Concrete is an awesome product, although it’s not perfect. Nothing is. There are just too many variables in the mixing, placing, and finishing of the concrete. Most of these problems are either avoidable or repairable though. A large amount of the time, most problems are the result of mistakes made with the finisher that is chosen. Most times, the builders (or general contractors) will choose the lowest bidder, which means the least amount of labor hours to get the job done. This also means that they will use a lower cost (cheaper) and lower quality concrete. This means it will have low compressed strengths less expensive mixtures. Most problems arise with the improper installation of the concrete.
For instance, Cracking. There are so many reasons why concrete cracks. It’s almost impossible to know the exact cause. However, cracks rarely result in structural problems. Cracks can be caused by too much water in the mix. Some contractors add extra water to make it easier to finish out the concrete before it dries, because they don’t have enough man power available to do the job properly. As the product dries, it will shrink as the extra water that was put in evaporates.
Improper strength for the slab/lot. Many people are unaware that there are different strengths available in concrete. You don’t want to drive an 18 wheeler over a lower strength concrete as it will crack and break down.
Many times the concrete will crack because there is a stress that exceeds the tensile strength of the concrete. Tension control joints should be placed in the right places to alleviate those stresses. If placed improperly, or if too few are placed, the concrete will crack under the stress.
