How to create a ribbon foundation yourself?

When erecting a single-storey or low-altitudebuildings, as well as a garage or a bathhouse before the start of construction work, you can make a ribbon foundation with your own hands, which will become a reliable foundation for bearing walls. This kind of foundation is quite simple, and therefore does not require the use of special calculations during the design, so in this situation it is possible not to be wasted on paying for the services of professional builders.

Definition: By creating a ribbon foundation with your own hands,It is necessary to first study the strata of the soil located on the site of the construction of a future low-rise building. The foundation itself is built on the layers of dense ground and represents the underground part of the structure, which is capable of perceiving loads from the bearing walls, and then transfer them to the base of the structure. Its upper plane, where elevated parts of the structure are erected, is usually called the surface, and the lower part is called the base of the structure.

Raising a shallow ribbon foundationwith their own hands, will have to create a reliable reinforced concrete strip, which runs along the entire perimeter of the structure. Such a tape must be laid under all external and internal walls of the building so that the cross-sectional shape remains the same throughout the perimeter.

Features: As a rule, the ribbon foundation with their own handsis built according to a fairly simple technology. However, for such a foundation of the building is characterized by increased labor intensity, the need to use a crane, as well as a significant consumption of material - a large amount of formwork and a significant amount of concrete. If you create a foundation foundation of blocks, you can save time, because in this situation, the blocks are stacked relatively quickly, and builders do not have to wait until the concrete solution dries well.

Stages: To build a strip foundation with your ownhands, you need to perform preliminary calculations before it is poured. It is recommended to make a simple estimate, which provides for the costs of laying reliable fittings, the purchase of boards for formwork, concrete mortar and the costs of direct construction. If the building is planned to have a warm underground or basement, it is better to use a columnar-ribbon view of the basement, in which individual pillars become an integral part of the construction.

At the first stage, thesoil on the land, where the construction of the facility is underway. If the soil beneath the future building is loose and dry, then the strip foundation becomes the optimal solution for the builder, and it is already possible to proceed to the marking of the site, performed with simple measuring instruments, as well as pegs and ropes.

Further it is necessary according to the breakdowndig a trench under the foundation under construction, which you can dig and shovel, saving on attracting specialized equipment, and avoiding additional money costs. When the trench is ready, and its depth becomes sufficient for laying the foundation, it is already possible to proceed to the following works. First, the trench is filled with sand, and then - with rubble or gravel, with other suitable building materials. The material used to fill it should be densely packed, and the thickness of the filler should not be less than twenty centimeters.

To ensure that the foundation remains stable and durable infor many years, at the time of its erection it is necessary to use reinforcement. After laying the seal, a concrete solution is poured into the formwork, and the thickness of its layer must be at least half a meter. Concrete dries for a week, however, before the erection of load-bearing walls, the foundation must be tested for strength.
