How do I Build Concrete Circular Steps?

By Erica Porter

Many homeowners are scared to build anything that makes use of concrete. They immediately think that the process would involve heavy construction and complicated designs. But what if you have no one to help you create your concrete steps? If you want to create the perfect concrete steps that go well with your preferred shape, it is best to learn to do the process yourself. Circular steps are just one of the many rare designs of concrete steps. The process of finishing one requires a few materials and tools.

Excavate the area where you will build your new steps by digging a few inches down the ground using a shovel. Dig around 6 inches wider on each side of the step.

Use your electric drill to make evenly spaced holes into the vertical surface where you will build the steps. Insert a 12-inch standard reinforcing rod about 3 inches deep into every hole.

Build the circular form of your steps, using your drywall screws and coated lumber. The size of the circle will depend on how big you want your steps to be. Cut two side pieces according to the specifications of the side of the steps. Install these pieces, using your short 2-by-4 boards where your steps' sides should be placed. Nail the coated 2-by-4 boards across each of your stair-stepped areas of your side boards.

Fill the form of your circular steps with broken chunks of solid masonry. Arrange the fill of your steps so that it is at least 4 inches from all edges, including the ones on top.

Pour your prepared concrete into each step mold from the bottom of the frame. Allow the concrete to level for one to two hours. Use a piece of your scrap-coated lumber to tamp the concrete carefully. Use your metal screed to screed the surface of your steps.

Use your finishing trowel to smooth the surface of your circular steps. Level the inside corners of your steps, using the trowel, and finish its edges by smoothing them with your edger tool.

Allow the concrete circular steps to cure for five to seven days before you remove the coated lumber forms.
