Hydrostatic Pressure and Capillary Moisture Movement (Concrete / Substrates)
Floor Detective® Claims and Conditions Guide
Summary
Hydrostatic pressure and capillary moisture movement describe moisture conditions within or beneath a concrete slab that affect flooring-system performance. True hydrostatic pressure involves standing water exerting upward force against the slab, while most flooring-related moisture issues result from capillary migration and vapor pressure differentials. Moisture movement through the slab may transport soluble salts, influence alkalinity, and affect adhesive performance and bond integrity. These conditions reflect substrate moisture dynamics and environmental interaction rather than a defect in the flooring material itself.
