A Guide to Sandstone
Sandstone is a sedimentary rock. Clastic deposits of sand sized grains of quartz, often with Feldspar, Mica and other minerals, formed by weathering of quartz rocks and deposited by water or in deserts formed by wind. Grain size ranges from 1/16 millimetre to 2 millimetres in diameter. Sandstone is a proven durable material. The most common colours are tan, yellow, brown, red, grey and white.
Sandstone has been used for building for thousands of years from the Luxor temple in Egypt to Taj Mahal in India. Many churches and monuments in the UK as well as large commercial buildings and homes use sandstone.
Sandstone comes from many places all around the world and is a widely used as a material for construction. Sandstone is used for pillars, coping stones, memorial stones, sculptures, lintels, sills, external walls, flagstones, paving such as York stone, flooring, fireplaces, patios and many other architectural applications.
Selecting Sandstone
Always buy from a reputable stone supplier or fabricator. Check for any cracks, seams or spalling. Sandstone is naturally porous so sealing is essential for stone used externally. There is a British standard of quality conformity and you should ask your supplier about this. The harder sandstones tend to be darker in colour, which for patios may be more appropriate, as weathering can affect the stone especially frost.
Although the main components of sandstone are chemical resistant that’s not true of the binder that cements the particles together, such as calcium carbonate, that is broken down by acids.
High pressure jet washing is not recommended and it’s not uncommon to see thin layers of the stone break away as a result.
