Underfloor extraction of radon

Floor type: Suspended floor

Sometimes extracting air from the sub-floor cavity (active underfloor radon extraction) has better results than ventilating the airspace, depending on the location. The radon systems used for under-floor ventilation can be used to do this. However, ventilating a sub-floor space is always the starting point for radon remediation of sub-floor voids.
