How to strengthen the foundation of a private house

Modern technologies and materials allow you to reliably strengthen the foundation of the old building. However, before repairing, it should be determined and eliminated all the factors that led to the destruction of the base. Otherwise, your efforts will be in vain.

For each base, there is a way of strengthening. If you have to work with the foundation of a wooden house, then the construction is raised by jacks and take a new foundation under it. The foundation of the brick house is enhanced by a classic method, with a reinforced concrete shirt or pile.

The classic method implies the creation around the old foundation of the new, building a reliable support to the old. At the corners of the building, throw the holes with a width of 1 × 1 m and the depth below the old foundation for one meter. Pits should bargain the existing basis.

Try in the old foundation of the holes for the reinforcement and the lobbery for the solution. Make an armature frame. To do this, the wire is suitable, which is welded, forming a cell 20x20x20 cm. In the pits, collect a formwork.

Install the frame in the pit. Insert the reinforcement into the made holes of the old foundation and weld to the reinforcement frame. Pour the concrete reinforcement frame and all the performed holes in the existing foundation. Perform work quickly so that the open areas of the foundation as small as possible remained bare. After hardening the concrete, start working with another angle.

In serious cases, create an armature belt around the perimeter of the house. Start work on a plot of length not more than 2 m. The next area do only after the concrete solidification on the first one. Failure to comply with this requirement can lead to a deterioration in the state of the foundation.

Piles to strengthen the foundation are used for large foundation deformations. The method is to install piles around the perimeter of the old basis. There are several types of piles to strengthen the foundation.

With a boronobibilic method on both sides of the base of the house, parallel to the foundation, perform wells with a diameter of 100 to 300 mm, a depth of about two meters, at a distance of 1.5-2 m. The distance from the well to the wall is not more than 2.5 m. Of the wire with a diameter of 10 ... 12 mm make the reinforcement frame and install in well. Fill fittings concrete. Secure piles to home anchor bolts.

If drilling work is impossible to perform, piles are pressed into the ground closer to the deformed foundation. Such piles are metal pipes or profiles with dimensions of 20x20 or 30x30 cm. Paving is carried out by jack. After the expiration of the pipe is completed, fill in concrete and strictly connect with an old foundation with anchor bolts.

Screw the pile - construction in the form of a pipe with a diameter of from 108 to 219 mm with a screw pad. Screw the pile into the soil next to the foundation. After screwing the pile, the platform allows you to transfer part of the load from home to piles.

Ribbon foundations are enhanced by a "reinforced concrete shirt." To do this, beat the foundation to the very foundation. Clean the concrete, cracks in the foundation. Speakers cut. In the foundation, imract the holes and install metal reinforcement in them. Strokes Connect the reinforcement and breed. Make a formwork and fill the frame of concrete.

The most up-to-date method of gain is the method of drilling piles. On both sides of the foundation, under it, the inclined wells with a diameter of 25 cm. The auger must reach the durable soil. In the well, install a metal frame and fill with concrete. After the concrete solidification, the house will hold additional supports in the form of reinforced concrete piles.

Foundation Repair refers to difficult operations. It is advisable to invite an architect that examines the base of the house and will recommend the optimal option.
