Over time, cracks may develop in the floor covering and/or in the transition between the floor and walls. In the (often) small bathrooms from this period, this leads to water penetrating the concrete floor structure – and in the long term, corrosion in those supporting iron elements that are not rustproof.

If the cracks are detected in time and repairs can be carried out before the cracks become noticeably developed, it will sometimes be sufficient to replace or repair the floor covering and make the transition watertight. Otherwise, the supporting iron elements must be completely uncovered and replaced or partially uncovered and treated/reinforced.
