Granite is a magmatic rock and thanks to the fact that it contains large amounts of mineral compounds, it can gain different colours ranging from grey through green to black. It is commonly applied in construction both as basic and decorative material.

Its main advantages include:

• resistance to freezing
• resistance to acid rains
• resistance to solar radiation
• resistance to soaking

Sandstone is a sedimentary rock and is commonly used in construction.

Applications:

• windowsills
• facade plates
• railings
• columns
• fountains
• sculptures
• tiles

You have to remember that sandstone needs impregnation, what fully protects it against changing weather conditions.
