Lifting the house on screw piles: features of the work

If you decide to lift the house on screw piles, then the complexity of the work can affect some factors, among them it should be noted:

• The presence of a fireplace or stove;
• Terrain relief;
• Deviation of communications.

At the first stage, marking is carried out, then the piles are twisted along the perimeter of the building and the house is hoisted. The next step is to install the headers.

Markup and elevation

Due to the fact that the screw piles after the construction of the house is no longer possible to install under the building, their screwing should be carried out around the perimeter, having retreated from the old base about 50 cm. This value sometimes decreases to 40 cm. Quite often, On screw piles. To replace the base, the building is raised.

For this, hydraulic or screw jacks are used. Depending on the weight of the construction, under the supporting beams jacks are built in the amount of up to 10 pieces. The minimum number is 4 pieces. Each side of the house comes off with the help of levers from the old foundation and rises only 5 cm. Under the joists are laid boards, which have the appropriate thickness. Lifting the house on the screw piles provides work with the walls alternately. At the final stage, the house is raised to the calculated height.

Installation of I-beam and heads

Once the house is at the required height, you can cut the screw piles, given the level. Pipes are filled, usually concrete is used for this. On their surface are mounted headers. Under construction, I-beams are being built. The whole construction is scalded.

Lifting the house on screw piles necessarily involves applying primer to the welding places. After the completion of the work, the old foundation can be removed, while the building itself can be lowered onto logs made of I-beams.

Why you should choose screw piles for lifting

It is important to read the tips before starting work. The rise of the house on screw piles, according to experts, has many advantages. Among others, it is necessary to highlight the reduction in the timing of manipulation compared to other methods of recovery. In addition, such work is usually carried out in just a few days. True, sometimes the rise is stretched for 2 weeks - everything will depend on the mass of the structure and its area.

This technology has some drawbacks, one of them is expressed in the fact that the method is suitable only for raising light houses, this is especially true for timber and wooden houses. In order to solve this problem with multi-storey and stone buildings, other technological solutions are used.

Cost of work

Raising the house on screw piles in St. Petersburg will cost 150,000 rubles if the building has dimensions equal to 6x9 m. If the house size is reduced to 6x5 m, the consumer will be able to save, because to pay for the work will have 110,000 rubles.

The rise of houses on screw piles in Yaroslavl will cost a little less - in 100 000 rubles. In this case we are talking about the construction, the dimensions of which are 6x6 m.

Process tricks

It is important that the jacks in the process of lifting be able to undergo a load from the house. You can provide this possibility if you know in advance the density of the material at the base of the walls and the dimensions of the building. To make the building easier, it is necessary to take out furniture from it. Even the weight of household utensils in the sum turns out to be quite substantial. All extensions before starting work are disconnected from the house or dismantled, because otherwise they can prevent lifting. Among such structures it is necessary to allocate:

• Veranda;
• porch;
• lumber room.

Conclusion

If the foundation is out of order, cracked and began to break down, this indicates that it's time to replace it. Quite often as an alternative solution are pile foundation, which is quite cheap and installed in a short time. The distance between piles should be equal to 1.5 m.

The depth of their laying is usually greater in comparison with the average freezing level of the soil. If this recommendation is neglected, then the foundation in the process of exploitation will only repeat the fate of the old ground. Its elements will be influenced by the strength of the bundle in winter. The most difficult stages of the process are the preparation and lifting of the building. As for the repair of the building itself, sometimes such work takes only one day, which is true, if the work is done by specialists.
