Stego
Below-slab vapor barriers used to reduce moisture movement from the ground into the home.
Concrete is porous. Without proper protection, moisture from the ground can move through the slab and affect flooring, materials, and indoor air quality.
Stego creates a continuous vapor barrier beneath the slab, adding margin where standard minimums can leave little room for jobsite damage or long-term exposure.
It is a hidden detail, but it protects everything built above it.
