Structural dry-out is not simply about blowing hot air onto a wet floor. Vetted restoration professionals utilize advanced psychrometry—the study of the thermodynamic properties of moist air—to extract trapped humidity scientifically.
1. Vapor Pressure and Evaporation Rates
Water naturally migrates from areas of high vapor pressure to areas of low vapor pressure. By deploying commercial-grade LGR dehumidifiers, technicians lower the ambient relative humidity, reducing the vapor pressure of the air. This creates a steep pressure differential that forces moisture trapped deep within structural timbers and subfloors to evaporate rapidly.
2. Calculating Specific Humidity
Specific humidity, measured in grains of moisture per pound of dry air (GPP), is the absolute measure of water vapor present in an indoor space. Dispatched technicians monitor GPP daily, calculating the exact dew point to ensure that condensation does not occur on cold surfaces. This stops the spread of structural swelling and latent decay.
3. Balancing CFM and Airflow
High-velocity air movers are placed strategically to deliver constant cubic feet per minute (CFM) across wet materials. This constant airflow breaks the stagnant boundary layer of saturated air directly above the floor, allowing the dehumidifiers to capture the evaporated water continuously.
