Fradiflex® metal water stops are supplied with a special adhesive coating on one or both surfaces. The coating forms an excellent bond with fresh concrete to reliably seal construction joints. Jointing of successive lengths is easily achieved by simply overlapping the two lengths by 100mm and pressing together. A range of purpose made accessories including mounting clips and an expansion joint connector are available for easy and rapid installation. The two-part protective film to the coated surface is removed individually prior to each pour.
Available with a special adhesive coating on both sides, Fradiflex® Premium is supplied in coils or straight lengths. The double-sided coating strengthens the bond with fresh concrete and provides for additional sealing security.
Available with a special adhesive coating on one side, Fradiflex® Standard is supplied in coils or straight lengths, with or without an integrated fixing angle. The coated surface must always face towards the water retaining side.
The Fradiflex® element for controlled crack joints provides an uninterrupted seal between walls and bases/slabs. Additionally, elements for controlled crack joints are used in the concreting of large wall sections.
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.
