Is sandstone porous.

Bluestone is porous, being a sandstone and all. This means in the wrong application trapped moisture can cause troubles such as delamination and cupping. The most common situation where we see failure occur is when Bluestone is wet laid and water gets trapped under the stone.Economical natural sandstone tiles,sandstone gem,sandstone under microscope,sandstone construction,red sandstone tiles,gold found in sandstone,sandst,crushed stone sand,sandstone structure,sandstone rock gardenIts outside walls are made of a type of sedimentary rock called sandstone.
