Stone walls are a kind of masonry construction that has been used for thousands of years. Stone walls are usually made of local materials varying from limestone and flint to granite and sandstone. However, the quality of building stone varies greatly, both in its endurance to weathering, resistance to water penetration and in its ability to be worked into regular shapes before construction. Sandstone is very resistant to weathering, and we provide you with a distinct range of walling sandstones. Walling sandstones are available in different sizes, textures and colours.
