About This Item
ASTM E1745 is the ASTM standard for plastic water vapor retarders used in contact with soil or granular fill under concrete slabs. It provides a technical basis for evaluating materials intended to help limit moisture transmission from the ground into slab-on-grade construction. This matters because vapor retarder performance can affect floor covering compatibility, slab durability, and overall moisture control in concrete systems where ground contact is expected.
Purpose of ASTM E1745
The purpose of this standard is to define requirements for plastic water vapor retarder materials used beneath concrete slabs where they contact soil or granular fill. ASTM E1745 supports consistent material specification by giving purchasers, designers, and suppliers a common reference for product evaluation. In practice, it helps align expectations for material performance and suitability in slab construction, especially where moisture protection is an important design consideration.
Common use cases of ASTM E1745
This standard is commonly used when specifying vapor retarder materials for concrete slabs placed over soil or granular fill. It is relevant to slab-on-grade construction, where the installed membrane or sheet material is intended to reduce moisture movement from beneath the slab. ASTM E1745 is often referenced by project specifications, procurement teams, and quality control personnel selecting a compliant retarder for concrete placement.
Why ASTM E1745 matters
ASTM E1745 matters because it helps create consistency in product selection and compliance for under-slab moisture control materials. A clear standard makes it easier to compare products, support procurement decisions, and reduce the risk of performance issues tied to moisture migration. For contractors, specifiers, and inspectors, ASTM E1745 provides a practical benchmark for evaluating whether a plastic water vapor retarder is appropriate for the intended concrete slab application.
