Not all cracks are the same.
The type, size, and location of cracks are important to consider when determining the cause of the problem and to guide you in the right direction in your search for a solution.
Similarly, the success of a restoration project is based on a combination of immediate and delayed benefits, drawbacks, and risks.
Different Types of Wall Cracks:
The most common types of wall cracks are:
Internal cracks that affect drywall, plaster, brickwork, or masonry
External cracks in brick (and any other stone) masonry, masonry, or plaster on exterior walls
If cracks in your walls suddenly appear in your home (not to be confused with your sudden discovery, as you may have simply not noticed for a long time), they may be a symptom of a deeper structural problem.
Smaller hairline cracks are quite common in walls and are usually not a cause for concern for property owners. Larger cracks that start at windows, doorways or building corners may indicate that the foundation of the building has failed, sagged or lost its strength, causing all or part of the building to subside.
Pay attention to whether the crack is open or closed, horizontal or vertical, zigzag, stepped (for example, in brickwork) or follows the joint lines at joints. If the crack is 5 mm or wider at at least one place along its entire path, or you notice a complete separation in the structure of the joint (in the mortar or cement between the bricks), then it is recommended to seek professional advice. In other cases, do not ignore the signs of destruction, and in any case, draw up a monitoring plan and inspect the structure at least once a month, recording the condition of the structure at the time of inspection.
RECONSTRUCTION PROCESS:
Once the root cause is identified as subsidence or reduced bearing capacity, there are always several solutions to consider. This includes traditional reinforcement methods or the non-invasive injection method, which is the most rapid and simplified with a more cost-effective result.
Premium Technologies resin injections are designed to be applied locally to precisely defined areas of subsidence and weakness in the foundation beneath the structure. Using a process similar to surgery, the method increases the bearing capacity of the soil and levels the building with high precision. Whether the cracks in the walls will be completely closed depends on the direction of the crack and the condition of the foundation beneath your home. So the main question is – can the structure withstand the leveling force? In the vast majority of cases, homes and structures can be leveled within a day using Premium Technologies technologies, and the process itself is tightly monitored using laser levels to ensure accuracy.
A CHEAP WAY TO ORGANIZE OBSERVATIONS:
In everyday life, in addition to professional beacons, a special indicator is used to monitor the behavior of structures – a tape that is attached to significant cracks in the wall. This visual indicator is one of many measurement methods that technicians use to carefully monitor changes throughout the controlled restoration or observation process. Even to the untrained eye, it is quite possible to detect a visible change or distortion of the tape due to movement or deformation of parts of the structure to which it was applied. The tape can also show how the structure moves in response to the restoration of the foundation level, including the direction and degree of rise.
However, it should be understood that the tape is very sensitive to external environmental conditions. Humidity, external influences and temperature changes can disrupt the fastening and distort objective information. To achieve the best long-term results after restoration work, Premium Technologies recommends organizing geodetic monitoring of the building condition and regular inspection of nodes and structures.
