This London Graphite porcelain is a dark charcoal grey to black colour with a slightly rivened surface. Very stylish and contemporary! Perfect for “inside to out” projects, Porcelain paving can be laid on flat roofs, balconies, patios, paths, steps, swimming pools and driveways. Because it is non-porous, it is also stain resistant and does not need sealing like most other paving. What’s more, this is an ECO Sustainable product.
