Concrete is a very strong substance. However, it is not impervious to the elements, and over time, it will develop cracks and other problems. Fortunately, most concrete driveway cracks are generally affordable and simple to repair. The focus of this article is on finding concrete cracks. We go over the common reasons for concrete cracks, why they happen, and how to repair them.
CONCRETE CRACKS OCCUR FOR A VARIETY OF REASONS
It's essential to understand why concrete cracks in the first place before deciding to repair it.
Understanding what causes concrete cracks will help you avoid making the following three mistakes.
1. The concrete mix had too much water.
Despite the fact that concrete does not require a lot of water to reach its optimum strength, the majority of concrete that is poured has too much water added to the mix on the job site.
This is because the extra water makes pouring and spreading concrete easier and faster.
Shrinkage occurs as a result of excess water, which leads to cracking.
Evaporation causes shrinkage when the concrete hardens and dries.
The more amount of water in the concrete mix, the more shrinkage there will be.
This shrinking exerts pressure on the slabs, causing them to separate.
2. The concrete dried too quickly.
Concrete that dries too quickly is weaker and more prone to cracking. When concrete transitions from a liquid to a solid-state, the chemical reaction takes days or weeks to complete. To ensure that the concrete does not dry too quickly, it is often "cured" by flooding or spraying it with water. This ensures that the concrete dries slowly and evenly.
3. The concrete strength ratio is off.
Concrete can have a wide range of strengths depending on how it is poured and cured. A high-rise building's foundation/floor, for example, will need to be much stronger than a residential driveway's. Depending on the situation, cracks (or bigger problems) are likely to appear sooner rather than later if the proper strength is not achieved.
HOW TO REPAIR CONCRETE CRACKS?
Repairing concrete cracks improves the appearance of your driveway while also protecting it from the elements such as rain, snow, dirt, and etc.
The first step is to prepare the area. Use a cleaner that is specifically designed for the job at hand.
If the concrete in your garage has become covered with oil and other vehicle fluids, for example, use a cleaner containing a grease-cutting agent.
Step 2: Undercut the crack's edges with a clean chisel and small sledgehammer for wider concrete cracks.
This is known as "keying," and it widens the crack's base compared to its surface, allowing for a more secure and long-lasting repair.
Step 3: Remove debris and dust from the crack by sweeping and cleaning it.
A whisk broom and/or a vacuum cleaner should do.
Step 4: Use a concrete filler to repair the crack.
Make sure to follow the patching material's instructions and work slowly.
Check back in a few minutes to examine how the filler has settled into the crack after you've finished filling it.
If it doesn't seem full and snug, you may need to add extra.
When you're done, smooth out the cracks.
Step 5: Follow the manufacturer's instructions for curing the patch.
Check back once the time has passed to see whether another patch is needed.
Step 6: Seal the patch.
Because concrete is porous and absorbs moisture and stains, it is necessary to seal it after repairing it for the best results.
