How to build a foundation foundation yourself
The construction of the strip foundation has its ownfeatures. The basics of filling are fairly simple. At the initial stage, the necessary calculations are carried out on the thickness and depth of foundation laying, and only then proceed to the main preparatory work and the direct installation of the formwork and reinforcement framework.
You will need
- - Tes;
- - crushed stone;
- - sand;
- - gravel;
- - fittings;
- - wire for knitting;
- - cement.

The level of load on the future foundation isThe main secret, which is necessarily taken into account. All calculations are to ensure that the foundation was powerful enough, but the amount of final construction did not increase to the maximum. And the lack of capacity of the base will lead to the rapid destruction of the erected building, so you should contact the design specialists for assistance in making calculations or use special formulas.
2
The level of soil freezing in your region andDepth of groundwater - the main parameters for the direct determination of the depth of the foundation. Your foundation must be laid in such a way that it is not flooded with groundwater and at the same time, so that the concrete does not collapse during freezing.

Basic preparation for the construction of the foundationconsists in a number of works. First, draw the markings, dig a hole under the excavation, strengthen the inner layer of the soil, install the formwork, mount the reinforcing cage. Pouring is the final stage of the entire preparatory process.

Formwork should be installed taking into account the fact that it will have to be removed after the foundation is poured. Now on sale there are elements of a removable formwork. Also they can be taken for short-term rent.

Remember, the reinforcement cage is an important elementfoundation. It is mounted inside the installed formwork taking into account the load bearing. Direct mounting is performed by welding, and bonding with a special binding wire.
6
When directly pouring the foundationConsider, the quality of concrete must meet certain standards. For heavy construction, 400 cement and fine gravel of fine fraction are suitable.

The time of complete congelation of the solution corresponds28 days. Through this period, you can begin direct construction. But right after installation of the ribbon foundation it is necessary to take care of laying the plinth. Then wait for the specified time and start building the walls.
