Easy Ways to Fix Foundation Cracks

Foundation cracks are not only an eyesore, but if left to widen, they can lessen the foundational strength of your home, as well as lower any resale values that it may have. Repairing these types of cracks is an easy process, and there are various different products on the market that will get the job done. To repair foundation cracks you can use products such as plugs, epoxy plastics, or concrete injection products. No matter which repair item you decide to use, the steps are the same in repairing the crack.

Tools and Materials You'll Need:

  • Masonry chisel
  • Hammer
  • Small concrete trowel
  • Wire brush
  • Bucket
  • Mixing stick
  • Water
  • Repair product of your choice

Step 1: Prepare the Concrete

In order to properly fix a foundation crack you must first prepare the concrete for bonding. Use the chisel, hammer, and wire brush to clear the edges and inside walls of all loose debris. You want to leave the bonding agent as solid of a foundation to set into as possible.

Step 2: Prepare the Repair Product

Follow the directions on the repair product that you have chosen and mix the product in the bucket. Estimate how much of the sealer you will need and only mix that amount, thus eliminating unnecessary waste. If you are not working outside, be sure to cover the area with a drop cloth or piece of plastic to protect the surrounding floor. Be sure to stir the mix thoroughly with the stirring stick. The bonding agent needs to be completely blended, which gives it the texture, drying capacity, and strength needed to make the repair long lasting.

Step 3: Apply the Product

Apply the product according to the directions given with the specific product that you have chosen. Always start at the top of the crack and work your way down. If you are using putty, which is usually recommended, be sure to work it all the way into the crack, and wipe off any excess amounts that may make the foundation walls uneven. If the crack is a large one that has been allowing water to seep into it, continue to work the material into the crack until the bonding agent begins to dry. This will allow the material to expand or contract as it dries, but also keeps the crack full of the bonding agent to ensure an even repair.

This type of repair is actually an easy project for the average homeowner, so only hire a concrete specialist when you need new concrete work done. The only problem that may be encountered is adding to much bonding agent into the crack, which will leave a jutting protrusion after it dries. Be sure to pay attention to detail, stay by the crack until it has mostly dried, and always wipe off any excess amounts of material. This will allow you prevent overuse of the bonding product, and will allow the foundation crack to be repaired in a professional, permanent manner. That is all there is to fixing a crack in your foundation. Whether it is on the outside, or the inside, of your home, the steps to repair it are the same.
