Saint-Astier

‍

Founded in 1912, the family business Saint-Astier is today the largest independent French producer of world-renowned lime. The unique composition of Saint-Astier limestone makes it possible - without mixing or selection - to produce a natural lime that has the ability to harden underwater and to recarbonate in contact with air. These hydraulic and air-technical properties make it a lime with exceptional mineralogical properties, unchanged since the quarry's first reclamation, and unique in Europe. With a team of 140 men and women, Saint-Astier produces and distributes hydraulic natural lime, formulated lime and technical mortars for heritage restoration, renovation, new construction and eco-homes.

Since 2003, Reynchemie has been the exclusive distributor of Saint-Astier's lime products in the Benelux.
