Foundation Problems: Why does Concrete Crack and What to do About it?


For a building to be strong, it requires to have a strong foundation. This can be achieved only through the use of the right materials and the right experience. As such, the foundation is an important part of the building that is used to transmit its weight to the underground or the surface beneath it. In this regard, it is important that the foundation constructed be strong enough to support the building and its weight and more to that from the strengths that may result from surrounding sources.

Why does Concrete Crack?

In most cases, concrete is used as the main element in construction of foundations. However, it is bound to gain cracks if it lacks in certain elements. For cracks to develop, it is as a result of restrained movement of the concrete and exposure to a force that it fails to withstand. The common causes of cracks include among others shrinkage, corrosion, chemical effects, and overload.

Shrinkage normally occurs a few days after the concrete is poured. It is mainly a result of inadequate reaction of the chemical adhesives within the concrete a process that is enhanced by curing through water. Chemical reactions occur when substances are exposed to the floor and those that contain elements bound to react with the chemical composition of the concrete. Overloads are normally prevalent when the structure constructed goes beyond the stipulated weight or height or when heavy objects are moved or placed above the concrete.

What to Do About It

Cracks can easily develop into disasters. It is for this reason that adequate measure to prevent the cracks should be put in place. They include among others ensuring that the correct mist of concrete is made with the correct ratios considered. In this way, a strong adhesion is ensured. More to this, proper curing should be observed. This includes adequate supply of water during the period of curing and measure to prevent rapid evaporation hence drying.

Any chemical used on the slab either for industrial or cleaning purposes should be chosen and used with caution. This will ensure that no amount of such substance is allowed to get into contact with the slab and as such reduce chances of corrosion. During the design of the building or structure supported by the slab, weight is determined. This requires to be followed to the letter to ensure that the weight is ideal to be supported by the concrete with no crack developing.
