Desjoyaux Piscines from La Fouillouse, France, is the biggest producer of swimming pools in Europe. Besides the actual pool design and fabrication itself, the full package includes concrete edging blocks manufactured in a separate production hall using the wetcast method. When it comes to concrete, Desjoyaux Piscines has relied for some 3 years past on the long-standing experience of Sylvain Adam from Beton Stone Consulting (BSC), Etzling, (Moselle) close to the German border. Extensive modernisation work was recently carried out at the production facilities which were re-equipped, amongst other things, with a new concrete mixer from Kniele Baumaschinen GmbH, Germany.
