Though concrete is prone to cracking, unfortunately, concrete that is free from cracking is not available. Temperature and moisture changes cause the concrete to expand resulting in cracking. Cracks may not be discovered once they develop in the substructure even after a long time. The owner of a building should be concerned about the emerging cracks regardless of when they were formed. Mostly, cracks tend to form at weak points such as walls, corners, and pipes of the substructures.
Additionally, cracks can form on buildings irrespective of how old the structure is. Some people think that new buildings are stronger and less prone to cracking. However, any problem, for instance, sagging on a building could result into a crevice despite the age of a building. Cracking highly compromises a building and if the cause of the cracking is not addressed, the building continually becomes weaker.
Several factors can result in cracking of a building substructure. One of the major factors is the moisture content in the soil. Too high or too low moisture could lead to the foundation of a building cracking. As water content in the soil increase or decrease it results in the movement of soil toward or away from the substructure creating gaps that give an allowance for the understructure to move resulting in cracks.
Earthquakes is another cause for cracks in the understructure. Once an earthquake occurs, it shakes the ground which in turn shakes the building. If the understructure is not stable, it can move around, become weaker and eventually may crack. A small earthquake, however, might not cause new cracks but may deepen the one already present.
Flooding and plumbing leakages can be disastrous. Excessive water causes soil expansion which in turn makes it push on the foundation. Moreover, exerting a lot of hydrostatic pressure to the understructure exposes more cracks and leaks.
However, there are some warnings before deeper crack can emerge. While the warnings are not a sufficient sign for a cracked substructure, they should be alert that some changes are happening. For example, jammed doors, cracks on the wall edges, around the windows and doors should send a signal of a change. With such occurrences, one should become more careful to observe the trend and pay more attention to the progress of the cracks.
Nonetheless, the building owner should not worry regarding cracks that have formed as a result of flooding and excessive moisture because they can be prevented using basement waterproofing techniques. Also, one can use epoxy injections to repair the cracks.
