Easy Repair for Cracks in Concrete

It's inevitable and normal that a concrete slab will eventually develop some cracks. 

Luckily, it's an easy fix (and an important one to prevent further damage from water seeping in). 

You'll need a few supplies before you get started:

Step-by-Step Instructions:

  1. Remove any movable debris in the crack. Use a crowbar for larger chunks and a broom/blower for the smaller stuff.
  2. If the crack is larger than 1 inch wide and 2 inches deep, you’ll need to use a backer rod. The idea is to take up some of the space so that the concrete mix will be able to set.
  3. Mix your concrete patching. Only mix what you can use in 15- 20 minutes. Follow the instructions on the package, and be sure not to mix too fast as it can cause air bubbles and will affect how well it seals.
  4. Use your putty knife to spread the mix into the crack. Make sure to use a fair amount of pressure to force the mix in all of the corners.
  5. Allow to dry at least 24 hours before any weight is applied.

Finally, for your viewing pleasure, here's a video of me repairing a concrete crack:

Good luck!
