How thick is a vapor retarder?
High-performance vapor retarders and barriers are commonly available in 8-mil, 10-mil, 15-mil and 20-mil thicknesses. As mentioned, increased thickness does not always translate into better performance. Avoid single extruded products made from recycled content. For example, a 10-mil single layer extruded film made from recycled content will not carry near the performance of a thinner 8-mil co-extruded film manufactured from virgin resin. When evaluating vapor retarder and barrier products, it is key to make sure they are made from virgin resin and are co-extruded films.
What is the best way to protect concrete slabs?
As a best practice, select products meeting the ASTM E 1745 Class A requirements.

Why is moisture in concrete flooring?
Other causes for moisture related flooring and IAQ issues relate to concrete slab placement and drying time. Historically slabs were placed directly over a layer of sand with the idea to protect the polyethylene sheeting from damage during concrete placement and provide a means for bleed water to exit freshly placed concrete. The problem with this method is that while the sand layer does absorb excess water, the water gets trapped once it reaches the layer of polyethylene sheeting. Similar to water vapor diffusion from the soil, once the building is enclosed and RH below the slab seeks equilibrium, the trapped bleed water has nowhere to go but up. Oftentimes the flooring system is prematurely allowed to be placed as the water within the sand layer goes undetected.
