Common Concrete Problems We Fix
As concrete hardens and dries it shrinks, because of water that evaporates from it. If there is excess water in the freshly poured concrete, or water from the building settling, the shrinkage rate will be increased which will result in cracks.
Though shrinkage is one of the main reasons for cracks in concrete, fluctuating temperatures within an environment can also cause concrete to crack.
Concrete spalling is the breakdown of concrete that is caused by standing water, natural weathering, and chemical reactions. This breakdown can result in areas of cement chipping off from the main body, which can lead to fractured and compromised concrete.
What exactly does concrete spalling look like? Spalling concrete can often look like round or oval dents along the surfaces of cement. This problem tends to occur more commonly in cold climates when de-icing chemicals are applied to the concrete or when seasonal freeze-thaw cycles damage the concrete.
The reasons for concrete becoming uneven can vary but can be pinpointed down to a few primary causes, such as water issues, dry soil conditions, poor compaction, and pest and animal influences.
In terms of concrete floor bulges, this happens when there is a plumbing leak. When clay absorbs water, it will naturally expand which creates an intense force on the concrete floor causing a bump to develop.
