Active Depressurization
In cases where the seal is not effective, active depressurization system may be required. This technique is to pick up the radon directly under the slab and vented to the outside. Improperly installed systems can stop working after a year or two and then all over again.
Beware therefore installers of air exchangers or other ventilation systems because, although these can be beneficial to the quality of indoor air, they could have the opposite effect to that desired for the radon.
