Butt-joints of 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 element joint.
In addition to improvements to the design, modifications considerably facilitate the ordering process and on-site handling. The standardized product now consists of 2 standard length units and 5 standardized components.
The waterproofing membrane must be able to withstand cleaning before the concrete is poured, which is an important factor in the selection process. Zemseal® has been extensively tested for cleaning behaviour.
The sealing of the construction joint between floor slab and wall can be done for example with a metal water stop or with PVC waterbar. The simplest and safest solution is the one with coated metal water stop.
