Saint-Astier

‍

Founded in 1912, the family company Saint-Astier is today the largest independent French producer of world-famous lime. The unique composition of Saint-Astier limestone makes it possible to produce - without mixing or selection - a natural lime that has the ability to harden under water and recarbonate in contact with air. These hydraulic and aerial properties make it a lime with exceptional mineralogical properties, unchanged since the first quarrying, 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-housing.

Since 2003 Reynchemie is exclusive distributor in the Benelux of the lime products of Saint-Astier.
