I'm certainly not a super expert, but it seems that the situation is bad with waterproofing. I think you should look up home waterproofing near me to fix this issue. For example, you can look at the widest range of their services to make sure that everything will work out. If they are willing to even install even a pump and a water check valve, trust my experience, they are really good guys. So get rid of doubts, and rather solve your problem.
