Prof. Barbara Vanderwee of Brussels approached us to ask whether we could produce the new façade elements needed for restoration work on the Coovi Elishout in Anderlecht, a school building dating from 1948. The existing cladding had been badly damaged by frost. The Flemish Community Commission asked Mrs Vanderwee for advice due to her expertise in the field of restoration and the re-employment of valuable historical buildings. Our assignment rapidly expanded to include all the cladding for the facade: 50,000 strips, 12,000 tiles and 20,000 moulded pieces consisting of more than 50 different models. The need to produce large moulded pieces by slip casting gave the company the opportunity to extend its expertise. Not only did the glazed elements have to seamlessly match the original materials, the clay mixtures used also had to be of the highest standard so as to comply with the established quality requirements especially with regard to frost resistance.
