A cracked concrete slab is an eye sore and an issue of sanitation. In addition to being an unsightly eye sore, cracked concrete can be a problem of maintenance. If the crack occurs on a high-visibility area, it needs to be fixed quickly to prevent further damage. Read on to learn more about the reasons behind concrete cracking and how to stop it. We also cover some tips for preventing future cracking and how to fix it.
The most common cause of concrete cracks is contraction and expansion. The ground on which the concrete is placed can cause it to expand or contract. The ingredients and mixture of concrete contribute to this process. Weather conditions can also cause these changes. It is important to know how to prevent cracks when you notice them. The best solution is to take care of them as soon as they start. This will prevent any further damage and ensure the long-term durability of your concrete.
The most effective method to prevent cracks in concrete is to place it on an even substrate. The first step is to restrain the concrete during installation. If you are installing concrete on a slab, you can use reinforcing steel to keep it in place. If the slab is not supported by reinforcing steel, vertical cracks may occur. Both types of cracks are damaging and require immediate repair.
A second reason for concrete cracks is ground movement. In addition to freeze-thaw cycles, heavy objects can cause the ground to move. The weight of a car, truck, or other vehicle can push a slab several inches above its level. In addition, a large tree root may bury a concrete slab and cause it to heave. This is known as subsidence. Once the tree has been cut, the ground will thaw and settle again.
While the most common reason for a cracked slab is expansion, other factors can also cause the slab to crack. Hot weather can cause concrete to expand, forcing it to push against anything in its path. If it’s already cracked, this can result in an aesthetic problem. Often, this is the type of cracking that’s most easily repaired. Adding the proper amount of water to a concrete slab can increase the strength of the slab.
A cracking slab is not always a foundation issue, but it can be a major problem. Some cracks occur when the ground freezes, causing the slab to shift. If you don’t do something to stop this from happening, you’ll risk losing a lot of money and your home. You should keep an eye on the condition of the cracked slab and the soil around it. It’s best to get a professional to look over the cracked concrete and find the right solution for you.
