Concrete is one of the most compact and durable materials you can use to construct structures around your home. With a concrete slab, you will stay lest assured that you will have a mind-blowing structure in your American home for many decades to come.
In the world we are in, even the legendary human beings of all times such as Mother Teresa had their own flaws. Nothing created by nature or man comes without its set of drawbacks. Even with its astounding capability to stay for long, a concrete slab is prone to cracking. Most homeowners who have invested in it will get annoyed and start causing their contractors for a shoddy job when the slab starts to develop visible cracks with time.
The question commonly asked is; why does a concrete slab crack? Actually, it is not always because of a shoddy job or lack of skills. It is because of either of the following reasons.
Having excess water in the mix
Even the best concrete contractor in America will tell you that concrete does not require a lot of water in order to achieve its maximum strength. However, most contractors add a lot of it while laying concrete slabs because their dream is not to achieve strength, but to make it easier to install, finish the job fast, and secure a new contract. This is a dangerous move.
A concrete slab with excess water will dry, harden, and shrink hence causing visible cracks. To avoid this, make sure you choose a reputable concrete contractor, who will have enough manpower and skill to stir a stiff mix and build you the home of your dreams. Most importantly, have the knowledge about how much water can be poured into concrete, information that is readily available over the internet, and then go for a contractor who will dedicate all the time for your project.
Rapid drying of the concrete
For a concrete slab to realize its maximum strength, it must be allowed ample time to dry. If you are in haste to put up your structure, you might end up using a concrete slab that has rapidly dried, which increases the possibility of cracking within a short time. To avoid this, make sure you give the slab adequate time to completely cure.
Pouring concrete with improper strength poured
Concrete comes with different strengths. A concrete slab that will come with an improper strength is prone to cracking, thus you should verify its strength before pouring.
Pouring concrete on frozen ground
This is another cause of cracks in concrete. If you pour it on frozen ground, it will absorb excess water, thus making it weak. As it dries, massive shrinkage occurs which is a major cause of cracking.
Lack of control joints
Control joints will help the concrete slab crack where you want it to. If you don’t install them, your slab will crack at will and you might end up spending a lot on repair and maintenance.
These are some of the factors that cause your concrete slab crack. You don’t have to always blame it on your concrete contractor!
