The sandstones are among the most porous consolidated rocks, sedimentary quartzite although some may have less than 1% voids. Depending on the size and arrangement of empty spaces or pores, the sandstones show varying degrees of permeability.
quality sandstones are durable. The rock has a good fire, and in this respect, is superior to most of the rocks used for building.

Uses of sandstone
This resource is characterized by its lajosidad. This property is a feature that encourages the use of this rock in the construction applied on floors, sidewalks and walls. usually presents no lajeables also blocks that can be exploited for the construction of fences or walls.
also for having low cohesion, ie little compaction, sandstone allows its use in another application, making handicrafts by modeling the rock
