ERV Radon Mitigation for a Home with an Inaccessible Crawlspace

Traditional sub-slab depressurization was not a viable option for this home because concrete covers only half of the foundation, while the remaining section contains an inaccessible crawlspace. After evaluating the home's layout, an Energy Recovery Ventilator (ERV) was identified as the best approach to help address radon and improve indoor air quality.
