Structural drying is the scientific process of extracting bound moisture from deep inside porous and semi-porous building materials—including wooden framing studs, subfloors, drywall, concrete slabs, and masonry. Even when a room feels dry to the touch, structural framing can harbor dangerous moisture levels that cause wood rot, warping, and hidden mold colonies.
Certified restoration technicians apply psychrometrics—the science of drying air. By strategically positioning high-velocity axial air movers, technicians sweep high-speed laminar airflow across wet surfaces, lifting bound water molecules into the air via evaporation.
Simultaneously, commercial Low-Grain Refrigerant (LGR) dehumidifiers capture that humid air, condense the moisture into liquid, and pump it out of the structure. Technicians log relative humidity, ambient temperature, and specific humidity in grains per pound (GPP) daily until materials reach equilibrium moisture content.
