Divers’ tower TODI

In 2016, Europe's largest indoor diving centre was opened on the old mine site in Beringen. A unique concept, whereby old coal basins had been converted into a wonderful underwater world. Staco manufactured the grids and steps as well as the floors around the basins.

In Beringen, in the Province of Limburg, a unique project has been realised last year, involving 2 old coal basins, which were converted into the largest indoor diving centre in Europe.

The unique diving concept comprises an indoor, heated diving basin with a diameter of 36 metres, a depth of 10 metres, and containing 6,200,000 litres of water. The fauna is magnificent: some 1,500 colourful, tropical fresh-water fish populate the basin. As assigned by Hercon NV in Houthalen-Helchteren, different variations of gratings have been manufactured by Staco.

The exterior wall of the building was provided with over 300 m² balustrade gratings, version RR 30-2, with a mesh width of 66 x 33. These hot-galvanised gratings were reinforced by means of an extra thick edge of 30 x 5 mm and welded-in plates for mounting purposes. For the 2 large spiral staircases, 128 steps were manufactured, version AP3-50 MAW.

The spiral staircases were cladded as well: with RR 30-2, mesh width 66 x 33. In this case, the 185 m² of gratings were rolled. Surrounding the large basins, 264 m² of walkway gratings, type RR 30-3, mesh width 66 x 33, were installed. These segment gratings were provided all around with the same balustrade gratings as the exterior of the building.

In short, it was a unique project with many facets, in which multiple forms and applications of gratings have been used.
