Can I fill the foundation in the winter. How to properly fill the foundation with your own hands in winter

The foundation of the foundation in winter is a laborious and troublesome task, but feasible. It is believed that the time from April to November is the most favorable period for mounting the base of any structure. But there are situations when the work falls on the winter. Thanks to modern building technologies, it is possible to build a reliable foundation that will not yield to the base laid in the warm season by its characteristics. From this article you can find out what the foundation is in the winter, whether it can be poured and how to make such a foundation.

When is winter pouring the foundation necessary?

With the careful observance of all the rules of construction, the erection of a strong foundation is entirely feasible even with the strongest frosts and, as a consequence, frozen soil. Filling the foundation in winter is not always required, it all depends on the project. Most often, the decision to begin construction in the cold period is associated with the characteristics of the soil. There are such areas where the soil crumbles in the summer, and only in winter, when the earth is well frozen, you can dig a good foundation pit. In this case, the installation of the foundation is an excellent solution in the implementation of the task. In many regions of Russia, winter is the main season of the year, and there is practically no summer. Therefore, to erect the foundation of another period simply does not happen. In addition, it is believed that the cost of material and work in the winter is much lower than in the summer months, although serious savings are unlikely to be expected. Sometimes foundation pouring in the winter is necessary, when it is necessary to complete the construction process as soon as possible.

Types of foundations in winter

To arrange the foundation of any structure in the winter, there are several types of foundations. Let's consider them in more detail:

1. The most common among developers - a strip foundation. In this case, experts advise to reduce the so-called "wet" operations, for example, to use ready-made concrete blocks for laying them in a pit.

2. Base of concrete piles. This type of foundation is ideal for light buildings, in particular wooden houses. Observing the construction technology and adhering to the basic rules, you can get a solid pile foundation, not inferior in quality to other types. Further from the article you can learn everything about pouring the foundation in the winter.

How to fill a foundation with piles? First of all, one must distinguish between their types. Piles made of concrete can be bored and drilled. The foundation of screw piles is ideal for winter work. Suitable for any complex soil.

Preparation of concrete mix

When settling the foundation, the question often arises: "Is it possible to fill the foundation in winter using ordinary concrete?" No you can not. For these purposes, one is suitable, which includes special modifiers. Thanks to additives, concrete has time to gain the necessary qualities, it does not grasp prematurely. In addition, modifying additives make it much easier to pour a concrete solution into the formwork.

When choosing modifiers, you should pay attention to the indicators of frost resistance and the rate of solidification of concrete. The required amount of the substance is determined on the scale indicated on the package.

How to apply modifiers?

When using modified additives, it is necessary to focus on some of the main points:

- The use of frost-resistant substances allows to reduce the amount of consumable water by 10-15% in the manufacture of concrete solution.

- The minimum temperature at which the use of modifiers is acceptable is 25 degrees below zero.

- When the humidity reaches 60%, the use of additives is prohibited.

- It is necessary to take into account such factors, in which individual components of the modifiers interact with certain metals.

- The use of additives does not cancel some additional measures for the construction of the foundation in the cold period. When the air temperature is low, some additives that affect the frost resistance of concrete are not enough. It is necessary to heat the concrete, equip additional insulation to maintain a certain temperature of the finished structure.

Use of additional funds that make it possible to fill the foundation in winter

The next method, in which the answer to the question of whether it is possible to fill the foundation in the winter, will be positive, is to ensure the warming of the base. It is known that concrete picks up its highest strength for the first two days. It is during this period that the foundation is particularly in need of protection from low temperatures. To heat the base around the perimeter is used special equipment - a thermal gun. With its help, the temperature necessary for solidification of the concrete solution is provided and maintained. The more the foundation, the higher the power of the device

Also, the foundation can be heated by an electric current. This method allows to maintain the temperature necessary for solidification by means of heat transfer (from hot to cool). The concrete is heated by the bars of the armature, to which the electric current is connected (380 V).

Negative moments of foundation pouring in winter

So, the answer to the question "is it possible to fill the foundation with the winter" is obvious. However, despite many positive arguments in favor of this process, there are some negative points:

- Although the savings in the cost of building materials are evident, at the same time, the price of excavation in frosty weather is greatly increasing. Also, you will incur additional expenses for heating concrete mixes, structures, therefore, in general, the savings in construction in the winter is very doubtful.

- The efficiency of work in the winter is much lower than in the summer, since working in frost is much more difficult.

- The price of additives and modifying substances that affect the properties of concrete is low, but a lot is required to erect even a small basement. And so the price for building materials is significantly increasing.

- Sometimes it is necessary to use special equipment, in particular for digging a pit.

Therefore, before you think about whether you can fill the foundation in the winter, you need to calculate all the costs and consider all the pros and cons of this venture.

List of basic materials and tools for creating a foundation

The following materials and tools are needed for building and pouring the foundation:

• shovel;
• sawdust;
• Building level ;
• hacksaw;
• Master OK;
• Cement and concrete solutions;
• Modifying additives;
• Heat insulation;
• Reinforcing mesh;
• Rubble.

How to properly fill the foundation in winter?

Is it possible And is it worth it? These questions often disturb newcomers in construction. After all, any work in the cold is very difficult, it can prevent snow and frost. The advice of specialists will tell you how to properly fill the foundation with your own hands in winter. The work rules are as follows:

- First of all, a trench or pit is digging, while ground moisture is controlled, which will be collected at the bottom. The water freezes at minus temperature, ice is formed, which must be removed, since nothing can be placed on such a base.

- Next, mix concrete with the necessary modifiers and warm the mixture to the desired temperature.

- The next step is to install the formwork and the frame from the reinforcement. The formwork is poured with a concrete mixture. The necessary plus temperature should be maintained for a certain period of time (to accelerate the process of adhesion) with the help of heating equipment. Immediately after pouring the foundation can be warmed with a ruberoid, polyethylene film. From above you can sprinkle a layer of sawdust (20-30 cm). As a result, we have a ready foundation in the winter.

Can I pour for the winter? The answer is yes. But it is recommended to erect walls on such grounds at plus temperatures, since concrete solution needs some time to acquire strength. Having prepared the foundation in winter (taking into account all the rules and nuances), you can get a solid and durable structure.
