WHAT MAKES DSM PRODUCTS STAND OUT FROM THE CROWED. DSM sandstone products take you back in time to an era of class, prestige and quality. Decorative Stone Masonry South Africa ( DSM ) , is a premium manufacturer of masonry sandstone blocks, retaining walls, and landscaping products. Our products possess the appearance and feel of genuine sandstone, manufactured with light coloured sand and white cement.. The aggregates used for the manufacture of these units does not exceed 3 mm, which results in a natural sandstone appearance. All products are manufactured in accordance with SANS – 1215 Concrete Masonry Units. Our range of bolstered products are individually hand crafted, allowing each unit its own character as no two blocks are identical. Our technology originates in Australia, and these advanced manufacturing techniques have been incorporated in our locally based factory in Gauteng. Our products have been mistaken by geologists as authentic natural sandstone. |

DSM Masonry products are hollow, improving the thermal properties of the structure. Hollow blocks use less material Per M 2 and weighs less Per ton than conventional brick work, reducing material and transport required for the building Per M 2.
As with all DSM materials, DSM blocks are formulated using high volumes of fly ash, a recycled resource that is in abundant supply wherever coal is burned.
