You would think that concrete is the one doing the cracking, but instead, it’s the one getting the cracks. There are ways to fix that, though. The methods for fixing the cracks are dependent on the crack’s size. We’ll show you how to fix both narrow and wide cracks in concrete – just read this article.

How to fix narrow cracks:

  • Use a wire brush and broom to remove loose debris from in or around the crack.
  • Use a caulking gun and masonry crack filler and apply it to the crack. You can also use vinyl concrete patching compound too – apply it and smooth it with a knife.

How to fix wide cracks:

  • Chisel the edges of the crack with a small sledgehammer to undercut it. This will make it wider at the bottom than at the top, thus resulting in a safer and more permanent repair.
  • Use a wire brush and broom to clean up the area in and around the crack and then wash it off with some water.
  • Use the manufacturing directions as a guide to applying the vinyl patching compound into the crack. Remove air pockets from the mixture by tamping it. Also, in case you choose to “use patching mortar instead of vinyl patching compound, either mix it with bonding agent instead of water or coat the edges of the surface to be repaired with the bonding agent.”
  • Use a trowel to smooth the mixture out.
  • Let the patch set and smooth or brush it off so that it matches with the rest of the concrete surface.


Your foundation is one of the most important aspects of your home because it supports your entire house. Even if you don’t think of your foundation as your first floor, your house does. Both the structure and the air quality of your basement have an effect on that part of your home that you live and sleep in. Wood rot, cracks, mould, moisture, water and pests can all cause harmful damage to your living spaces and the people who occupy them. Most can be attributed to foundation problems.
