Sandstones can be soft or rough in texture, depending on the ingredients.
– Sandstones are resistant to freezing and weathering.
– Water absorption in Sandstone is relatively high due to its high porosity.
– Sandastone silica has good resistance to acidic environments. But its calcareous type has little acid resistance.
– Sandstone has a high flexural strength which makes it less durable. As a result, the structure will eventually become lighter.
Sometimes, despite the use of high quality stone in the facade of the building, other causes cause the stone to fall.
