5 factors that cause stones to decay

Stone is one of the natural materials extracted from the mountains, and the process of the various processes on which it is applied becomes a stone. Different types of stones affect most of the building stones, especially face stones. In fact, it can be said that natural stone is deteriorating over time. Various factors affect the stone, which can be prevented from many of them. Of course, many of the decay factors can’t be prevented or prevented from occurring. We will try to point out 5 of these factors.


One of the most important factors affecting the decay of the stone is rain water. The rainwater both physically and chemically affects various stones. Chemical agents generally act in two ways: stone decomposition, oxidation and hydration. Especially in industrial areas there are more acidic waters, and therefore can easily decompose stone. It is therefore recommended to use less in stone than industrial buildings. Both of these factors cause stones and cause many problems for this natural substance.

Regarding the physical impact, the building’s aging has been used in places where the rain is heavy on it, and this rain also dries with sunlight, and this happens as a routine occurrence; a series of tensions are created inside the stone, causing the stone to Split inside. These conditions are such that too many layers of stone may be removed in a very short time and the stone is degraded. Especially in cities where air pollution is high, acid rain can severely destroy building stones. To do this, it is attempted to use stone stones in which expensive stones are used in them, it is not a factor in the drying of rainwater and stony surface. Of course, this is rarely happening. It is suggested that high quality stones be used to avoid this problem.



One of the factors affecting the decline of stone is dew. In places of the world where the air is very cold and humid, dew causes stone to decay. The dew penetrates into the tiny holes and freezes after cooling. This kind of frost will cause cracks in the stone. In these areas, stones are generally used with very few porosity.


Another factor that causes stones to fall is wind. In places where the wind is burning heavily, the use of stony facades is recommended because of the strength of the stone, but this wind can bring a lot of wear to the stone. In fact, dust has dust particles that create erosion on the surface of the stone.

temperature changes

Temperature variations are one of the things that cause stones to decay. Expansion in the stone due to the high or low temperature as well as the contraction in it can cause a lot of problems in the stone resulting in stone deterioration. This occurs in stones with minerals with different volumetric expansion coefficients, since some of these particles tend to contract, and others become less expanded, which is why stone deterioration due to temperature variations It happens.


Growth is one of the other things that can be considered as a stone’s downfall. Plant growth can cause stone deterioration. This case occurs more often in stony floors in buildings located on the ground. The roots of the trees and weeds that are created around these stones cause the stone to deteriorate. In addition, when the plant is next to the stone, it will be possible to create dew in the stones, and as a result, the problems that we mentioned about dew are more likely to happen.

 Ending speech

As we mentioned, stone is a natural material and may be degraded by various factors. As a result, the type of stone, as well as the type of interior decoration or interior decoration, should be chosen with intelligence to determine the decay of stone later, depending on where the building is being built.
