How To Fix a Foundation Crack

Feb 20, 2023

Urethane Resin Method

Urethane resin is a type of material that is often used for repairing foundation cracks. This material is a popular choice among homeowners and contractors because it is durable, flexible, and resistant to water and other types of damage. If you have a foundation crack that needs to be repaired, here is a step-by-step guide on how to use urethane resin for the job:

Step 1: Clean the crack

The first step in repairing a foundation crack with urethane resin is to clean the crack thoroughly. Use a wire brush or a chisel to remove any loose debris or concrete fragments from the crack. Once you have cleaned the crack, use a vacuum cleaner to remove any remaining debris or dust.

Step 2: Install injection ports

Next, install injection ports along the length of the crack. Injection ports are small plastic tubes that are inserted into the crack to allow the resin to be injected into the crack. Apply a small amount of epoxy or urethane adhesive to the surface of each injection port and press them firmly into the crack.

Step 3: Mix the urethane resin

Mix the urethane resin according to the manufacturer’s instructions. Urethane resin typically comes in two parts: a resin and a hardener. Mix the two parts together thoroughly until the mixture is completely homogenous.

Step 4: Inject the urethane resin

Using a caulking gun, inject the urethane resin into each injection port, starting at the lowest point of the crack and working upward. Inject the resin slowly and steadily, making sure that the crack is completely filled with the resin. Continue injecting the resin until it starts to ooze out of the next injection port.

Step 5: Seal the crack

After the crack has been filled with urethane resin, remove the injection ports and seal the crack with an epoxy or urethane sealant. The sealant will help to prevent water from entering the crack and causing further damage to the foundation.

Step 6: Allow the resin to cure

Allow the urethane resin to cure for the recommended amount of time, which is usually around 24 hours. Once the resin has cured, the crack should be completely repaired.

In conclusion, urethane resin is a highly effective material for repairing foundation cracks. By following the steps outlined above, you can use urethane resin to repair foundation cracks quickly and easily.
