Type, size and location of cracks Important to take into account when determining the cause of the problem

Not all cracks are the same.Type, size and location of cracks It is important to consider when determining the cause of the problem, as well as to address the solution to solve the problem.

Similarly, the assessment of the success of the recovery project is based on a combination of advantages, deficiencies and risks of instant and pending.

Different types of cracks on the walls:

The most common types of cracks in the walls are:

- Internal cracks, striking plasterboard, plaster, brickwork or monolith

- external cracks in the brick (and any other stone) masonry, monolith or on the plaster of the outer walls

If the cracks on the walls suddenly appeared in your home (not to be confused with a sudden detection, because you could simply not pay attention for a long time), then they can be a symptom of a deeper constructive problem.

Smaller hair-type cracks are quite common in the walls and usually do not cause concern from the owners of the property.Larger cracks that begin on the windows, doorways or corners of buildings may indicate that the foundation of the building failed, she asked or lost strength, as a result of which all or part of the building suffer drawdown.

Pay attention to whether a crack is disclosed or not, horizontal or vertical, zigzag, stepped (for example, in a brickwork) or follows the lines of joints in nodes. If the crack is at least one place in everybody with its length of 5 mm or wider, or you noticed the full separation in the design of the node (in solution or cement between bricks), it is recommended to seek professional advice. In other cases, you should not leave the manifestations of destruction without attention, and in any case to make a plan of observation, and inspection of the structure at least 1 time per month with fixation state of structures at the time of inspection.

Recovery Process:

After the main reason was defined as a sedimentation (drawdown) or reduced bearing capacity, you should always consider several solutions.In this set, traditional methods of strengthening or non-invasive method of injection, which is much more prompt and gentle with a more cost-effective result.

The injections of the Граундтек resin are designed to be applicable locally in precisely defined drawdown zones and the weakness of the base under construction. Using a process similar to surgery, the method increases the carrying capacity of the soil and levels the building with high accuracy. Whether the cracks are completely closed or not, depends on the direction of the crack and the state of the base under your home. That is, the main question is whether the design is capable of perceiving the strength of alignment? In the overwhelming majority of cases, houses and designs can be aligned during the day using technologies Граундтек, and the process itself is rigidly controlled by constant control using laser levels to ensure accuracy.

Cheap way to organize observation:

In everyday life for observation of the behavior of structures, in addition to professional lighthouses, a special indicator is applied - a tape that is attached to significant cracks in the wall. This visual indicator is one of many measurement methods that technical specialists are used to carefully monitor changes throughout the controlled recovery or observation process. Even for the untrained eye, it is possible to detect the visible movement or deformation of the tape due to the movement or deformation of the structural parts on which it was applied. The tape can also show how the design moves in response to restoring the level of the foundation, including the direction and degree of lifting.

However, it is necessary to understand that the tape is very sensitive to external environmental conditions.Humidity, external effects and temperature differences can disrupt the mount and distort objective information.To achieve the best long-term results after restoration work, Граундтек recommends organizing the geodesic monitoring of the building status and regular inspection of nodes and structures.

And after the work on strengthening the foundation, what to do with cracks and do you need something to do with them?

We recommend a crack strengthening to preemptively close the collapsed design.Methods are different, but we consider the tested and reliable and we use the enhancement of special twisted reinforcement.After such treatment, we are ready to guarantee work up to 50 years.

It is wonderful that there is no serious consequences.But still we would recommend to conduct a survey of structures and foundations.The cunningness of the drawdown is that it proceeds very often not linearly ... and smooth development is replaced by a sharp change in the situation.

This must be at least 2-D beacons, fixing movements in two directions with a scale of measuring these displacements.Lighthouses are simply fixing "microwork" is not enough to fully track the behavior of the designs.

If the crack goes diagonally along the wall, but very thin, whether it is worth worrying.Maybe wait until it is more noticeable and then to do any action!?

You like the owner or the user to decide when this crash will be a threat to calm or wallet.We can examine the building and evaluate the scenarios and the risks of the development of the future situation.

There are no clear criteria, unfortunately, no ... cracks are just one of the manifestations of the problem, that is, the consequence.Reasons This is an indication of what we must look for the cause of destruction and assessing it, you will answer questions about the danger and trends in the development of problems

Aleksej Karpovich (inzhener GROUNDTEK) Dec. 27, 2020

It all depends on the size of the cracks.The answer is clear about large through cracks.Small cracks can be examined by the extender for 100% diagnostics.Modern ultrasound or radar devices are used in more gentle methods.
