How To Fix Foundation Cracks In Your Basement
There are two types of foundation cracks that could be in your basement: structural and non-structural (also called waterproofing cracks). Structural cracks require more work than non-structural cracks but don’t worry. Professionals have solutions for all of them.
Structural Foundation Crack Repair Methods
A structural foundation crack is a crack that poses a threat to your home’s structural integrity. They can be the result of existing issues or lead to larger issues themselves. Cracks could be caused by walls that are bowing, sheering, or leaning.
Non-structural Foundation Crack Repair Methods
A non-structural foundation crack is a crack that does not pose a threat to your home’s structural integrity. Experts call these “waterproofing” cracks because even though they aren’t a structural problem, they can still allow water to seep into your basement.

1.Diagnose The Crack In Your Foundation
First, you’ll want to diagnose your foundation crack, as it may be more beneficial to hire a professional rather than trying to achieve it yourself. Foundation cracks come in all different types of shapes, sizes, and dangers. Most of the time, they appear within the first year of being constructed, near corners and windows, etc.
2.Prepare The Crack For Repair
After reading the above, the option between hiring a professional and doing it yourself should be narrowed down. To summarize, as a DIYer, you should only be considering this foundation repair method if you have a vertical crack that is 1/8” or smaller.
3.Use Nails To Align Injection Ports
Now, you’ll want to tap some nails into where you want to place the injection ports. You should use 10D finishing nails and space them roughly 12 inches apart as a rule of thumb. This is to ensure an even mixture of epoxy when you inject it later on.
4.Formulate The Epoxy Sealer
We’ll use the Polygem Liquid concrete Repair Kit as an example but remember alternative brands may be different. However, you’ll receive two epoxy crack sealers labelled “A” and “B” with the kit.
5.Attach Injection Ports To Nails
Where you tapped in the 10D finishing nails earlier for the injection ports, you can now apply them. With the epoxy sealer, you mixed, place a small load onto the bottom of the injection ports to allow them to seal with the foundation.
6.Spread The Epoxy Mixture Along The Crack
Now you’ve achieved the above, it’s time to cover the crack and the base of the injection ports with the epoxy sealer you mixed together. When applying, be sure not to overuse or underuse the mixture.
7.Inject The Epoxy In The Injection Ports
Once you’ve spread the mixture equally across the crack by following the above guidance, then you’ll want to wait around 6 to 10 hours to allow it to cure. Once it feels dry, you can then begin using the LCR epoxy, which looks like a silicone tube in the kit.
