It may seem to be a panicking situation for you to find a crack in the concrete slab you have installed a few months back, but to your surprise, it’s quite common. If you listen to the experts in the field, you should be prepared for this to happen as there have been a lot of cases, where the crack appeared despite proper construction and material use.
However, not all types of cracks are the same and most importantly, most of those do not go beyond the concrete repair. The reasons behind concrete cracks are different from that of the standard wall cracks. So, before you start drawing the concluding line, you must learn about the different types of concrete cracks that keep on occurring.
Find out the source of your problem more specifically.
▪Expansion Due to Heat
This is probably the most common scenario people encounter regarding concrete cracks. If you blow too much air inside the balloon, it will automatically burst. According to the professionals of rendering in Sydney, heat does exactly the same with concrete.
The slab does not get a chance to get flexed and lead to a crack. The cracks usually get more prominent in the expansion joints. Using the right shock absorbers around those expansion areas certainly helps in the basic resistance.
▪Cracks During Plastic Stage
The word ‘plastic’ does not have a literal meaning here. Here, the word refers to the semi-liquid state of concrete when it is yet to get hardened. A lot of water still remains there and when it starts to dry up, it creates an empty zone inside the concrete.
The professionals of concrete repair suggest that the entire structure turns out to be weak and thus it becomes more prone to crack. This is often referred to as plastic shrinkage crack.
▪Low-Quality Concrete Mixture
Well, the reason often remains hidden in the beginning stage of the entire process. The use of low-quality concrete mixture for creating a concrete slab or wall leaves a lot of impurity in the construction. So, it is recommended to be a little careful since the beginning when the foundation is laid to make sure that only good quality concrete mixture is put to use and the ratio is just perfect.
▪The appearance of Crazing Crack Due to Fast Drying
You may often encounter some crazing hairline patterns on the concrete foundation. Those may seem to be normal patterns but in reality, those are concrete cracks. The experts of concrete repair say that if the concrete mixture gets dried up too fast, it may cause such cracks, but it is quite difficult to determine what exactly triggered the crack.
The experts suggest that attention to the site preparation, use of proper concrete mix and of course, the efficiency of the professionals creating the concrete slab can determine whether the cracks will be present there or not.
An endnote:
When the cracks have already appeared, the only way out remains is to fix those or hide those. The experts in rendering in Sydney give the assurance of doing both effectively. All you need is to sign up for a reliable professional for the job.
