2016年10月25日 · ASTM E1643, by citing important material and construction considerations, assists the architect in identifying best practices for designing under-slab vapor proofing systems. In addition, Appendix X provides non-mandatory pre-design considerations to be used along with the selection criteria for design professionals described above.

Current edition approved March 1, 2017. Published March 2017. Originally approved in 1994. Last previous edition approved in 2011 as E1643-11. DOI: 10.1520/E1643-11R17.

2024年6月12日 · 1.1 This practice covers procedures for selecting, designing, installing, and inspecting flexible, prefabricated sheet membranes in contact with earth or granular fill used as vapor retarders under concrete slabs. 1.2 Conditions subject to frost and either heave or hydrostatic pressure, or both, are beyond the scope of this practice.

2022年10月26日 · When it comes to vapor barrier installation, the ASTM has set a standard: ASTM E1643, Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs. We have outlined the four sections found within ASTM E1643 for vapor barrier installation:

1.1 This practice covers procedures for selecting, designing, installing, and inspecting flexible, prefabricated sheet membranes in contact with earth or granular fill used as vapor retarders under concrete slabs. 1.2 Conditions subject to frost and either heave or hydrostatic pressure, or both, are beyond the scope of this practice.

PERMINATOR is a 10 and 15 mil underslab vapor barrier & vapor retarder designed to prevent moisture, radon, and methane gas intrusion. With superior puncture resistance and low perm ratings, it protects concrete slabs, radiant heating systems, and …

It outlines procedures to limit water vapor transmission and protect floor finishes. The standard references other documents and provides criteria for choosing appropriate vapor retarder materials based on factors like permeability, strength, and site conditions.

2018年2月15日 · Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs.

ASTM E 1643, "Standard Practice for Installation of Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs," provides details, but here are a few tips: Most exterior slabs do not need a vapor barrier. If you are going to seal an exterior slab, find a sealer that transmits water vapor (breathes).

ASTM E1643 is an installation standard titled, "Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs."
