How to Repair Holes in Concrete Floor

If you have a concrete floor in your house or workplace, you may have noticed cracks or holes appearing over time. These can be unsightly and create tripping hazards, but fortunately, repairing holes in concrete floors is a doable DIY project. Here are some steps to get you started:

What You’ll Need:

  • Chisel and hammer
  • Clean brush
  • Vacuum cleaner
  • Cement or concrete repair mix
  • Trowel
  • Water
  • Patch

Step 1: Preparation

Before you begin, you need to make sure that the hole is clean and free from debris. Use a chisel and hammer to remove any loose concrete around the edges of the hole. Then use a clean brush to sweep the debris out of the hole. Use a vacuum cleaner to thoroughly clean the hole and surrounding area.

Step 2: Mix the Concrete Repair Mix

Next, you need to mix your cement or concrete repair mix according to the manufacturer’s instructions. Be sure to mix it well. You want the consistency to be thick but not too dry.

Step 3: Apply the Concrete Repair Mix

Now it’s time to apply the concrete repair mix to the hole. Use a trowel to apply the mix, pressing it firmly into the hole. Use the trowel to smooth the surface of the mix so that it’s flush with the surrounding concrete. Check to make sure that the patch is level with the surrounding floor.

Step 4: Let the Mix Dry

Once you’ve applied the concrete repair mix, you’ll need to let it dry for at least 24 hours. Don’t step on it or put anything on it during this time.

Step 5: Finish the Patch

Once the mix has dried completely, you can finish the patch. Use a fine-grit sandpaper to smooth the patch until it’s level with the surrounding floor. Then, clean the surface with a damp cloth and allow it to dry.


In conclusion, repairing holes in concrete floors is a manageable DIY project that can save you money on professional repairs. With some simple tools and the right materials, you can restore your concrete floor to its former glory.
