All penetration for services and drains should be sealed using preformed top hats, sealed to the radon barrier with butyl radon tape. Airtight seals should be formed around all service entry points. Top Hat Units are available for sealing around pipe entries. The base of the pre-formed unit should be sealed using radon butyl tape. Where there are pile caps or stanchions, advice should be sought.
