Advanced Structural Drying (ASD) is the effective, efficient drying of water-damaged buildings and dwellings, using comprehensive knowledge and tools. The process includes the collection of appropriate data for utilization and application of scientific and technical principles. Psychrometry - the science of drying, helps to track moisture content, drying progress, and the verification of project completion. In many cases, ASD uses more equipment to accelerate drying, thus reducing costs, time, and the inconvenience related to replacement and repairs.

Specialized training in ASD helps in understanding the science of water damage and best practices on water losses. Psychrometric science includes atmospheric air mixtures, their evaluation, control and effect on material, and the comfort level of occupants. With a reasonable understanding of psychometrics, restorers can often dry and restore materials, which in the past were demolished and rebuilt. Science and best practices to dry building materials using airflow, amplified dehumidification, and controlling temperature/energy provide exceptional results to dry structures.
