There are times when the wall as an important element of a house or building experiences problems, including the appearance of cracks in certain parts of the wall. Factors that cause structural cracks, for example, there is soil movement, sinkage or displacement or subsidence in the foundation structure. This is due to changes in soil characteristics due to floods, earthquakes, or other natural disasters. Error calculating the load that will be borne by the foundation during the construction process and the process of working on the structure of the building is imperfect. So that in the calculation, the strength of the building is not fulfilled. Make sure you call underpinning in melbourne service to help you fix the problem with underpinning method.
Solutions to overcome structural cracks include structure crack due to the lower foundation because of making new adjacent foundations or conduct soil compaction under the new foundation. It could also be caused to make a new column/pole so that the load distribution from the slot and ringbark can be perfectly distributed. Structural cracks in building support columns could be fixed by creating additional columns to divide the existing load on the damaged column. Strengthen the column by injecting it with epoxy liquid to strengthen the column then widening the column size will also help. Minor structural cracks in beams or columns can be done by covering the cracks with plaster so that the steel reinforcement inside is not exposed to outside air which can cause rust.
Control the flow of water around the building foundation to prevent it from occurring under the foundation that can cause cracks in the walls. Non-structural cracks are generally not dangerous but reduce the aesthetic value of the building. The main characteristic of non-structural cracks: the presence of soft lines with irregular directions. Cracks that occur due to the use of too much cement, plaster that is allowed to dry too quickly, a mixture of plaster that is too thin and not completely dry, and the use of less quality wall paint. For cracks that occur due to high cement content, poor sand quality and too thick plaster applications. The solution is to use putty on the part that has cracks.
