ill�lp Designation: E1643 -11 �1 tAfTERNdTlONON3L Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs' This standard is issued under the fixed designation E1643; the number immediately following the designation indicates the year of original adoption or, in the case of revision. the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (s) indicates an editorial change since the last revision or reapproval. 1. Scope This practice covers procedures for selecting, designing, installing, and inspecting flexible, prefabricated sheet mem- branes in contact with earth or granular fill used as vapor retarders under concrete slabs. 1.2 Conditions subject to frost and either heave or hydro- static pressure, or both, are beyond the scope of this practice. Vapor retarders are not intended to provide a waterproofing function. 1.3 The values stated in inch -pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to Sl units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. 2.

ACI 302.2R-06 Guide for Concrete Slabs that Receive Moisture -Sensitive Flooring Materials 3. Significance and Use 3.1 Vapor retarders provide a method of limiting water vapor transmission and capillary transport of water upward through concrete slabs on grade, which can adversely affect floor finishes and interior humidity levels. 3.2 Adverse impacts include adhesion loss, warping, peeling, and unacceptable appearance of resilient flooring; deterioration of adhesives, ripping or separation of seams, and air bubbles or efflorescence beneath seamed, continuous floor- ing; damage to flat electrical cable systems, buckling of carpet and carpet tiles, offensive odors, growth of fungi, and unde- sired increases to interior humidity levels. 4. Manufacturer's Recommendations 4.1 Where inconsistencies occur between this practice and the manufacturer's instructions, conform to the manufacturer's instructions for installation of vapor retarder. 5. Material, Design, and Construction 5.1 See ACI 302.2R-06 for material, design, and construc- tion recommendations. 5.2 See Specifications E1745 and E1993 for vapor retarder specifications. 5.3 Vapor Retarder Material Selection—The following cri- teria should be considered when selecting a vapor retarder material. 5.3.1 Local building code and regulatory requirements. 5.3.1.1 Comply with local building code and regulatory requirements as a minimum consideration. 5.3.2 The water -vapor permeance of the vapor retarder material. 5.3.2.1 The water vapor permeance of the vapor retarder material shall be at such a rate so that adverse impacts to floor finishes and coatings do not occur ' Available from American Concrete Institute (ACI), P.O.
