How To Replace Concrete Patio

How to Replace a Concrete Patio

Concrete patios are not complicated, but they are physically demanding to install. The average cost of replacing a concrete patio can range from $10 to $15 per square foot, but doing it yourself can save you about half of the cost of hiring a professional concrete contractor.

Replacing a concrete patio yourself is possible if you have some basic construction skills and are willing to put in the effort. Here are the steps on how to replace a concrete patio:

Step 1: Remove the Old Patio

For smaller patios, you can attempt to use a sledgehammer to break up the concrete. For larger patios, you will need to rent a jackhammer. Wear appropriate safety gear, such as safety glasses, gloves, and earplugs.

Step 2: Prepare the Base

Once the old patio is removed, you need to prepare the base for the new patio. This involves leveling the ground and compacting it. You can rent a plate compactor to make this step easier. The base should be at least 4 inches thick.

Step 3: Set Forms and Pour Concrete

Next, you will need to set the forms for the new patio. These forms will determine the shape of the patio. Once the forms are set, you can begin pouring the concrete. Start at one end of the patio and work your way to the other. Use a screed to level the concrete as you pour it.

Step 4: Trowel and Finish

Once the concrete has been poured, use a trowel to smooth out the surface. You can also use a bull float to give the concrete a smoother finish. Once the concrete has set, you can remove the forms.

Step 5: Let the Concrete Cure

The final step is to let the concrete cure. This process takes about 28 days. During this time, you should keep the concrete moist by covering it with plastic or burlap. After 28 days, the concrete will have reached its full strength and you can start using your new patio.

Tips for Replacing a Concrete Patio

Here are a few tips to help you replace your concrete patio:

Choose the right concrete mix. There are different types of concrete mixes available, so be sure to choose one that is appropriate for your project.
Follow the manufacturer's instructions for mixing and pouring the concrete.
Work in small sections. Don't try to pour the entire patio at once. This will make it easier to control the consistency of the concrete.
Don't overwork the concrete. Once it has been poured, smooth it out with a trowel or bull float, but don't overwork it.
Let the concrete cure properly. This is an important step that cannot be rushed. Covering the concrete with plastic or burlap will help it retain moisture and cure properly.
