Strengthening the foundation of the house is an additional method that allows you to eliminate a variety of defects that appear during the operation of the structure.

Factors contributing to the destruction of the foundation of the building:

• vibration actions of internal and external nature;
• increase in load due to improper use of the structure;
• The ongoing construction work nearby;
• change soil properties (swelling, swelling, occurrence of an increase in water level, excessive hydration);
• incorrect foundations laid at home;
• an error in the drafting of documents, etc.

Strengthening the foundations of the old

The process of destruction of the base may begin as by increasing the pressure on it, and on old buildings. Therefore, the repair and strengthening of the foundation should be carried out taking into account all building technologies, so as not to fill up the building and not to suffer the most.

Ways to strengthen the foundation of the belt type, there are quite a few, but the offer to divide them into two main groups:

1. Strengthening the foundation for building

Installation and strengthening of the strip foundation is carried out by using the following techniques aimed at strengthening and reconstruction of existing facilities:

• Restoration of the base;
• Increased area of \u200b\u200bthe foundation;
• Adding piles to enhance the design.

If the foundation has not very large cracks, then its initial structure should be restored. If the foundation of the house is destroyed and new floors are erected, then it is necessary to increase its base. All this can be done with a shirt made of reinforced concrete, which surrounds it. This method is used if it is necessary to partially enhance the ribbon foundation.

Also, the gain can be performed using the foundation plate installed directly under the house. Sometimes such a stove is used to replace the old base. After that, the foundation served his service should be sealed from reinforced concrete. This strengthening does not imply the help of specialists, since everything can be done independently.

2. Strengthening foundations for drilling and w / w pile (are used to strengthen a column foundation)

Foundation Strengthening Technology:

• to make the installation of the pile elements of the drowing view, initially need to drill the holes of a certain diameter and only then start drilling well under the pile;
• next, there are frameworks created from a large number of reinforcing products;
• then the fill with concrete composition for injection technology.

This method involves the submission of concrete in small portions.

In about the same way, the foundation of the tape type is created:

• first choose the ground around the base, it is thus the sinuses;
• then the cone holes are drilled (all this is created on the slab area);
• then the cavities make pile elements.

After the set of necessary qualities occurs, they are able to take over the load transmitted by the wall structure. Upon completion of all works, the soil falls asleep back.

As for piles from reinforced concrete, they relate to composite products, so they are mounted on the principle of special pressing:

• first, it is necessary to establish "strapping beams" in the area of \u200b\u200bthe strengthened design (they imply monolithic jumpers from reinforced concrete). Step must be observed from 1-1.5 m. The structure includes longitudinal beams;
• upon completion of the work, the pile elements are driven directly into a fixed part of the base and fixed with a tough mixture.

Strengthening the foundation with your own hands

Ways to strengthen the foundation:

1. Expansion of the soles in the process of strengthening the brick foundation

Such technology is considered excellent and proven by the method:

• initially, it is necessary to make the layout of the building on the capture of 200-300 cm long;
• note a certain area, you can start opening the base (it is necessary to comply with the sequence of actions, otherwise there is a probability of driving a soil);
• the surface of the foundation is cleared;
• in advance drilled holes mounted metal pins;
• between the base and brick masonry are metal beams;
• these beams with welding fix longitudinal beams;
• then in the ground that will subsequently take on the basis of the basis for the new foundation, the crushed stone falls asleep;
• further, work is carried out as an ordinary carrier structure.

Thus, a rambling is created, the arrangement of the formwork system, filling with a mixture of concrete and so on.

2. Roots reinforced concrete teams

To enhance the foundations in this way, tides are installed immediately with the compression of the soil. Here we are talking about the soil, which is located at the place where the new foundation will be laid.

Whatever the strengthening method you do not have chosen, be sure to do the work qualitatively and stages:

• first, it is necessary to make a fence of the Earth;
• next, make the installation of combined products on both sides of the laying of the carrier structure;
• connect the elements using anchors-screed and skip them through the base of the structure;
• then you need to enhance the gap between the main structure and the upper base area using concrete rigid mixture and reinforcement;
• then to fall asleep the ground back and compact it.

3. Operation of individual parts

In cases where to strengthen the old foundation is not possible, they produce a replacement of individual elements of the supporting structure:

• the holes are dried where the transverse metal beams with special subdivities are mounted;
• the temporary supports are installed hydraulic jacks.

Thus, the wall is slightly relaxed above the surface, and experts get the opportunity to conduct a normal strengthening.

4. Cement

Stages of work:

• In the base of the house and ground the holes are placed;
• Next, a mixture of concrete under high pressure is supplied.

The composition is qualitatively fills the formed emptiness. At the same time, the influx of the solution is formed, which significantly increase the strength of the carrier system. Thus, wall structures can be protected from premature destruction.

5. Reinforced concrete shirt

It is based on areas with compacted soil masses. The function of this strengthening is reduced to enhance the brick or rubble tape and increase durability certain wall structures (e.g., the basement and the outer wall). For better fixation of the foundation further mounted anchoring elements.

6. The protective wall of bricks

Such a system is able to eliminate the deformation of the supporting structure.

stages:

• It is ground fence (the width of 100 cm);
• portion is cleaned;
• surface is treated with a specific composition;
• after drying foundation isolated or bitumen roofing felt;
• of bricks creates a protective layer (mantle);
• poured into recesses fatty type clay.

Strengthening concrete foundation PX / 80 micro-steel pipes

Technology:

• in foundation reinforcement of concrete are inserted special blocks;
• after casting and partially drying the mixture under pressure introduced into the concrete pipe micro-PX / 80 (this occurs by means of a hydraulic jack which is equipped with a special device for testing and determining the pressure and the stress on each component).

Strengthening pier foundation

Stages of work:

• first you need a special compound to cement all the cracks;
• then externally on reinforcing grid, which is nailed to the old base, concrete skip coat (5-7 cm);
• inside the building, close to the wall, you can nasverlit pile and make a hanging grillage, which reinforcement is connected with the old foundation by means of pillars and zabirok or dig around the outside pillars trench before they bottom, installed against the formwork and pour the liquid composition, and the outside surface of the closed roofing material ;
• then the pit is filled with sand;
• and a warm blind area.
