Some €1.4 million of investments have been spent over three years on the renewal of the site's mobile equipment.
The quarry's granulates are used in the concrete on the high-speed railway between Tours and Bordeaux, and it produces 70,000tonnes of ballast/year and supplied 650,000tonnes of material for the Midi-Pyrénées Railway between 2007 and 2012. The project represented up to 50% of its activities in certain years.
The quarry has ISO 14001 environmental management certification and conforms to OSHAS 18001 security standards.
Around €1.3 million will be invested in the site in 2013 to increase its crushing, washing and sifting capacity.
