Established in San Carlos, since 1947, Calstone has serviced Northern California for more than 70 years. Calstone has four manufacturing and distribution facilities in operation, Galt, Gilroy, San Martin, and Tracy.
A Mediterranean sense and feel are achievable with our Classic Cobble design. Subtle texture, rich colors, and a variety of installation patterns create this old world appearance. Design possibilities are limitless combining our multi-sized cobbles and a recipe for our stock color blends. Available in four complementary sizes, these paving stones add warmth and texture to your patio, walkway, or driveway.
Antiqued Cobble (River Rock) has a rustic cobblestone impression. These unique paving stones are for those that want to create the natural look and feel of a surface that has been aged by time and the elements.
Reproducing the natural look and feel of stone, Calstone strives to create random fractures, chips, scratches, broken edges, and corners, in the manufacturing of our antiqued products.
Our Quarry Stone selection mimics what the Earth geologically provides us. From a natural stone origin, we created seven distinctive blends each using multiple tailored colors. Quarry Stone is formed in four different shapes each palletized separately to offer you complete control of the style and patterns you wish to install.
Our new Versailles Series incorporates the natural stone appearance of Quarry Stone into larger sizes. These larger sized stones are ideal for patios, walkways, pool decks, and other large pedestrian areas. Because of the large format, Versailles Series cannot be used for vehicular traffic. Versailles can be used as permeable non-vehicular residential applications.
Design flexibility and traditional pattern layouts make the Mission series of a timeless classic. Complex accent banding or simple patterns, Mission pavers allow endless options of color and form. Calculated to install together or separately, the Mission series paving stones will conform to your imagination.
Our antiquing process creates an aged appearance that brings an old-world charm to any outdoor project. Reproducing the natural look and feel of stone, Calstone strives to create random fractures, chips, scratches, broken edges, and corners, in the manufacturing of our antiqued product paving stones.
Simple, smooth, and beautiful. Replicating saw-cut stone, Antiqued Flat Top balances the modern and rustic look with non-chamfered edges, narrow joints, and light antiquing. It is also featuring large-scale units perfect for patios, pool decks, and walkways. The large-format cannot be used for vehicular traffic.
