How To Build A Concrete Patio Slab

Building a concrete patio slab is a great way to add outdoor living space to your home. It's a relatively simple project that can be completed in a weekend with the right tools and materials.

Materials You'll Need

Concrete mix
Sand
Gravel
Rebar
Concrete forms
Trowel
Edger
Broom
Water

Steps

Prepare the site. Start by clearing the area where you want to build your patio. Remove any grass, weeds, or other debris. Then, excavate the area to a depth of 6 inches. The excavated area should be level and compacted.
Build the forms. The forms will help to hold the concrete in place while it cures. To build the forms, you can use wood or metal stakes and 2x4 lumber. Drive the stakes into the ground around the perimeter of the patio, and then attach the 2x4s to the stakes to create the form.
Place the gravel. The gravel will help to provide drainage for the patio. Spread a layer of gravel over the excavated area, and then compact it with a tamper.
Place the rebar. The rebar will help to reinforce the concrete and prevent it from cracking. Cut the rebar to length, and then place it in the gravel in a grid pattern. The rebar should be spaced about 12 inches apart.
Mix the concrete. Follow the instructions on the concrete mix bag to mix the concrete. The concrete should be mixed until it is smooth and free of lumps.
Pour the concrete. Pour the concrete into the forms, and then use a trowel to level it. The concrete should be about 4 inches thick.
Smooth the concrete. Use an edger to smooth the edges of the concrete, and then use a broom to texture the surface of the concrete.
Cure the concrete. The concrete will need to cure for at least 28 days before it is fully hardened. During this time, it is important to keep the concrete moist. You can do this by covering it with plastic or by spraying it with water several times a day.

Tips

When mixing the concrete, be sure to add enough water to make it workable, but not too much water. The concrete should be wet enough to pour easily, but not so wet that it is runny.
When leveling the concrete, be sure to use a level to make sure that it is flat. This will help to prevent the patio from settling unevenly.
When texturing the concrete, be sure to use a broom that is clean and free of debris. This will help to create a smooth, even texture.
During the curing process, be sure to keep the concrete moist. This will help to prevent it from cracking.
