The document is for technical guidance, addressing the design, installation, and operation of soil depressurization; i.e., on systems that use a fan to depressurize the soil. However, it also discusses active soil pressurization, where the system fan is reversed to blow outdoor air into the soil. Passive soil depressurization is also addressed, with passive systems, natural phenomena (including the indoor vs. outdoor temperatures and the flow of winds over the roofline) relied upon to provide depressurization instead of a fan. The document focuses on the retrofit of radon reduction methods into existing houses as distinguished from the incorporation of radon-resistant features into new houses during construction. The document addresses all variations of the soil depressurization approach, including sub-slab depressurization, drain-tile depressurization approach, including sub-slab depressurization, drain-tile depressurization, block-wall depressurization, and sub-membrane depressurization in crawl spaces.
