The foundation is the basis of every residential building. The operational characteristics of the building, its stability, strength and safety depend on its strength and reliability. After all, it is he who takes on the main load from the entire structure, which is why its competent construction is so important.
The strip foundation is affordable and quite popular: the choice often falls on it when building baths, houses and private garages. It is much more economical than its pile counterpart, at the same time it is much more functional.
Strip foundations are the best suited for the construction of dwellings with an actively used basement.
Preparation of the project for the device of the future foundation
First of all: the design and construction organization will have to order a geodetic survey to determine the type of soil, how much it is able to freeze in winter, the presence and depth of groundwater at plot. Also, this company will perform the necessary calculations and draw up a project for the device of the future foundation.
If the planned building is small, you can do all the necessary measures yourself. For the construction of a cottage or other large-scale structure, it is advisable to turn to professionals.
Preparation of materials
Usually high-quality concrete of two hundred grade is used for such works. The mixture can be made independently, or you can order ready-made. The process is quite laborious, which explains the heterogeneity of the base, filled with separate portions.
The composition of concrete for the manufacture of strip base includes:
One of the important steps is marking the site for the foundation.
First, the site is freed from foreign objects and small debris. Further, all the soil from the site is cut to about 15 cm depth to further limit the processes of decay in the basement of the building.
How to markup?
Pegs are installed there too.
Temporary supports should be made to prevent soil shattering!
Use a rope to mark the contour for the formwork.
Install supports at the corners. This requires bars with a thickness of 5 centimeters.
The formwork is made from edged boards, which are connected using corners with self-tapping screws or wooden blocks.
Corners and bars are located outside the formwork, the caps of the screws remain inside.
To avoid deformation of the structure when pouring the cement mass, props are placed outside.
The formwork must rise above the ground to such a height that the resulting foundation is at least 30 cm. The level to which the concrete is poured is marked inside the foundation.
Welding violates the corrosion resistance of the material in the places of its impact, therefore it is not recommended to use it!
If concrete is ordered, then pouring is carried out at one time, at once. Layer-by-layer filling is done if the mass is prepared on its own.
Step-by-step pouring of the strip foundation
Mix well so that all the crushed stone is evenly moistened.
Only after the final maturation of the concrete monolith can you proceed to further construction and start building walls.
When the formwork is removed, it is necessary to perform a high-quality waterproofing of the base.
This will improve the moisture-insulating and heat-preserving functions of the strip foundation, as well as increase its service life.
