Buying building stone is one of the most important actions during construction. Many people make the purchase without knowing the exact information about the stones and the important points in buying stones, and sometimes they have problems while working. In this article, we have discussed the important points in buying building stone so that you can buy stone with a high level of knowledge:
Stone compressive strength
The compressive strength of stone is one of the most important points when buying stone. Your stone should have appropriate pressure resistance according to its location and use. Before buying the stone, we should see in what space and place and with what kind of application the stone is going to be installed in order to choose the appropriate use of the stone. So that the stone is not damaged in the process of time and use. because the maximum pressure caused by the stresses and settlements of the building in the facade is 300 kg/cm. It is suitable for the floor of commercial and residential units and the floor of different parking lots. The compressive strength of the floor stone of residential units is at least 500 kg/cm, and 270 kg/cm for office and commercial complexes, and 900 kg/cm for the floor of the parking lot and area.
Rock water absorption
The amount of stone water absorption is another factor and important points when buying stone. Your stone should have suitable water absorption according to its use. All stones absorb water, but their absorption rate is different, for example, limestone has high water absorption and cannot be used in places exposed to moisture and dirt because they are highly stainable and rot due to atmospheric conditions and moisture. they become
Facade: The amount of stone water absorption in the exterior should not be more than 2%, and in the interior, the amount of water absorption is not very important, and for this reason, in the interior of the building, because it is exposed to the weather and All building stones can be used in this part of the building.
Floor stone: The amount of water absorption in paving stones depends on the type of use of the building. The high water absorption rate of the stone will cause the stone to become stained. Therefore, stones with low water absorption will be a suitable option for paving stones.
Application of stone
One of the important points when buying stone is to consider its use. For example, if the stone you choose is for the exterior of the building, then you should choose travertine, granite, or crystal (porcelain) stone.< br>
Because the mentioned stones are resistant to sunlight, cold and heat and will not lose their color due to atmospheric conditions.
Floor stone: The internal paving stone can be different depending on the type of use of the building. The best option for residential units is marble, crystal (Chinese) stones. Granite, crystal and marble stones are suitable for office and commercial units. The paving stones suitable for the parking lot are granite stones, and the paving stones suitable for the area and sidewalks are travertine and granite stones. Of course, I must note that the paving stone of the parking area must have a large diameter.
The shape and size of the rock
If your reception hall is large, you can use slab stone dimensions and large sizes such as 80x80 and 100x100 because less joints are visible and the stone is seen as a whole. And if your space is small, you should use small size stones like 40x40, 40x20. And if your living room is rectangular, you can make your space lighter with the dimensions of long rectangular stone, such as 40x80, 30x60. So, look for a stone that matches the shape and size of your space.
Save Stone
Choosing a stone in a large area should have a suitable storage and be able to supply the required stone for the project. Selection and purchase of stone for large projects should have a high reserve. And knowing the cycle of mining to production is very important. Because some stone mines are located in areas where there is no possibility of operation and traffic in some seasons due to their geographical location, and in other words, the mine is closed. Some mines do not have adequate storage and your project may remain incomplete.
Price of stone
Selection and purchase of stone should fit your budget. There are different types of stones and there are many similar stones. Some stone mines have a high price due to their high demand and export, but there are similar stones at a lower price than other mines that can replace such stones. Another reason affecting the price of stone is its size and type of processing, so that stone processing by saw and slab method has a higher price than the peak processing method. Therefore, if you don't have enough budget to buy stone slabs, you can replace smaller size stones.
Type of stone processing
One of the most important points in choosing and buying stone is the type of stone processing. One of the common mistakes in the stone market is that stone is not produced but processed. Stone is a natural material to which no additives are added, and natural stones are cut in stone factories and processed depending on the type of order (sanded, leather, honed, sandblasted, hatchet). The type of processing such as (cutting precision, gonia, resin and epoxy, stone thickness, sub-stone, stone sort, etc.) can have a direct impact on the stone price.
Stone color
To choose and buy your favorite stone, be sure to pay attention to its color theme, stones are a world of colors and designs, each of which has its own characteristics. All stones are not stable in color and some stones will lose their color in sunlight, so not all stones can be used in sunlight. Marble, marble, and limestone will lose their color over time when exposed to sunlight, but travertine and granite are more resistant to sunlight.
