contaflexactiv joint profile
The CFS/CFE joint sealing profiles are specially designed for the application in precast walls with a core thickness of ≥ 12 cm and meet the high demands for effective waterproofing against hydrostatic pressure. The system consists of galvanized folded profiles coated with bentonite, with excellent active sealing effect and ease of handling during installation and in providing the butt joints. The water that penetrates along the profile contacts the contaflexactiv coating and activates the swellable bentonite to form a highly impervious barrier.
The coating of the metal waterstops consists of highly swelling bentonite.
