What does exfiltration refer to in the context of structural drying?

Exfiltration in the context of structural drying specifically refers to the movement of water vapor and/or air from the inside of a structure to the outside. This process is crucial in drying a building because it helps to remove moisture from enclosed spaces where water damage has occurred. By facilitating this outward flow of moisture-laden air, exfiltration allows for more effective drying as it helps create a difference in pressure and moisture levels, promoting evaporation and, subsequently, improving the efficiency of drying methods used in remediation.

Understanding exfiltration is important in the context of structural drying because it highlights the need for proper ventilation strategies. These strategies often include the use of fans and dehumidifiers that can enhance the movement of air and moisture away from the affected areas. This process not only aids in the reduction of humidity levels indoors but also prevents potential secondary damages related to lingering moisture, such as mold growth or structural compromise.
