Chalon grey limestone pavers: A consistent light to medium grey stone with occasional shells and a cloudy appearance. Chalon antiqued tumbled natural pavers have light ageing to the edges and surface creating a chalky appearance with rustic charm. These are supplied in 150 x random lengths x 20mm. These durable stones work for both classic or modern settings and can be for interior or exterior use. The tiles for inside are only 20mm thick. Pool copings and treads can be produced in the same material. These also perfectly complement our Chalon grey limestone floor tiles and are suitable for use with underfloor heating.
