It's a complex issue. Tell you my case happend a few years ago.
A few years ago my basement was flooding after a heavy rain in later winter. I discussed with professionals in HomeDepot and got many suggestions.
After dried, I opened the wood board wall, but didn't find any crack. The flooding reason should be there was too much water around the outside of a conner during the rain. The key point is to avoid that and to drain the rain water far away as quickly as possible. So I had a professional to fixed the leaking gutter. Then I changed the underground PVC pipe with quality ABS pipe as per recommendation. After that, the problem never happens again.
