Why is there a different depth of freezing in Moscow Region?

The depth of freezing of the soil depends directly on its type, climatic conditions of the terrain, humidity and other. Features and parameters are taken into account when drilling wells, construction and other types of economic activities.

What is the depth of seasonal soil freezing? What does this indicator affect?

It is a random variable, and it can not be constant. This is due to the fact that some factors that affect the parameters do not change with time (for example, soil type, relief), while others, on the contrary, change constantly (soil moisture, snow cover height, intensity and duration of reduced temperature, etc.). When building buildings, the depth of ground freezing is of great importance. Today, the Moscow region is actively building. On how deep the soil freezes, the depth of the basement of the structure depends. During construction, it should be borne in mind that in winter (in case of permanent residence) the area under the house warms up. Due to this, the estimated depth to which the soil freezes can be reduced by fifteen to twenty percent. Ensure maximum preservation of soil heat is capable of a strip of high-quality insulation with a width of one and a half to two meters. It is laid around the house, thus creating a heat-isolating blind.

What causes different depths of freezing in Moscow region?

The values range from 50 cm to 1 m 80 cm. This difference is explained by specialists with different soil density. The stronger the frost and the denser the soil, the more the ground freezes. In soil saturated with moisture, the indicators will be higher than in the dry. As such, the average value for the Moscow region is absent. But there is a normative depth of soil freezing. SNiP sets the following design value - 1 meter 40 cm. But it should be said that in its determination, extremely harsh climatic conditions were taken into account: high groundwater level , severe frost, no snow. In reality, the depth of soil freezing in the Moscow region is different from existing standards. Often it does not exceed one meter. If the winter is very cold, there is practically no snow, then the level can be up to one and a half meters. In the west of the Moscow region the soil freezes by about 65 cm, and in the east, in the north, in the southern part - up to 75 cm.

Influence of soil type

The depth of soil freezing in the Moscow region depends on various factors. One of them is the type of soil. Thus, the sandy soil freezes to a greater depth, in comparison with clayey soil. This is due to the fact that the clay is more porous than sand. Sandy soils, loams, coarse-grained soils, peat bogs and sandy loam are characteristic of the Moscow region. The specialists who take into account all the factors in the complex can determine the level as accurately as possible. For example, coarse soil begins to freeze at a temperature of 0 degrees. For sand and sandy loam the depth of freezing is 132 centimeters, and for loamy and clayey soil - 1.2 m.
