When it comes to concrete works, there’s no margin for error. Whether you’re building a patio, driveway, or parking lot, cracking and other failures of the finished product can result in costly repairs.

Considering that, it is always preferable to prevent rather than to treat! So here are six measures to take when working on ready-mix concrete, prevent the finished surface from cracking altogether, and make sure that it stands the test of time. 


1. Make sure the concrete-mix ratio is correct.

When you order ready-mix concrete, discussing your project with the supplier is essential. They’ll be able to tell you the best ratio for your project and answer any other questions about concrete that you may have.

Get it wrong, and you’ll regret it!


2. Properly prepare your subgrade and base layer.

It goes without saying that the surface your concrete rests on will significantly impact whether it cracks down the line.

The subgrade should be free of any organic matter and compacted so that it is firm and even before you pour in the ready-mix concrete. Depending on your project’s requirements, the base layer should also be properly prepared with gravel, sand, or other material.


3. Use steel reinforcements and control joints.

Using steel reinforcements, such as rebars and meshes, helps to ensure that the ready-mix concrete has something to hold on to and prevent it from cracking afterward. Control joints are also a great way of controlling where potential cracking occurs. This gives the concrete somewhere to go when it starts to shrink or expand over time instead of making its own random cracks.


4. Spray-cure with water.

Once the concrete has hardened, it’s important to spray-cure it with water. This helps keep the surface moist and prevents it from drying too quickly. If this happens, the concrete can be prone to cracking or other issues due to thermal shock.


5. Observe proper curing time.

The curing process is an essential part of ensuring that concrete doesn’t crack. This process can vary depending on the ambient temperature, but as a rule of thumb, you should give it at least 28 days before subjecting the concrete to any heavy traffic or other forms of stress.


6. Apply a waterproofing membrane and some sealants.

After curing, you can apply a waterproofing membrane and sealant to the concrete surface to protect it from outside elements that could cause cracking. This is especially important if your project will be exposed to water or frost.

Waterproofing membranes and sealants act as a barrier between the concrete and any potential sources of damage, so they should not be ignored.

By following these steps, you can prevent your concrete surface from cracking and enjoy it for years to come.
