Cracks in the foundation how to eliminate

The crack in the foundation is not a sentence. You can still correct if it is reasonable to approach the analysis of the nature of the split and the reasons for its education, which will help you choose the method of restoration of the base. The main thing is the urgent performance of repair work, even if the thickness of the crack - with hairs.

Eliminate such reasons for the formation of cracks in the foundation:

Technological. Often, faults in the foundation appear due to violation of the construction technology of its structure. This is also a poorly fixed formwork, and made by the rules of reinforcement, and small vibration of the solution when laying. The base can crack if the concrete brand is incorrectly selected and the insufficient reinforcement coefficient is calculated. Section may occur if the foundation is laid above the depth of the soil freezing or point, which is a project mark. Do not promise anything good freezing of the surface in the winter.
Structural. This appearance ranks errors of architects at the design stage, when the bearing capacity of the soil and the very base was incorrectly performed, as well as the design depth, on which the foundation is laid, or as a result of the miscalculation. In addition, the projects are often developed without geological surveys of the soil, and subsequently the load on the soil is unevenly distributed, which leads to its service.
Operational. The occurrence of cracks in the foundation is not always associated with the errors of designers or builders, the owners of the construction themselves are often to blame. For example, they decide to increase the floors of the house, forgetting about the strengthening of the foundation. Also provoke the destruction of the foundation can be the effect of water that penetrates the cabin around the house, dampness in the basement, improper performance of surface and deep drainage, external environmental factors.

The splits on the border between the basement and the foundation, as a rule, arise due to the close neighborhood of building materials that have different physical properties and density: brick and reinforced concrete, brick and wood. Especially risks increase when freezing or saturated with moisture materials.

To choose the right method of repairing cracks and resuscitation of the foundation, it is recommended to analyze its appearance, trace the direction of the split and measure its size:

Even if the split has a small size, with hairs, do not ignore it. You may not have time to look back as a small crack will turn into a deep furrow. Especially dangerous cases when convexities and depressions were formed in the foundation, large faults, a width in a finger, or from the edges of the fracture waters.
The statement is not quite true that horizontal cracks do not pose a danger. The reasons for this are linked in the drying of concrete under the influence of low temperatures and high pressure from the damp soil. Thoroughly read the long horizontal faults, if they are accompanied by convexities, the foundation is not excluded or excessive pressure on the carrier wall. Measure the level of crack size, if it is greater than 1 cm or the comb is formed, then get ready for solid repair.
Vertical faults are the worst option, especially if such a crack is expanding up or down. Also, remember that it may be unclear, located underground.

If cracks have small sizes and hair thickness, proceed to repair without waiting for their expansion. For quick resuscitation, you should purchase a special polymer waterproof material, which is called polymer concrete. It contains such elements as epoxy glue, a filler, which is used crushed or gravel, polyester, vinyl ether, sand as a small aggregate. With this mixture, carefully close all the locations of the foundation. For defects, epoxy resin is quite consistent.

With extensive damage to the base of the house, the local works could not do, it is recommended to strengthen the foundation. If the foundation is brick or built from butte stone, injection is used with a cement solution or synthetic resin. Try in the body of the Fondament Shurfs, which have a diameter of 30 mm, withstanding a step of 50 cm. Remember that the shurn depth should be 0.5 width of the foundation. Immerse the injection in the prepared wells in the prepared wells in which the enhancing chemical solution will be supplied. You can increase the crack, place the strengthened screed or use the heat insulating panels. In addition, if there is a need to identify the weakness of the soil, additional cementation of soil should be carried out under the foundation.

If a tape foundation needs in treatment, then proceed in this way:

Strengthen the base with the help of burbill piles that will help protect the tape from sending to the soil. To avoid destruction, torn the cracked foundation of the bouncements. Piles are placed under the sole in the form of a X-shaped support, fixing them with a clamp. The design will take an effort that breaks the foundation.
Strengthen the soil with a drainage system, which increases the depth of groundwater and reduces the soil radiation.
To reduce the depth of the primer of the soil, is equipped with thermal insulating gem.
The crash and junction itself between the foundation and the installed elements are poured with concrete.
After that, it is recommended to put a mark that displays the current position and condition of the crack.
In addition, between the edges of the crack, it is recommended to pull a thin wire using epoxy mass and observe its behavior. If it does not break through the winter-summer period, the destructive process has been successfully stopped.

The slab foundations are rarely destroyed, they are inherent in a high bearing capacity. But in case of such trouble, be prepared for a complete or partial replacement of the base, since the destruction will not work. It is necessary to make a subcople under the stove, remove the damaged part and make a new part of the foundation.

Thus, if the foundation cracked, immediately proceed to the examination of the defect, its size, directions, etc. This will help to understand why it happened and how to fix the situation.
