Property owners are often shocked to see unexpected cracks in their concrete. Concrete is a very durable material for construction but it does have its own shortcomings. In fact, concrete cracks are quite common and there can be a number of factors that contribute to it:
Shrinkage and evaporation
One of the main reasons for cracked concrete is shrinkage. Concrete is mixed with water when it is poured. As it hardens and dries, it shrinks as the water evaporates from the mixture. When mixed with a lot of water, there can be a lot of shrinkage and evaporation and that can easily result in cracked concrete. There are also several structures around and in the concrete when poured and this can also result in cracks. When water from freshly poured concrete evaporates faster compared to the concrete under, cracks can appear.
As temperature falls and rises, concrete can contract and expand. The temperature of the interior and surface concrete can be different at times. When this temperature difference is too high, concrete cracks can appear quite easily.
In many instances reinforcing steel or other metals are used to hold concrete together. When this metal corrodes, the rust on the metal will take up a lot of space. As rust grows, the concrete will be stretched. This increase in stress will crack the concrete surface in many cases.
Structures and buildings settle over the years. As the soil under concrete slabs washout or settle, the support to the foundation will become uneven. This uneven support is extreme unsafe and unstable and it is also one of the most common reasons for cracked foundations.
Even some of the smallest concrete cracks can grow more serious and larger over time. If you notice any cracks in or around your property, repair them instantly with Flexomeric crack repair products
