Types of building stone

In general, stones are divided into different types in terms of design, color, material, and quality, and the description of some of the most practical ones includes:

1. Marble
Marble is a kind of white and transparent calcareous metamorphic stone that is resistant to weather conditions to a good extent, but due to the possibility of weathering against weather conditions and the possibility of becoming cloudy under light radiation, it is mainly used inside the building. Usually, this stone is cut parallel and perpendicular to the layers, which creates an eye-catching beauty.

Also, the variety of colors, the ability to cut and polish is one of the unique features of this stone, which has classified it as one of the expensive stones.

2. Granite
Granite is one of the igneous rocks of volcanic origin, which has considerable hardness and strength. It is interesting to know that this stone is known as one of the best floor coverings for buildings, and at the same time, it can be used inside the exterior of buildings, especially in very cold areas, as a durable stone with low water penetration and Expansion and contraction are used sparingly.

On the other hand, due to the very reasonable price of this stone, its durability and the stability of its color, it can be considered as a very ideal facade stone.

3. Travertine
Travertine stone is one of the stones that is known as one of the best examples used both in the exterior of the building and in the interior decoration of the building.

The use of travertine stone is usually in building facades, flooring, stairs, toilets and other cases. Among the most famous travertine stones is Haji Abad travertine, which is known all over the world. This stone has a cloudy, windy and wavy design and has excellent cutting ability.

Haji Abad stone is a very ideal option for use in facades of buildings and hotel lobbies. Regarding the features of this product, it can be said that due to the high porosity of this type of stone, it can be used as a natural insulator.

Compared to granite, travertine has a more reasonable price, so its use is more common.
