Crawl Space Depressurization (CSD) System

IAT designs and commissions crawl space depressurization (CSD) systems. These systems reduce and eliminate entry into the living space of crawl space fungal emissions of gases and spores, of soil gas (e.g. radon), and of humidity. This is done by covering exposed soil with vapor barrier sheeting, sealing ductwork, sealing perimeter cracks, installing radiant heating, and exhausting and depressurising the crawl space with a low energy continuous duty blower. CSD systems can be installed in conjunction with other ECHO System construction or as a stand-alone measure.

A CSD System can be installed and operating within two days, and reductions in fungal odors and allergenic effects achieved within a few hours of operation.
