Natural Stone Flags
These are the best products for paving. Limestone, Sandstone and Granite are examples of natural stones, they are durable, beautiful and maintain their colour & finish over time. There is a wide range available in terms of textures, sizes, styles and colours. It is more labour intensive but worth the extra investment. For a driveway, the thickness of the natural stone must be at least 50mm to be driveable and for a patio a thickness of 20-30mm is adequate.
