Now that we know what causes foundation cracks let's talk about how to fix them. There are a few different ways you can go about this, but we will focus on two of the most popular foundation crack repair methods.
The 3-step Repair Procedure
In order to repair cracks from the outside, you will need to do the following:
Step 1: Dig the Surface Around the Crack
To begin, you will need to dig a trench around the perimeter of the crack. This will allow you to get to the root of the problem since you will be able to see the full extent of the damage.
You can use a mini-evacuator or a spade to do this.
Step 2: Seal the Crack
Once you have dug the trench, you will need to seal the crack. You can do this by using a concrete patching compound or epoxy.
If you are using a concrete patching compound, simply apply it to the crack and smooth it out with a putty knife.
If you are using epoxy, mix it according to the manufacturer's instructions and apply it to the crack with a putty knife.
Step 3: Apply a Protective Lining
First, apply primer to the area around the crack in this step. This will help the bonding agent to adhere properly.
Once the primer is dry, apply a protective lining(waterproofing membrane) over the bonding agent. This will help keep water from seeping into the crack and causing further damage.
