contaflexactiv joint profile
The CFS/CFE joint sealing profiles deliver superior protection against hydrostatic pressure in precast walls with a core thickness of ≥12 cm. Featuring galvanized steel profiles coated with highly swelling bentonite, this system ensures an active sealing effect, safe overlaps, and easy installation.
The Benefits:
Activ bentonite sealing system
Safe active overlaps
Easy and fast installation
Water pressure resistance up to 5 bar
Tested for joint expansion of up to 0.5 mm
General building authority test certificate (abP)
Tested for water pressure resistance up to 5 bar and joint expansion up to 0.5 mm, CFS/CFE profiles provide long-lasting security and certified performance. 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.
