Radon mitigation and fresh air supply combined?
Hello, if a home tests positive for radon and also would like to have an ERV & fresh air ventilation system, can these things be combined? In other words, can I tie a subslab depressurization system into a the ERV and fresh air system? Alternatively, is there any evidence that a moderate radon problem (4.1) can be mitigated with fresh air ventilation only?
Furthermore, if the radon test came back positive prior to any air sealing or insulation upstairs, is it logical to think that the radon value would increase once the home is further sealed up? The foundation is hollow concrete block with a poured floor, from 1946. It’s a mostly finished basement, but there is one area in the floor where the concrete is broken up for an unknown reason. Are there any basement air sealing techniques that could help with both thermal and air quality control?
Thanks for any info.
