Strengthening of the brick house with his own hands the foundation

in buildings is often seen carrying a constructive destruction, the problem confronts the owner of a private house the question of how to strengthen the foundations of a brick house with his own hands.

In older homes typically used strip footing with a poor performance.

Belt constructive strongly absorbs moisture freezes and thus crack, causing deformation of the houses.Therefore, the option of strengthening "just put formwork and fill with cement" - this is not an option.

Depending on the depth of damage to the foundation of the house of bricks, of its kind, it is better to choose one of the modern methods of renovation, which will allow you a long time to enjoy your home.

And given below tips will help orient - whether to hire workers for the repair team, or all of the work you can do with your hands.

Causes destruction

Deformation and subsidence of the foundation of houses can be caused by a number of factors, we consider them in detail:

• gravity.Very often the reason why the destruction occurs in brick houses that due to the large weight of the structure;
• design errors.In preparation for the construction of your holiday home, order the project in specialized institutions.Properly executed project - a guarantee of safety of your money, health, life;
• Earthworks.The construction in the neighborhood of other buildings, additions to the main structure of the device will have a negative impact on the constructive;
• Natural factors - soil erosive processes, the level of change (rise) of groundwater, seasonal frost heave, the seismic action;
• Remodelling home.Design of the foundation, its calculation is performed for a specific house with a specific weight, location of structural elements, so ill-considered changes may adversely affect the integrity of the house;
• Disturbances in the operation.This includes cleaning the rain and melt water at home, domestic waste water;
• Vibration effects from nearby highways or industrial buildings, explosions in the quarrying of minerals, etc.

to strengthen the foundation works are scheduled to work at the brick house operation.

The system utilities such work necessarily take place every few years, and twice a year (for seasonal inspections of residential buildings) performed assessment of the foundation.

Signs of destruction and assessment of the state of the foundation

signals for alarm when viewed from the private foundation of the house will cause cracks and hollows.
assess the state of the foundation can be, as they say, with their own hands.

All detected cracks, regardless of the alleged reasons for their occurrence, you need to install "beacons".

This term is called the paper, adhesive strips, are fixed across the identified defects.In complicated form cracks "beacon" placed on each straight section.

degree of danger of destruction is determined by tearing strips of paper under the supervision of them within 10 days.

If during this period of "beacons" remained intact, then perform current repair - driven into fissure scrap bricks and cement, put formwork and make pouring concrete.

Otherwise, it is evident that the destruction of constructive process continues, and therefore, it is necessary to strengthen the old foundation.

ways to strengthen

repair foundation and brick and wooden houses can be made as your own hands, and with the help of hired experts.

Note that the simplest operation at strengthening the base of the tape or pile (columnar) types, but the reconstruction of concrete and reinforced concrete foundations, usually requires the use of special equipment and special skills and knowledge.

course, can be done in the old way - to put the formwork and pour concrete for a few years to forget about this problem, but it is better to get acquainted with the proposed options below, which will tell you how to strengthen the foundation.

Gunning

This method is applicable, if the house is put on the conveyor, brick or rubble foundation, and do damage to the base substrate only require recovery of the outer layer.

Gunning perfectly strengthens home base, increasing its water resistance.When using torkretobetona not need to install the formwork, as well as reducing the consumption of concrete.

Before work is required to prepare a trench around the perimeter of the basement in width from 1 to 2 m and a clear base of debris.

then applied on the foundation notches that increase the adhesion of the concrete to the base solution.

To strengthen the restoration layer is also advisable to use a reinforcing mesh of reinforcement or binding wire.

The video expert shows us how an application on the concrete surface with a concrete gun.

broadening sole

This system is strengthening the foundation of brick houses used for a long time in cases where the damage is quite deep, and it is easy to carry by hand.

repairs Schematic representation of the options we are shown in the figure.

to start taking out the soil on either side of the foundation.Since the inner and outer sides of the special teams are placed low tides, which are pulled together in the bottom of the through-anchor.

concrete (mortar) is poured on both sides between the base and flow in the upper part you can mount ebbs to the foundation with the help of fittings.

remaining period of the trench covered with soil that is thoroughly compacted.

difference from the method when the foundation for broadening put the formwork is to use a damp-proof material for the tide and create additional ties between them.

Installing protective brick walls

Another method available for the implementation of their own hands.

As in previous versions, the preparatory phase is the excavation of a trench (depth of about 1 m) and clean the surface of the base of the debris.

Then all the defects of the foundation are sealed with cement mortar, which is outside the closed waterproofing materials (often with roofing material), which is arranged on top of brickwork (shirt).

Preparatory trench is filled after the completion of a fat clay.

As a method of how to strengthen the foundation, you can use a variety of the above method.The use of reinforced concrete

shirt perfectly strengthens the pier foundation.

amplified around here supports pre-assembled mesh reinforcement, to which is attached a wooden formwork, the distance between the foundation and poured concrete formwork.

get a result construction not only reconstructs the base of the structure, but also increases the bearing capacity of the support.

Pile method

Pile method has proven itself in the repair of both brick and wooden structure with a base of any kind.

There is only one limitation - this method is unacceptable for wooden houses, whose decayed lower crowns.

This method is presented in two ways.

first option is used if the belt, columnar, or some other base slightly damaged.

Special drill holes are drilled through the foundation to be in the ground, in a well placed reinforcement rods, and free space in small portions slowly poured concrete.

This method requires the use of specialized equipment and enough time to create metallobetonnyh rods.

second option - the pile-screw - can be employed both for the strengthening of the foundation, and for its full replacement, which is especially important, for example, for a country house, arranged on the basis of the rubble with minor penetration.

As demonstrated in the video by collaring the soil to a depth in excess of the local level of soil freezing, set-treated anti-corrosion composition pipe piles.

name of this method is derived from designs used in piles, at the end of which the screw blade accommodated.

After installing piles (small houses enough of them one at each corner) of the upper part of the crop, aligning on the level.

also want to note that this option is much cheaper and more economical than the traditional time for the Russian method, when put around the foundation formwork and pour concrete.

As you know, the pile method is available only to a specialized team, with their own hands, this method of strengthening the foundation can not be realized.

general, in addressing the question, "How to strengthen the foundation" - professional advice plus will not be exact.
