Spurgin has been focussing on innovation, sustainability and efficiency for decades – supported by its long-standing partnership with the Progress Group. The French market leader for conventional double walls and double walls made of concrete with a low CO2 content realises state-of-the-art circulation systems with the full-range provider for the precast concrete industry, as is currently the case in Mignières in northern France. The result is a new production line for the manufacture of wood-concrete elements consisting of 85% bio-based material – a pioneering project for the precast concrete industry, and not just for Spurgin.
