org/wiki/Epoxy_moisture_control_system

   Epoxy moisture control systems are chemical barriers that are used to prevent moisture damage to flooring. Excessive moisture vapor emissions in concrete slabs can mean significant, expensive damage to a flooring installation. Hundreds of millions of dollars are spent annually just in the United States to correct moisture-related problems in ...

3. Vapor barrier - Wikipedia

   en.wikipedia.org/wiki/Vapor_barrier

   A vapor barrier (or vapour barrier) is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings and of packaging to prevent interstitial condensation.

4. Damp proofing - Wikipedia

   en.wikipedia.org/wiki/Damp_proofing

   Concrete normally allows moisture to pass through so a vertical vapor barrier is needed. Barriers may be a coating or membrane applied to the exterior of the concrete. The coating may be asphalt, asphalt emulsion, a thinned asphalt called cutback asphalt, or an elastomer. [9] Membranes are rubberized asphalt or EPDM rubber. Rubberized products ...

5. Waterproofing - Wikipedia

   en.wikipedia.org/wiki/Waterproofing

   Walls also have vapor barriers or air barriers. Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp , and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where ...

6. Interstitial condensation - Wikipedia

   en.wikipedia.org/wiki/Interstitial_condensation

   Vapor barriers can be problematic because they difficult to install perfectly and also reduce the ability of a cavity to dry out when it does get wet. Vapor barriers are used in conjunction with a housewrap which are vapor permeable but a water resistant membrane, so that one side of the cavity is permeable to allow drying. [ 5 ]

7. Moisture vapor transmission rate - Wikipedia

   en.wikipedia.org/wiki/Moisture_vapor...

   Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.
