Everyone dreams of their own home. Most decide on the independent construction of a house on the territory already owned. Here it is necessary to take into account the specifics of the location of the site and the climate. In various parts of the country, the depth of soil freezing is very different. Why is this indicator so important?
In winter, the soil freezes due to the presence of
groundwater. They are located at different depths under the soil (depending on the area of residence and climatic conditions). If you lay the foundation of a house higher than necessary, then an indicator such as the depth of freezing of the soil will inevitably play a role in the process of destruction of the house.
It is easy to guess that the lower the temperature drops in the winter season, the greater the depth of freezing of the soil.
It also depends on the
type of soil. The standard level of freezing is given in special documents such as SNiP. It is important to understand here that the numbers indicated in this literature are maximum and are given for the most critical cases. Actual freezing depths will be slightly lower. Each city of the country has its own standard depth of soil freezing.
Frozen soil consists of ice, gas, mineral particles and water. The phenomenon of bloating of the soil, which can occur if the technical requirements are not observed during construction , is very dangerous for the built house. This is due to an increase in soil volume after groundwater freezing.
There are also
soil types that do not thaw in summer. They are called permafrost.
It is necessary to take into account the fact that with permanent residence in a house built, the depth of freezing of the soil in winter decreases by twenty percent. You can also contribute to its reduction by planting shrubs around the perimeter of the structure.
When paving the paths of a summer cottage, it is also worth considering the level of freezing of the soil. It can adversely affect building material and form cracks.
Experienced gardeners know that with the help of greenhouses and greenhouses, you can increase the speed of thawing soil in early spring. This is important for those who need to get an early harvest.
If the house is built on heaving soil, then this will inevitably lead to its destruction. Such soil is highly susceptible to freezing and increases in volume, affecting the foundation of the structure. The value of the bearing capacity of the soil must be known before laying the foundation. The area of the house should be increased in case of a low indicator of strength. It’s unpleasant when you see cracks on the facade of the building. They become the first evidence that the depth of freezing of the soil was not determined correctly even at the stage of laying the foundation. Therefore, to obtain a qualitative result, you need to be patient and take into account all the nuances before the start of construction. Then the built house will remain a strong and reliable refuge for you for many years.
