Minimum System Requirements
At a minimum, radon mitigation systems must meet the following requirements:
Health, Safety, & Economic Considerations
Radon mitigation systems, specifically Active Soil Depressurization systems must be designed with great consideration to the health and safety of the building’s occupants. Think about it: these systems draw radon gas and RDPs from below the slab where levels are likely to be exponentially higher than the indoor air. For this reason, all ASD systems should be designed to prevent back drafting from the fan housing or vent pipe system into the conditioned space of the building envelope. In addition to radon, other dangerous or flammable soil gases exist such as methane, the greatest problem for buildings situated on or near landfills. Pesticide residue can also be vaporized especially in highly concentrated areas such as buildings situated on land previously used for farming.
Prior to starting any mitigation work, radon contractors should do the following in due diligence to protect the client’s health, safety, and economic well-being:
Perform a thorough building investigation and diagnostic tests necessary to minimize expense and ensure efficiency.
