Sandstone is a sedimentary rock made of grains of sand (defined as 1/16 mm to 2 mm sized particles) that have been naturally cemented together. Grains in sandstones are unfused, and some of these grains can be dislodged by rubbing across the rock. Sandstone represents ancient stream, deltaic, or beach deposits.

Then, the water content reaches a constant level after several hours. The natural absorption water content by weight for yellow sandstone is approximately 7.72%, while it is only 1.5% for the grey sandstone at the final stable state. The water content increases with increasing porosity and is a typical exponential function of the soaking time.
