Andesite is a igneous rock resulting from a volcanic eruption, which has a fine grain in various shades, from brown and purple to gray. Having a uniform structure, andesite is a very hard building material.

General technical characteristics :

• Water absorption: 2,40 %
• Compression strength: 0,1 g/cm2
• Dry compressive strength: 120N/mm2
• Compressive strength after 25 of freeze-thaw cycles: 100 N/mm2
• Mechanical shock resistance: 3,5 N/mm2

fitting:

Both adhesive-based assembly, as well as screed mounting can be used.

uses:

Andesite is also used as a building stone for paving roads. Due to its hardness, can be used for sidewalks, court, parking, plinths or facades.

Availability:

Andesite can be delivered in the form of ballast, plywood or cubic stone.
