Concrete Vapor Barriers What are They? The Concrete

A much better approach is a true vapor barrier, with characteristics that conform to the requirements of ASTM E-1745, "Standard Specification for Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs." This specification has three classes of vapor retarders (or barriers--the terms are still often used interchangeably), Class A, B, and C.

Uncontrolled water vapor through concrete slabs has cost building owners, designers and contractors billions of dollars. The use of underslab vapor barriers is the best method and most economical solution for controlling water vapor migration through concrete slabs. Vapor and Gas Barriers

Vapor Barriers Under Concrete Floor Slabs: Friend or Foe?

Before one can make the best decision regarding whether or not to place a vapor barrier under a concrete floor slab-on-grade, it is important to understand the sources of moisture, how it moves through the slab, and how it adversely affects certain floor coverings, adhesives, and coatings.

Concrete Vapor Barriers The Concrete Network

The last thing you want your customers to envision when thinking of a concrete floor is a damp, cold basement slab. One of the reasons those old basement floors were like that was because they had no vapor barrier beneath them, leaving an easy path for water vapor from the soil to migrate into the slab, assuring that the cold clammy damp feeling never went away.

10 Critical Reasons Why You Need a Below-Slab Vapor

A high-performance vapor barrier, once again, can eliminate one of the variables which leads to the condition in the first place. By reducing the moisture gradient and diffusion in your slab, you can virtually eliminate efflorescence caused by under-slab water vapor migration.

CIP 29 Vapor Retarders Under Slabs on Grade

CIP 29 Vapor Retarders Under Slabs on Grade WHAT are Vapor Retarders? Vapor retarders are materials that will minimize the trans-mission of water vapor from the sub-slab support sys-tem into a concrete slab. Vapor retarders are typically specified according to ASTM E 1745 and have a per-meance of less than 0.3 US perms (0.2 metric perms),

Concrete Slab Vapor Barrier or Vapor Retarder?

Accordingly, standard practice for concrete slabs in most situations is to install a vapor barrier or vapor retarder to inhibit the amount of moisture that can contact the underside of the slab. However, the choice between vapor barrier or vapor retarder can become a gamble of upfront costs vs. long-term risk.
