You can install radon mitigation system through the attic to hide the radon system from view and offer better protection from outdoor weather conditions.
Radon gas can also enter the livable areas above crawlspaces through the floorboards. If this is happening, the installation of a special vapor barrier is required.
Active soil depressurization systems vent radon gas by creating a vacuum in the soil below the foundation. We install an active radon vent fan.
The radon gas gets sucked through the system and it is vented to a safe elevation above the building. Such vacuum systems include:
- Block wall depressurization
- Drain tile depressurization – sump pump area
- Sub-membrane depressurization – below a vapor barrier
- Sub-slab depressurization – under cement slab flooring
