Sandstone Description: Sandstone is a type of sedimentary rock formed of gritty sand grains and is available in a variety of colours. Sandstone paving is available in a range of different textures, often relying on secondary processing to achieve these finishes. Smooth, Sawn Sandstone This sandstone has a level, smooth surface and most often, machine cut edges to give a sharp, clean appearance suited to modern, contemporary styles. The surface texture can be smooth to the touch (honed) or have a slightly rough sand-blasted texture to provide non-slip qualities. It is usually also produced in a calibrated thickness where the variation in the thickness of the slab is kept to a minimum to ease laying. Sandstone Colours: Sandstone is available in a wide range of colours, some subtle and some vivid. The ranges comprise of a selection of core colours combined with subtle contrasting shades, and the balance of shades can vary between batches of even the same stone due to different seams in the stone quarry occurring over time. The colour intensity increases when the paving is wet. Most brands offer the same range of colours with slightly different names. BE AWARE that not ALL sandstone is the same quality - some unknown brands may not have been tested for suitability in the UK climate and may crack during cold weather.
