For the erection of a foundation of undergrowthare a specific problem, which involves taking into account the force of impact, mass and expected load. This primarily applies to clay, silty and fine-grained earth. In winter, the water in the soil layers freezes and swells, and the process is uneven. In this regard, the sludge of the structure may pose a certain threat, leading to deformations in the bearing structures. In this case, it is very important to properly arrange the foundation. The properties of the soil have a direct impact on it, so they should be taken into account first.
First, the type of foundation that is capable ofensure the reliability of the entire structure. Wherever there is a hectic soil, if a columnar base for a bulky building is chosen, then it is necessary to lay it below the depth of freezing of the soil. For private buildings, this option is not suitable, since the strength of the punching is able to squeeze out the foundation, the load from which is much lower. In private construction, as a rule, unfinished and shallow bases from the columns are made.
As for the ribbon foundation, it is alsoit is permissible to install on abrasive soils. However, shallow depths are allowed to be used only with a depth of freezing of soil not exceeding 1.7 meters. Depending on the soil soils, the type of belt foundation is chosen. On lands with weak mobility, concrete blocks without a rigid connection can be used. However, in the remaining cases, a rigid coupling or monolithic reinforced concrete is required. Structures based on piles have not received wide distribution in individual construction, since they imply the attraction of special equipment.
What actions can be taken ifthere are cloddy soils? The most radical option is to dig a foundation pit, the depth of which will exceed the level of freezing of the earth. In the future, it is filled with tamped sand, acting as an excellent foundation for the foundation. This method can be considered the most reliable, but in this case, the financial costs will be very serious, which is primarily due to the large amount of work.
Another device that can positively influenceon the abyssal soils, is warming. This is especially true for the construction of light, shallow buildings. Laying on the ground along the perimeter of the foundation insulation material, you can avoid freezing of this soil. The width of the heater must correspond to the depth of freezing. As for the thickness of insulation, it is selected individually. You can also try to divert water from the house: if there is not, then there will not be any swelling of the soil. To implement this idea, a drainage system is created which is capable of providing a qualitative diversion. Thus, the water from the ground will go to the side, without adversely affecting the soil.
