Foundation Wall Crack Repair - Basement Interior

I’m renovating a basement bathroom and recently took down the exterior wall which was drywall and tile against furring strips. I found a significant crack in the wall which extends from the base of the basement window to the floor. The crack is deep in some areas and also wide in other areas. We have had significant rain over the past week, but I do not see any indication of water (and it was raining and the ground was saturated as I removed the wall). However, some of the furring strips were rotted below the crack – the furring strips were probably there since 1965 though and looked to be untreated. This particular basement window is also under an over-hand which I’m certain helps to protect it from water.

With regards to repairing the crack, I know that I could trowel in hydraulic cement, especially where the crack is wide, but it would probably not get very deep. Does anyone recommend the foundation crack kits ? I saw a number of epoxy systems that look as though they can penetrate pretty deep into the crack. I would be interested in hearing any suggestions recommendations on how best to deal with this. I’m attaching a couple pictures.

Thanks in advance !

 

I've had a couple of basements (poured concrete) that developed cracks, small to moderate, and in every case the builder, or myself, used the same repair company that used injected epoxy.

Only one time did the water not stop but they came out and fixed.

It's a proven system!

 

Thank you Marq1 - I appreciate your help (again). Do you happen to recall the epoxy injection system that you used? I noticed there are a lot of them out there, not sure if one is better than the others.

 

I've been away from the industry too many years to make brand-name recommendations. Although sticking with a well-known product line, such as Sika or Adhesive Engineering, is likely to bring better results. And remember to use a low-modulus epoxy instead of high-modulus, as the former has an inherent amount of "give" as opposed to being brittle.

 

In our case it was a company that came out and used a pump to inject the urethane into the wall vs a DIY kit.

 

I did investigate the epoxy injection systems and I had a few people warn that because of the size of the crack, there was a good possibility that the epoxy might leak out. I purchased a masonry epoxy from PC Products but have not received it yet. It was purchased prior to reading Bridgeman's recommendation for a low-modulus epoxy, and i have confirmed that it is a high-modulus epoxy. I was not aware of the difference until I read the comment and started doing some reading. Since the foundation is over 50 years old; would that reduce the likelihood of further settling ? It sounds as though the primary reason for using the low-modulus epoxy is to have some elasticity in the event of movement or settling

Thanks again everyone
