How to Fix a Concrete Wall


Many structures, from homes to businesses to garages, have concrete walls. Time, harsh environmental conditions and accidents can damage these walls. A broken or damaged concrete wall could cause extensive damage on a structure's interior. It's not necessary to hire a contractor to fix the wall. Save time and money by mending the concrete wall with a few products available at most home improvement or hardware stores.

Things You'll Need

  • Chisel
  • Hammer
  • Wire brush
  • Cement adhesive
  • Paintbrush
  • Ready-mix concrete
  • Water
  • Bucket
  • Pointing trowel
  • Small stick
  • Tap the concrete with a chisel or hammer to widen the hole. This will help the new concrete adhere to the old concrete.

  • Clean the newly chiseled area with a wire brush. This will remove any dust or debris left behind. Do not brush too heavily--that will smooth out the newly roughened area, which will make it more difficult for the new concrete to bond to the older surface.

  • Apply a thin layer of cement adhesive to the area below the hole and around it as well.

  • Mix the ready-mix concrete and water according to the package directions in a small bucket. Apply the cement into the hole with a pointing trowel. Apply firm pressure to work the cement all the way into the cracks around the hole.

  • Rub the top layer of new cement gently with a small stick to roughen up the sides around the hole. This will help the new and old cement match better. Allow the patched area to dry for several hours.
