Carrière de Saint Denis 
Eruptive rocks quarry in the Sarthe departement (72)
Saint Denis quarry started in 1984. It was created to supply the local market which was poor in eruptive-based materials. Initially designed to produce about 400 to 500 000 tons of materials, their production has gradually increased to reach 1 million of tons today up to 1 600 000 tons for the past two years (2013 and 2014) when delivering the French railway “Ligne à Grande Vitesse Bretagne – Pays de la Loire”.
Production
Saint Denis quarry exploits a deposit of eruptive rocks (Gabbro or Dolerite) that they transform to produce aggregates mainly designed for roadworks and construction works. The deposit is homogenous. The petrographic quality of the various quarry faces is determined and recorded each year as the basis of the product traceability.
