6 mil is the minimum for moisture control, with 20 mils being the most sturdy and puncture-resistant. Foam can stop or slow moisture depending on the type and thickness, but when you pour a slab it is very easy for the insulation to be moved and leave gaps, concrete will fill those gaps and endlessly wick moisture into your house. The IRC identifies 6-mil polyethylene as the minimum acceptable barrier for under concrete, and the ACI states 10-mil poly as their minimum recommended choice. Vapor barrier thicknesses range from 6 mils to 20 mils. When a vapor barrier is on the side of a wall where the dry air is (i.e., outside in winter or inside in summer), moisture problems can occur. Reference American Concrete Institute (ACI) 302.1R-04: Chapter 4, Section 4.1.4 Base Material for sub-grade preparation prior to placement of PERMINATOR. They have a thin, often 6 mil, poly vapor barrier attached. You need a sub slab vapour barrier. Stego's cutting-edge 20-Mil Vapor Barrier provides additional protection for crucial projects and is frequently used on high-profile projects such as data centers and hospitals. However, the vapor barrier under the slab must have a lower degree of permeance than the flooring (or floor covering) above the slab. The ideal thickness of a moisture barrier depends on how prone the area is to dampness. Learn how to install a vapor barrier Follow ASTM E-1643-10 (standard practice and procedure for installation of vapor retarder used in contact with earth or fill under concrete slabs). There is a range of these including those made from rubber, synthetic rubber, foam and cork. 6 mil is the minimum for moisture control, with 20 mils being the most sturdy and puncture-resistant. Follow ASTM E-1643-10 (standard practice and procedure for installation of vapor retarder used in contact with earth or fill under concrete slabs).

PERMINATOR (10 and 15 Mil Underslab Vapor Barrier): PERMINATOR underslab vapor barrier is a new generation of polyolefin-based resin/chemical technology. One inch of extruded polystyrene (XPS) has a vapor permeance that ranges from 0.4 perm (that would be a vapor barrier) to 1.6 perm (a vapor retarder, not a vapor barrier), depending on the brand. There is a range of these including those made from rubber, synthetic rubber, foam and cork. A 15-mil vapor barrier can be about 25 cents per square foot. A 15-mil vapor barrier can be about 25 cents per square foot. 6 mil is the minimum for moisture control, with 20 mils being the most sturdy and puncture-resistant. Details. All Viper II products are tested and engineered to meet and exceed the Class A, B and C requirements outlined in ASTM E 1745 (Standard Specification for Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs). However, the vapor barrier under the slab must have a lower degree of permeance than the flooring (or floor covering) above the slab. Our 6-mil plastic sheeting is a general-purpose plastic film for use in a variety of construction, gardening and DIY applications. Some designs call for the use of downspouts discharging into 6-mil plastic pipes 6 inches below grade with the same positive slope to prevent excess surface water from percolating down. Most are rolls. A 15-mil vapor barrier can be about 25 cents per square foot. 6 MIL THICK, HEAVY DUTY: Extra thick 6 Mil (.006 in) Made of Durable Low-Density Polyethylene (LDPE) MULTI-PURPOSE: Perfect for Industrial, Residential, When a vapor barrier is on the side of a wall where the dry air is (i.e., outside in winter or inside in summer), moisture problems can occur.

This heavy-duty plastic is commonly used under concrete slabs as a vapor barrier, on top of freshly poured slabs as a curing blanket, and as a temporary cover for equipment and supplies. There is a range of these including those made from rubber, synthetic rubber, foam and cork. Reference American Concrete Institute (ACI) Underlayment with an attached vapor barrier is a good choice for a floating floor basement installation.
