Gummy soils - not a problem with the right approach

For the erection of the foundation, the soils are a specific problem, which involves taking into account the force of impact, mass and assumed load. This primarily applies to clayey, 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, a type of foundation is chosen that can ensure the reliability of the entire structure. Where there is abrasive 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 also allowed to be installed on abrasive soils. However, shallow recesses 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 are not widely used in individual construction, since they involve the use of special equipment.

What actions can be taken if there are cloddy soils on the site? The most radical option is to dig a foundation pit, the depth of which will exceed the freezing level of the earth. Later 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.

Thermal insulation is another method that can positively affect the soils. This is especially true for the construction of light, shallow buildings. Laying on the ground on 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 that is capable of providing a qualitative diversion. Thus, the water from the ground will go to the side, without adversely affecting the soil.
