Monolithic base plate with own hands
Every builder knows that it is impossible to achievelong service and the reliability of the building in case of non-compliance with the technological process during its erection. A good house starts with a quality foundation. Its type depends on the chosen project, the features of the ground and the availability of cash from the builder. In private construction, a belt or pile foundation is usually used. Plate, made of concrete and reinforcing mesh, in most cases can be the most suitable option.
Wishing to save as much money as possible, the privatethe developer tries to do all the work himself. But the slightest mistake in the calculations can lead to a serious problem. Often we see houses whose walls are skewed or covered with cracks. This suggests that the calculation of the pressure of the walls on the base is made incorrectly, or the structure is located on the topsoil and stands on a heavily buried foundation. How not to make a mistake and build a house that does not have to be constantly repaired? Very simple.
If on the site chosen for construction,close to the surface of the ground water, then do not make a strip foundation. A monolithic slab will allow you not only to protect the walls from cracks due to soil freezing, but also to save on the construction of rough floors.
Let's look at the advantages that the base plate has.
- The possibility of erecting a house on any type of soil.
- Low construction cost.
- Simplicity of performance of works with which even unskilled builders can cope.
- Load from the walls and floors of the house evenlyis distributed over the entire surface, which means that only 30-40 centimeters of concrete are sufficient to support a two-storey cottage with a base plate. Even for the construction of the Ostankino tower it was required to make a monolith one meter thick.
It is enough to consider manufacturing technologysuch a universal base, as the foundation plate, to cope with each stage. To work will require rubble, sand, formwork, metal fittings and concrete.
First, we determine the position of the future house. We measure the area, denoting its boundaries with the help of several pegs and twine. After that, we remove the soil to a depth of about 30 centimeters. The bottom of the foundation pit is lined with geotextile. This measure will save the pillow under the foundation and will not allow the sand to seep into the ground. We fall asleep a layer of rubble and a rammer. Top with sand. Each layer of a height of ten centimeters is moistened with water and thoroughly weed. We make such a sandwich, until we rise to the level of the rest of the ground.
The finished sand cushion is covered with a layerwaterproofing. It must extend beyond the future foundation by 40 centimeters on each side. All the bands are carefully glued together, turning them into a single sheet. We lay a layer of polystyrene, which serves as a heater. Only after this we collect the formwork. The main preparatory work is finished.
No less important stage is the manufacture of metalfittings. The grid should be located at a height of 10-15 cm from the thermal insulation material. Depending on the thickness of the selected foundation, at least two layers of reinforcement are required. Peculiar legs can be made from pieces of rod. We bind the reinforcement with a special wire or connect it by welding. When this stage of work is completed, it is necessary to once again check the integrity of the formwork.
Now you can order a car with a ready solutionconcrete. This service will be provided by any concrete plant located near the construction. You should take care of the good driveways for the mixer with the solution.
Filling of the formwork must begin with the verydistance angle, evenly distributing the mass of concrete and filling the entire space between the reinforcement. For better work performance, you need to use a vibrator. It will help to avoid the formation of voids inside the solution. Concrete is poured flush with the prepared formwork. After that, the walls of the formwork are laid boards, on which the foundation-plate is leveled manually.
Many beginner builders think that on thisall works are finished. But this is not so. It takes about 20-30 days to completely solidify the solution. But this does not mean that after pouring concrete you can safely forget about the construction for a whole month. Only proper care will provide an ideal foundation. The cooker with its own hands is regularly wetted, sheltered in hot weather and slightly opened for a short period of time in the rain. A little patience, and you can start building the walls of your house.
