Severe concrete floor cracks due to poor curing usually require repairs as they can compromise the floor’s structural integrity. As such, if the process is unprofessionally done, the concrete surface is likely to suffer map cracking, whereby the surface concrete shrinks faster than the concrete below the surface due to faster drying. Concrete curing is usually done to help with moisture retention thus preventing rapid moisture loss that facilitates cracking.

Improper concrete curing- poorly-cured concrete is bound to start cracking at an early age.

A properly prepared, smooth subgrade inhibits concrete cracking by minimizing restraint during concrete shrinking.

Sub-par subgrade- to establish a proper base for your fresh concrete surface, you need to ensure that sub-grade preparation is done the right way with a smooth, even, and frost-free sub-grade being recommended if you’re looking to avoid concrete settling and cracking.

Too much water in the concrete mix – this causes more drying shrinkage as the extra water evaporates away, thereby increasing the chances of cracks developing on your floor.

The following are some of the reasons why you may develop cracks on your concrete surface:

In addition, when the internal tensile stress exceeds the tensile strength of the concrete, it can form gaps and crevices on your concrete floor. All the factor that facilitates drying shrinkage can also trigger and accelerate concrete cracking. It’s where plastic concrete sets, hardens, and starts to shrink by 12.5% for every 20-feet. The common cause of concrete cracks is drying shrinkage. Identifying the causes of cracks in a concrete floor is the utmost step to fix it. How do I Prevent Shrinkage Cracks on Concrete Floors?.
