12 Steps to install radon mitigation in a day
Radon mitigation starts with reviewing the building structure and previous radon measurements.
- Walk Through : to determine the potential radon entry routes and establish the appropriate mitigation strategy.
- Communication Tests: If a sub-slab depressurization system is considered as possible choice of systems then communications test should be performed if sub-slab soil conditions are unknown.
- System Goals and Design : A radon reduction system shall be designed as an integral part of a dwelling, minimize noise and aesthetic impact on the structure.
- For SSD system piping PVC or ABS shall be used
- Radon Collection point: A min of one half cubic foot of sub-slab material shall be excavated at each suction point.
- Number of Suction points shall be determined by communication available throughout the sub-soil, the number of separate slabs that are significant radon sources and do not communicate with other slabs.
- Fan shall be sized to provide adequate vacuum and air flow characteristics for each mitigation installation.
- Exhaust location shall be at list 12″ above the roof line and at list 10 feet from any vent, window, or openings that are less then 2 ft below the exhaust point.
- Electrical connection: if the fan capacity exceeds 50% of the circuit capacity, then fan shall be wired with a dedicated circuit. There shall be electrical disconnect for the fan for homeowner and service use.
- Sealing cracks and non-functioning openings that emanate soil gas.
- Open cinder and concreate block cores and voids should be sealed
- System Monitoring: Each depressurization system shall include a vacuum indicator, a pressure U-tube manometer .
In conclusion, radon mitigation system installation is a complex process. It requires experience and knowledge of hazardous materials, basic building design, electrical wiring, construction materials. In addition, you should understand building pressurization/depressurization conditions and measurement procedures, radon reduction techniques. A licensed and experienced radon mitigation provider can install one SSD mitigation system in about 8 hours. For a homeowner, without proper tools and knowledge, this project can be a challenging, but rewording task.
