After prolonged use at home sometimesthere is a need to change or repair the base. Reconstruction of the foundation - is the conduct of several stages. The need for this work may be required when cracks began to appear on the walls, the building collapsed, and water began to appear in the basement.
The first stage is to analyzehow much the foundation is destroyed, only after it is possible to start lifting the building to the required height. Sometimes it can save only a partial buildup of the base with concrete products or bricks. Their installation is made in those places where parts of the old base have been removed.
If you have to work with a strip foundation,then it will be easiest to partially remove it, replacing it with a new one or strengthening it. Initially, the house will have to be raised using jacks, and this should be done uniformly around the entire perimeter, otherwise the walls can be irreversibly damaged.
If basement renovation involves workwith piles, then, as a rule, they are completely replaced. After the reinforced concrete substrate is filled, you can begin to install new pillars. Work on the reconstruction of any type of foundation must begin with digging a trench around the perimeter of the house. After the foundation should be cleaned of dirt and old finishes. A new base must be made stronger, for which the reinforcement should be applied. Its installation is carried out with some deviation from the wall. The next step is to install the formwork and pour the solution. In this state, the new base must be left until the concrete hardens. Only then can the formwork elements be removed and backfilled.
Reconstruction of the basement of a wooden house, asusually accompanied by the replacement or repair of the lower crown. Initially, a baseline survey will be conducted. Waterproofing also needs to be replaced, as the years of operation lead it into a state of disrepair. As a new one, it is preferable to choose a monolithic foundation, for its installation it is necessary to raise the building by about 50 cm. Do not forget about the presence of reinforcement, the optimal diameter of the bars is 10-12 mm.
In order to replace the rims, it is recommendedapply parallel bars. They need to pick up, given that they must be dry and smooth. If the building is installed on a relief surface, then the foundation should be made on the basis of piles.
Foundation renovation should be carried outEspecially carefully at the stage of lifting the house, as the wooden walls can be easily damaged. Jacks should be located in those places where the material has no damage and putrid formations. These areas to be strengthened with metal 5 mm gaskets. They will allow you to evenly distribute the load on the logs. Under the jack should be laid boards, the length of which is 50 cm. The walls before the process of lifting must be strengthened with boards.
Now you can install the formwork and put down the reinforcement. After the concrete racks harden, the house can be lowered by removing the jacks.
Реконструкция фундамента сваями считается the simplest solution to the issue of changing the base of the house. Initially, the design is analyzed for integrity, then you can proceed to the twisting of the piles, placing them perpendicularly relative to each other. The step between them should not exceed 2 m. After installation, it is necessary to tie up the supports with a channel. Then the building is raised with jacks, which allows you to get rid of the old foundation. At the next stage, under the house perpendicular to the lags, it is necessary to make I-beams, which are welded to the channel bar. It is necessary to lay waterproofing on beams. Completion of these works indicates that the house can be put in place. The renovation of the foundation of the house is completed. However, it is worth considering that such work is preferable to produce, with the help of professionals.
