Types of stones for building

Stones are materials found in nature as large blocks of rock within the earth. For example, marble, granite, and slate. We can obtain them from quarries.

We can also find them in different sized granules and fragments, such as sand and gravel.

Marble and granite have high density and high resistance to environmental conditions. They are used on floor and walls.

Slate is hard, dense and compact which makes it waterproof. It is mainly used to cover roofs and as paving stones.

Sand and gravel are used to make asphalt (a mixture of tar, sand and gravel).
