CORDEK of the UK says its two-way spanning polypropylene waffle moulds can turn ordinary ceilings into an aesthetically-pleasing architectural feature.
''That seems to be the view of an increasing number of designers who are now specifying these moulds as much for their high-quality finish, as for the considerable cost savings they offer against traditional solid floor construction,'' says Warren Bungey of Cordek, which specialises in innovative product solutions for the building and construction industries.
He continues: ''One-way spanning polypropylene trough moulds, which provide a good industrial quality finish, are equally popular as a major project in Qatar confirms. In total, some 16,000 moulds are currently being used in the construction of the new Weill Cornell Medical College in Doha. The joint venture contractors for this prestigious development are Al Darwish Engineering and Contrack International.''
'While these trough and waffle moulds were originated by GKN, they are now manufactured and marketed by Cordek of England. The injection-moulding process used ensures a consistent product standard," Bungey says.
"Long recognised as one of the most cost-effective ways of constructing in-situ ribbed concrete floors, our range of 11 standard mould sizes is suitable for a wide variety of buildings and accommodates most design requirements," he says.
Elaborating on the benefits, he says: "Whether it's one-way spanning (troughs) or two-way spanning (waffles), the result is a lighter floor, saving up to 60 per cent of concrete compared to solid floors and with commensurate savings on the steel reinforcement, columns and foundations. Our technical department is of course always on hand to provide full back-up support."
''Fully proven in the Middle East and other countries throughout the world, the hard-wearing polypropylene construction allows up to 100 reuses per mould. High stockholdings are held to ensure short lead times.''
