Concrete can be “wet” by test yet dry where it matters.

Barrier One Concrete Admixtures Porosity Inhibiting Admixture (PIA) addresses moisture at the source by controlling internal moisture movement, not just surface conditions.   By sealing capillaries within the concrete slab, PIA prevents moisture migration that can lead to flooring failures — even when Relative Humidity (RH) readings remain elevated.

That’s why Barrier One Concrete Admixtures One PIA is warranted to the limits of:

ASTM F2170 (In-Situ Relative Humidity)
ASTM F1869 (Moisture Vapor Emission Rate)
Proven protection from the inside out.
