Waterproofing is done outside with gutters, downspout extensions and grading and/or by digging out the wall to the foundation and applying the ‘proofing’ material on the outside of the structure. You are talking about methods of trying to stop the water when it’s already 99% of the way inside. Concrete repair Ottawa is highly expert in these types of jobs.
If working outside is not for you, a water mitigation system might be the next thing you should research.
