Repairing Crumbling Concrete Steps

Posted on

If you have a staircase that has a few steps that are crumbling along the edges, you will want to work quickly in having them repaired to avoid injury and extensive damage. While most people will hire a masonry contractor to do the job efficiently, you may be able to tackle the project yourself if you have a bit of time and the proper tools. Here are some instructions for you to follow when repairing crumbling concrete steps.

Materials You Will Need

  • Pressure washer
  • Mild detergent
  • Sponge
  • Vegetable Oil
  • Pieces of plywood
  • Bricks or cinder blocks
  • Ready-to-mix concrete
  • Large bucket
  • Mixing utensil
  • Trowel

Cleaning The Area

Before you make a repair, clean the steps completely so there are no areas of dirt embedded in the concrete, causing it to look discolored as a result. Wipe down the steps using a sponge dipped into a bucket of warm water with a few tablespoons of mild detergent added. Rinse your staircase using a pressure washer. You may notice a few more pieces of concrete disappear from the edges at this time, but since they were deteriorating it is best they are removed before you start adding concrete so the steps will be sturdy when the project is completed.

Preparing The Form

To repair broken steps, you will want to make a form to pour the new concrete into so it is contained for several hours, allowing it to harden into the desired shape. Use pieces of plywood to reform the sides of the steps that have started crumbling. Cut the plywood pieces to the height of each step. Make them wide enough to overlap portions of the step that are still intact. Use a paintbrush to apply vegetable oil to one side of each of the plywood pieces. This side will face the steps, allowing you to easily remove the form after the concrete has hardened. Place them up against the front and sides of each step you are going to repair and set bricks or cinder blocks in front of the plywood pieces to keep them in place.

Adding The Concrete

Place ready-to-mix concrete into a large bucket and add water according to the package directions. Mix well and pour over the areas of the steps where crumbling occurred. The plywood pieces will keep the concrete in place. Use a trowel to smooth the concrete along the top of each step. Allow the concrete to harden for a full day before removing the bricks or cinder blocks and plywood pieces from around each step. To learn more, contact Mara Restoration, Inc.
