Desjoyaux, a pool manufacturer, is investing 4.5 million euros in its production facility in La Fouillouse, France. The investments include buying a new press and automating liner production, as well as developing a DIY pool kit and floating pool. Desjoyaux also plans to launch a self-assembly pool kit for 7,000 euros as it seeks to capitalize on the growing do-it-yourself market while maintaining its reputation for concrete pools with a 10-year guarantee.
