Vapor barriers are used because while fresh concrete is poured wet it s not supposed to stay that way.

Moisture barrier on concrete slab.

A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. If you want to make sure your slab on ground gets dry and stays dry use a vapor barrier. Meadows 10 and 15 mil vapor barrier. Meadows makes a concrete vapor barrier called perminator.

Cure with waterproof sheets rather than with water or curing compounds. To take it one step further astm e 1745 class a vapor barriers products with less than 0 01 perms are the best approach to protecting your concrete slab and components moisture sensitive floor and iaq from moisture sources below. Perminator also helps reduce radon gases from entering a building through. All vapor barriers should conform to astm e 1745.

Perminator vapor barriers help reduce the penetration of moisture and water vapor through the slab and into the building which helps reduce mold fungus and mildew. A concrete vapor barrier is simply a sheet of polyethylene plastic visqueen placed directly on top of the sub grade before the concrete floor or slab is poured to help keep moisture from the soil from passing up through the concrete. Once the slab is poured the excess moisture must leave the slab in order to strengthen the concrete bond. These principles mean that if the relative humidity in the concrete slab is different than the relative humidity of the air above the slab then moisture is going to try to move in or out of the slab.

Without a vapor barrier the relative humidity in the slab just below the surface can often be 100. Vapor barriers have been associated with certain concrete slab on grade problems including curling and cracking. However allowing excess moisture to leave the slab after it s poured is crucial to a successful flooring installation. It needs to dry and then stay dry to avoid flooring problems.

But consider going with a barrier that has water vapor permeance less than 0 3 perms. Choosing a vapor barrier. These plates must be made of pressure. Sole plates or sill plates are the first pieces of framing lumber placed in home construction.
