Repair and suturing cracks in walls and foundations

By closing your eyes to cracks in the walls of your building, you can skip warning signs of serious and non-stop damage.

Cracks on the walls are common in buildings since the erection of the first house in humanity and (let's not dissemble) in modern houses and structures for various purposes. Although some damage should not be worried, others may indicate a subsidence or damage to the foundation and, as a consequence, the walls. If you do not repair the problematic cracks in the structures, damage to the foundation can quickly devalue your property and lead to an unsafe condition.

When do cracks on the walls indicate a serious problem?

         Large cracks (vertical, horizontal, diagonal) can indicate weaknesses in the foundation or foundation of your object, as well as:

  • One side of the wall is higher than the other
  • Doors and windows no longer close easily or are skewed
  • Cracks opening wider than 1 mm or they develop in time

          Problem cracks usually start at windows, doorways, or corners of a building. However, if you find small cracks of a hairy nature, but they (which is important) have no development, then most likely these are cracks in the decorative layer and are not worth the bother. They can be planned budgeted and easily fixed without consequences for the entire building. However, in any case, it is worth consulting with a civil engineer, and preferably with a survey engineer.

What causes the development of cracks on the walls?

          Large cracks can appear due to the fact that the foundation of the object has lost its structure and strength, as a result of which all or part of your structure sags. This usually happens because the density of the soil under the settled part of your real estate is too low. It is also very important to understand what part to sit down. Often, intuitively, we make the wrong conclusions about this. The second important cause of cracking is the incorrect distribution of stresses in the structures. For example, failure to comply with standards during design or construction and incorrect location of expansion joints in structures (or their absence at all). Well, in our practice in the Russian market, a frequent case is an incorrectly erected roof.

How to fix cracks in the wall?

          First, consult with a survey engineer (who is also a designer) to assess the cause of the crack and recommend a solution, and then contact a Uretek expert (usually a geotechnical engineer). The best long-term solution for repairing large cracks is to lift the structures to the design position and then reinforce them with reinforcement. That is, reinforce the load-bearing nodes of your building. This complex process is called by one term “amplification” and often confuses owners, because it is a two-stage process. As the structure aligns with the design marks, cracks can close or decrease (then the walls are sewn together with spiral reinforcement and finished). Windows and doors also tend to start working properly again.

          In general, there are two ways to solve the problem:

The traditional method:

          This includes excavation or excavation of parts of the foundation, pouring concrete (or cementation), waiting for the composition to cure, or installing piles. However, these methods will not help to sew up the cracks and cannot confirm the result, which in turn:

  • time-consuming (often takes weeks or months)
  • noise, dirt, mess, with the need for restoration work after the project
  • it also means that you will have to vacate part of your building and provide space for a temporary construction site.

Modern Uretek resin injection method:

         As in the case of surgery, the expanding Uretek resin is introduced into the necessary areas under the foundation through tiny holes (usually up to 28 mm, but not more than 8 mm when working inside the house). The resin expands to fill the voids and compact the loose soil, exerting controlled pressure to raise the structure back to the desired level. The process is prescribed and carefully monitored using laser equipment. This method may be a good option because it:

  • rarely takes more than three days
  • does not require you to move out or vacate the area
  • lack of excavation and excavation (so there is no mess and dirt)
  • may take into account the location of furniture or technological equipment, as well as the presence of floor coverings
  • can be carried out outside the building (even if the problem area is inside), so this does not interrupt everyday life

         Uretek resin injection technology is a proven method for strengthening the foundation of a house and walls (in conjunction with reinforcement). It complies with all national requirements and building codes.

CRACKING IN THE FOUNDATION AND WALLS MAY BE CAUSED BY THE FOLLOWING FACTORS:

  • Not properly tamped base
  • Additional new structural load
  • Man-made breakdowns and accidents of engineering communications
  • Regular fluctuations in moisture and soil temperature
  • Earthworks or piling nearby
  • Structural differences of foundations within the same building
  • Regular exposure to vibrations
  • Diverse base under one building
  • Biological processes in the soil

AS A RESULT OF APPEALING TO URETEK, YOU CAN:

  • Understand what is happening
  • Make an informed and informed decision.
  • Take control of an asset
  • Increase facility life
  • Stop Lost Asset Value
  • Choose the most suitable way to implement the solution.
  • Get a reliable expert in building maintenance
