Butt-joints of precast element walls must be designed according to the guideline for watertight structures as a controlled crack cross-section.
The Fradiflex® element wall sealing system for joints and corners causes a controlled crack at the joints of the triple wall and reliably seals the precast element joint. No additional sealing measures are required. (White tank)
The stable design of the precast element controlled crack elements significantly reduces the assembly times. The Fradiflex® metal water stop only needs to be fixed at two points and there is no need to attach it to the shell.
The combination of Fradiflex® metal water stop and element wall (precast element) with Fradiflex® roll (floor slab) is the optimal solution for pressing water.
