Radon mitigation, or radon abatement, is the practice of reducing radon levels to below the EPA action-level of 4.0 pCi/L.
Mitigation usually involves the installation of a specialty radon fan piped from underneath the foundation to above the roofline. This method, known as sub-slab depressurization, aims to create negative pressure beneath the foundation, effectively reversing the flow of natural soil gases and preventing them from entering the home.
