Advantages and technology for making a brick foundation

Despite the fact that the most common type of foundation remains concrete, the brick foundation also has a certain branch of application. Most often, this type of foundation is used in the construction of small cottages or one -story houses.

In relation to other foundations, the shape of a brick foundation can be any. So, for example, a formwork that limits its shape is used to arrange a concrete foundation.

In addition, the foundation, even if it sags, is evenly, therefore the duration of its operation is higher. There are no cracks and chips in it, moisture does not get inside, which is inclined to destroy the concrete foundation.

The monolith is highly rigid, in contrast to the brick, which is quite flexible, so it easily withstands heavy loads. In addition, the brick foundation is suitable even for soil with a high moisture level. If there are still certain damages on the foundation, then for its repair, it is enough to replace damaged areas, while the monolithic type of foundation is harder to restore.

The technological features of the installation of a brick foundation suggest the absence of expensive special equipment, when performing work. In addition, in order to build a brick foundation, one person is enough.

If we consider the shortcomings of the foundation of brick, then in this case, we note only the high quality of the products used. That is, the brick that is used when arranging the foundation should have good operational characteristics, only in this case, the foundation will last a long time. The best option is the use of monolithic ceramic brick with red. It is possible to use both single and thickened material, it is such brick that has high resistance to mechanical damage and low moisture absorption.

Please note that the cost of such material is much higher than alternative fakes. We recommend that you give preference to bricks that have well -established building materials manufacturers. The installation of cheap and low -quality material will lead to the destruction of the foundation and the appearance of moisture in the house. In addition, it is important to correctly perform calculations of the number of bricks for laying the foundation. If the amount of material is accurate, then the costs of its acquisition will significantly decrease.

The technology of manufacturing a brick foundation depends on the type of foundation selected for the construction of the house. Two options for a brick foundation are distinguished:

• strip;
• columnar.

Depending on this or that option, the foundation is the pit and the base is prepared for styling. Mandatory waterproofing work is performed. In addition, a drainage system should be installed, which consists of a layer of sand and gravel. In this case, all moisture from the foundation will be diverted underground. The quality of the future foundation and the service life of the house itself depends on the preparation of the base.

Next, a concrete pillow is poured into the pit, the thickness of which is determined by the individual characteristics of the building. After that, it is necessary to wait 3-4 days in order for the concrete to gain strength.

The most common brick laying schemes are combinations one to one and a half, two to two, two to two and a half. Thus, the design is as rigid as possible.

A very important factor is the quality of the solution with which masonry is carried out. It is the cement that makes the design as strong as possible. Although, if necessary, additives, hydrophobic in nature, are added to the composition.

In order for the operational properties of the foundation to be at the proper level, we recommend using reinforcement or a special grid, the use of this material will significantly increase the flexibility of the structure and its opposition to the load from the weight of the house.

Features of strengthening the foundation of a brick house

Before moving on to the direct restoration of the foundation, we propose to consider the reasons why it is destroyed. First of all, this is high pressure at home. This reason is determined by incorrect calculations of the depth of the foundation, thus, an impressive weight of the house, gradually destroys the base, leading to moisture entering it.

Such an option is also possible that during the operation of the house, it was rebuilt or completed, while the number of rooms and the building increased, and the foundation remained the same. The gradual lowering of the foundation is a natural process, which sooner or later occurs for any home.

Incorrect calculations, especially, in the event that the house was built by non -professionals, leads not only to the subsidence or destruction of the foundation, but also to the deformation of the house itself.

In addition, a violation of the construction of the foundation is also a good reason for its destruction. If an insufficiently strong solution was used, additives that improve the adhesion of bricks with each other were not used. Incorrectly equipped waterproofing or the absence of a drainage system, also reduce the duration of the operation of a brick foundation and lead to its destruction.

Environmental factors, such as soil starting, too high groundwater level that risen sharply to the surface, also tend to destroy the foundation. Therefore, if possible, do not allow the destruction of the foundation, all of the above reasons. Particularly careful should be to redevelop or restructure the house, in this case, the proper strengthening of the foundation should be ensured in advance.

We suggest considering several ways by which a brick foundation is strengthened. The first involves the arrangement of a new foundation, on top of the old one, the second implies - the implementation of additional reinforcement, and the third is based on the installation of pile systems.

The use of the first method is relevant if it is possible to lay a new foundation on the sides of the old. At the same time, you will need the presence of a special reinforced frame, which will serve as an additional base that can withstand the load.

This frame is installed on a concrete pillow, which is equipped near the old foundation. For the manufacture of the frame, purchase reinforcement, which is first welded into the shape of the grate. At the same time, the cells have a square shape, the size of which is 0.2x0.2 m.

Important: it is forbidden to change the size of cells for the manufacture of a reinforcing frame. Specialists have proved that this rule does not adhere to the occurrence of problems with the distribution of the load.

It is possible to make a frame from a special wire, in which case a special knitting machine will be required. However, the reinforcement, not the wire, remains the higher quality, reliability and strength of the foundation.

After the manufacture of the frame, the corner sections of the foundation are exposed, while the depth of exposure is about one meter.

The reinforcement is lowered into the pit and poured with a concrete solution of high quality. Next, the base is tamping.

In addition, it is possible to strengthen a brick foundation with your own hands using complete reinforcement. In this case, the reinforced frame is installed not only at the corners of the foundation, but also in its perimeter. This method is relevant for the foundation that has a high degree of destruction. First of all, the entire foundation is divided into many segments, the length of each of which is up to two meters. At the same time, in each of the sections, a small recess is dug up, the width of which is up to 50 cm.

Next, holes are drilled on the surface of the old foundation, it is to them that reinforcement or steel rod is attached. The length of the reinforcing bar is about 35 cm. Next, pre -made frames from reinforcement are laid into previously dug trenches. Thus, the foundation is strengthened around the entire perimeter. Each of the trenches is poured with concrete solution. However, keep in mind that the work is carried out gradually, after installing the reinforcement in one recess, it is poured with a solution, then it should be waited a few days until the solution acquires strength. The restoration of the foundation with this takes more than two weeks. It is preferable if work is carried out in the summer. In addition, the optimum temperature for work is from 10 to 25 degrees of heat. Otherwise, there is a risk of damage to the finished strengthening structure.

The third option for strengthening the brick foundation is based on the use of piles of a brown -defensive type. This method is rarely used due to its high cost. However, it is considered one of the most modern and productive methods of restoration of the foundation. In order to perform work, perform a number of actions:

1. First, double -sided drilling of the old foundation is produced until the moment is found on it, hard soil is found.

2. Keep in mind that the wells are installed at a certain angle. It is preferable to entrust this process to professionals.

3. The size of each well in the diameter is about 23-25 \u200b\u200bcm. The drilling depth is determined by the individual characteristics of the building and soil.

4. In the well, which turned out, they fill the cement mortar. Next, its frame part is installed, made of reinforcing bars.

5. However, the installation of the frame is carried out only after the final hardening of the concrete solution.

As a result, a reliable frame is obtained, which supports the brick foundation from all sides, taking part of its load on itself. The number of piles that are installed on the foundation is determined by the degree of its destruction and the type of soil, which is characteristic of a given area.

Among the shortcomings of this restoration method, first of all, its high cost and the need for special equipment, with which drilling is carried out, is noted. In addition, bored piles also need to ensure the proper level of waterproofing, which will protect them from destruction of moisture.

Keep in mind that the most important rule of the long -term restoration of the foundation is the timely elimination of its small structural changes. Otherwise, there may be negative consequences that will require the construction of a new foundation and at home.

Periodic check of the quality of the foundation, the lack of cracks on it will help save the house in safety. The foundation is the basis on which the entire building is based.

Strengthening the brick foundation price and technology for performing work

The cost of work on the restoration of a brick foundation depends on the type and method of restoring the base of the house. In addition, each of the methods by which work is performed is based on the use of additional materials, such as piles, concrete, reinforcement, special equipment, etc. Therefore, if necessary, specializing in this stage of construction work, companies calculate the cost of work individually for each building.

Using this method, it will be possible to independently determine the need to restore the foundation. Since after several years from the moment the building is erected, it gives a certain shrinkage. As a result, on the foundation, in some cases, cracks appear. Some of the cracks is enough to disguise with cosmetic repairs, while others, over time, expand and pass moisture into the foundation and at home, they need better restoration. Since the increase in cracks is due to the fact that the load on the foundation is too high. In this case, strengthening the foundation will help to avoid its destruction.

In order to determine the changes in the crack, a patch of paper or gypsum should be glued on it. If after a week from the moment it is gluing, the integrity of the patch will be broken, then the crack progresses. In this case, you need to strengthen the structure.

In order to strengthen the brick foundation, the presence of:

• special beacons;
• shovels;
• steel pipe;
• concrete solution;
• wooden boards.

After the destruction of the lighthouses, you should immediately dig a hole with a slope of 40 degrees near the foundation. The depth of the pit depends on the depth of the foundation. An asbestos-cement pipe is installed in the foundation with a diameter of up to 20 centimeters, and they will contribute to its strengthening.

Next, work on pipe filling is carried out. At the same time, work is performed three times, with an interval of 1-2 days. After that, it is necessary to put the lighthouse on the crack again, if it does not break, then the problem is eliminated. Otherwise, we recommend contacting specialists.
