How to Fix Cracks in Concrete in Toronto

Cracks in the concrete of your Toronto home may seem insignificant at first, but they can quickly turn into a major problem. Fixing them promptly protects the structural integrity of your house.
Here, we’ll show you one of the most effective ways of repairing cracks in concrete.

Basic Fixes

First, be sure the crack is dry and scrub it clean with a wire brush. Remove dust and debris with your shop vacuum.
Second, place three-inch finishing nails into the crack 12 inches apart from each other. They’ll later be used to align the gap with your injection ports.
Next, scoop out equal amounts of two cans of epoxy crack sealer with separate sticks. Mix them on your scrap board with a putty knife until the mixture turns grey.
You now need to apply some sealer onto the base of an injection port, paying attention not to plug up the hole. Place the port on top of the nails in the crack and press it against the wall. Install the remaining ports the same way.
The next step is to apply a large batch of epoxy sealer to the crack with a 1 1/2-inch wide margin trowel or putty knife. Be sure that both sides of the gap have the same amount of sealer (approximately 1/8 inch thick).
You can now cover the flange of the ports using the crack sealer, but avoid covering the neck portion. Smooth out the mixture and feather the edges with your paintbrush dipped in a mineral spirit.
Place your LCR cartridge into your caulk gun and insert the epoxy inside the crack. Seal up the port, move on to the next one, and repeat the process with the remaining ports.
Lastly, let the epoxy rest for about five days and use a hacksaw to cut off the port necks.
