Twin-wall construction is an increasingly popular alternative to cast-in-situ construction. Safe and simple sealing systems are also required for these structures. The guideline for watertight structures requires that the vertical joints of element Walls must be controlled crack joints.
Fradiflex® metal Water Stops for twin-wall sealing are very stable and they therefore do not need to be fixed at the element wall, but they are simply connected to the horizontal seal between base and wall. Fixing of the upper metal water stop ends is only required shortly prior to concreting using reusable fixing angles. No additional fixing means are required.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Max Frank is consulted before specifying.
