However, if curing is improperly done, the water evaporation will leave hairline cracks in the concrete slab. Concrete curing is a process that allows water elimination in a controlled manner. It has been established that rapid drying of concrete will cause cracks in floor slabs. In addition, the rapid evaporation of extra water from the concrete mix will shrink the drying solution leading to the formation of fissures or cracks in concrete floors. Surplus water in a cement mixture significantly raises the chances of a completed concrete slab developing cracks. An uneven or undulating surface increases the probability that the finished slab will buckle and break up as it dries. It is vital that an even surface is achieved before pouring a foundation slab. Uneven Sub-gradeīefore laying a concrete foundation, the soil surface or sub-grade is primed. The following factors will determine the chances of cracks forming in a concrete foundation. So, why does concrete crack? Various natural and artificial influences interact to cause concrete slabs to develop cracks. There are many reasons for cracks in a concrete slab and it is difficult to know exactly what will work best on a case-by-case basis. You may even notice cracks in walls and ceilings of the building.Ī cracked slab can pose a significant problem to the building and structures overlying it as they will develop distortions that translate into critical but unplanned maintenance expenditures. In severe cases, disruptions in slab continuity manifest as buckled walls with disfiguring cracks and crevices, leaning buildings, and broken-up floors with uneven or undulating surfaces. Structural cracks in cement slab foundations can adversely affect various parts of the overlying structure. What happens when you don’t fix foundation problems? You don’t want to know! Is a Crack in a Slab Foundation Bad?Ĭracks in a concrete slab can be signs of foundation issues, or they may just be superficial.
Early detection and repairs will ensure that concrete slab cracks don’t necessitate costly foundation repair methods. To prevent extensive damage and higher maintenance costs, you must monitor cracking and contact a professional in the case of widespread cracking and settlement.
The cause of unwanted cracks in concrete can be due to prolonged exposure to natural environmental forces such as: No matter how sturdy a concrete foundation is, it can develop cracks or fissures.
