Introduction: Natural stone, a material with a long history and lasting beauty

Natural stone is not just a piece of stone, but it somehow carries the identity card of the earth and the history of its formation. The use of stone in construction dates back thousands of years and reflects the strength, durability and beauty of this valuable material.

The role of stone in ancient civilizations

Take a look at ancient monuments; from the magnificent temples of Greece and Rome to the Great Wall of China, you will see traces of stone everywhere. This shows that man has recognized the value and functionality of stone from the very beginning and has used it to build lasting buildings.

Advantages of using natural stone in construction

Why, despite all these new materials, is natural stone still popular in construction? Well, there are many reasons. In addition to its unique beauty, natural stone has high strength and durability, is resistant to weather factors, is good thermal and acoustic insulation and, finally, adds value to the property.

The unique variety of natural stones

You may think that stone is just a kind of hard and gray material, but the world of natural stones is much more diverse than that. From hard and durable granite to luxurious and shiny marble, from travertine with its special holes to limestone with warm colors, each of these stones has its own characteristics and uses.

Main categories of natural stones used in construction

In order to better familiarize ourselves with the types of natural stones, we divide them into three main categories based on how they are formed: igneous rocks, sedimentary rocks, and metamorphic rocks.

Igneous Rocks: Born from the Earth

This group of rocks is formed by the cooling and solidification of molten materials inside the earth (magma) or molten materials coming out of volcanoes (lava). The structure of these rocks is usually dense and resistant.

Granite: Unparalleled strength and wide applications

You have probably heard the name granite a lot. This stone is one of the hardest and most resistant types of igneous rocks, and because of this high strength, it is used in many parts of construction; From foundations to flooring and building facades. Granite is usually found in grains and in a variety of colors such as gray, pink, black and white.

Basalt: A durable black stone for heavy projects

Basalt is another type of igneous rock that is usually dark in color (black or dark gray) and is very durable. Because of these characteristics, basalt is mostly used in heavy projects such as road, bridge and dam construction, but it is also used in building construction for flooring and exterior facades.

Diorite and Gabbro: Hard and durable options

Diorite and Gabbro are also from the igneous rock family and have similar characteristics to granite and basalt, except that they may differ slightly in color and texture. These stones are also used in various parts of construction due to their hardness and durability.

Sedimentary Rocks: Layers of Earth’s History

This group of rocks is formed by the settling and sticking together of various particles such as sand, gravel, mud, and the remains of living organisms over long periods of time. The structure of these rocks is usually layered.

Limestone: A Soft Material with a Variety of Uses

Limestone is one of the most common types of sedimentary rocks, consisting of calcium carbonate and usually light in color (white, cream, or light gray). Limestone is relatively soft and easily cut, which is why it is used in construction to build walls, facades, and even cement production.

Sandstone: Natural Beauty and Resistance to Erosion

Sandstone is also a type of sedimentary rock that is formed by the sticking together of sand grains and usually has warm colors such as brown, red, and yellow. Sandstone is very popular for building facades and landscaping due to its natural appearance and resistance to erosion.

Travertine: A stone with unique and attractive holes

Travertine is also a type of sedimentary rock that is formed from the deposition of minerals in hot springs and is known for its holes and special texture. Travertine usually has cream, beige and brown colors and is used in construction for facades, flooring and wall coverings.

Conglomerate and Breccia: Composite rocks with a special appearance

Conglomerate and breccia are also types of sedimentary rocks that are formed by the adhesion of larger pieces of rocks and minerals and have a relatively heterogeneous appearance. These rocks are mostly used for facades and decorative works.

Metamorphic Rocks: Changed over time

This group of rocks is formed by the deformation of igneous or sedimentary rocks due to high pressure and heat inside the earth. These changes cause the structure and texture of the original rock to change and a new rock with different characteristics is created.

Marble: Splendor and beauty with high polishability. Marble is one of the most luxurious and beautiful types of metamorphic stones, formed from the metamorphism of limestone and

Various uses of natural stones in different parts of the building
Now that we have become familiar with the main types of natural stones, let’s see in which parts of the building each of these stones is most used:

Foundation: A solid base for the building
Foundation is the most basic part of any building and must be made of strong and durable materials.

Suitable stones for foundation
Igneous stones such as granite and basalt are the best option for building foundations due to their high strength and resistance.

Walls: Both strength and beauty
In addition to bearing the load of the building, walls also play an important role in its beauty and insulation.

Suitable stones for load-bearing and non-load-bearing walls
For load-bearing walls, resistant stones such as granite, basalt and some types of limestone are usually used. For non-load-bearing walls, lighter stones such as travertine and sandstone can also be used.

Facade: A protective and eye-catching covering
The facade of a building is the first thing seen from the outside and plays an important role in the overall beauty of the building. The facade must also protect the building from weather elements.

Suitable stones for interior and exterior facades
For interior and exterior facades, various types of natural stones such as marble, granite, travertine, sandstone and limestone can be used. The choice of stone type depends on taste, budget and weather conditions of the region.

Flooring: A durable and beautiful surface for traffic
In addition to being beautiful, the flooring must also be resistant to heavy traffic and wear.

Suitable stones for flooring in different spaces
For flooring in high-traffic areas such as hallways and reception areas, hard stones such as granite, marble and quartzite can be used. For other interior spaces such as bedrooms, softer stones such as travertine and limestone can be used.

Stairs: A stylish connection between floors
In addition to being functional, stairs can also be an important decorative element in a building.

Suitable stones for stairs
Strong and durable stones such as granite, marble and quartzite are usually used to make stairs. The surface of the stairs should be properly polished to prevent slipping.

Roof: A durable and insulating covering
The use of stone for roof covering is not very common, but in some specific areas where stone is abundant and there is a specific architectural style, thin and durable stones such as slate are used for roof covering.

Suitable stones for roof covering (mostly in specific areas)
Slate is the best option for roof covering in specific areas due to its layered nature and resistance to weather.

Landscaping: Creating a pleasant atmosphere in the outdoor environment
Natural stones play an important role in beautifying outdoor spaces such as yards, gardens and sidewalks.

Suitable stones for sidewalks, yards and gardens
Different types of stones can be used for landscaping, such as granite, basalt, sandstone, limestone and rubble. The choice of stone type depends on the landscaping style and the amount of traffic.

Factors affecting the choice of stone type for different applications
Choosing the right type of stone for each part of the building depends on various factors that we should pay attention to:
