Prevent concrete slabs - they are often more expensive than natural natural stone, will fade over time and end up looking fake. American indian Sandstone has dominated the paving slab market for a long time as it is cheap, natural, accessible and looks good. Cheaper Indian Sandstone is not always the bargain it appears as it is thinner, or poorer quality and more porous causing leaching on the minerals in the mortar on the top surface of the stone. There are some inexpensive granite slabs currently available that make a wonderful surface only slightly more expensive than Indian Sandstone. The more expensive options are Travertine, You are able to stone, Basalt, and Marble.
