On how to properly fill the foundation of the house: the main points

A solid foundation of construction is a guarantee that it will be able to stand for several decades. But how correctly to pour the foundation under the house, so that he could serve that much time? First of all, you need to know that the foundation of the building should distribute as much as possible evenly on the ground the load it receives from the building itself.

To this end, the builders created dozens of varieties of the foundation, each of which ideally meets the requirements of a specific locality. Thus, the choice of a particular type should be carried out, focusing not on your preferences, but on practical necessity.

The most common and universal is the ribbon foundation, about pouring of which we'll talk. To begin with, it is he who makes it possible to organize a basement effortlessly, which is important not only from the point of view of preserving supplies, but also in terms of the thermal insulation of the building. Before correctly pouring the foundation under the house, be sure to conduct geodetic surveys to determine the quality of the soil, its type and the depth of freezing.

First of all, you need to make the right markup. This stage is extremely important, because in the future, those shortcomings that have been admitted here, to fix is extremely difficult, and often completely impossible. Paying for mistakes is a crooked structure. The most important stage, which includes the calculation of the foundation under the house, is the digging of the excavation pit under the pouring. It is very important not to be greedy and make it deep enough. So, for an average-sized cottage enough depth of 0.4 m.

Important! Before correctly pouring the foundation under the house, do not forget to make a pillow! By this concept in this case is meant a layer of sand about 15 cm thick, located at the bottom of the trench. It is better to take coarse-grained, preferably from the river. If this is not the case, you can use high-quality gravel or small gravel, and the thickness of this layer is exactly half the layer of sand.

Next, we build the formwork and put the reinforcement. Note that its rods are unacceptable to weld: the metal in the weld zone weakens and becomes thinner, becoming more susceptible to mechanical influences. Thus, the steel frame is assembled only on the wire, using a special machine for this purpose or manually. In addition, if you are using to build a foundation for pouring nails or screws, assemble it so that the hats remain inside the structure. Before you make a foundation under the house, once again check the correctness of the manufacture of concrete and make sure of its quality.

The pouring itself takes place in several stages. Experts advise to conduct it in layers of 0.2 m, and each such layer should be exactly the same throughout. Pay attention to the armature: it must completely disappear in the concrete, no exceptions are unacceptable here. The fact is that the open bars quickly begin to undergo corrosion, which will gradually go deep into the very foundation of the house, eventually leading to its destruction. After pouring, pierce concrete in several places with a stick: so you create conditions for the escape of excess air. The topmost layer should be carefully smoothed using a trowel or other tools.
