My parents' basement (in the hardest "sandrock") was arid dry for decades... built correctly. The 2011 'quake that damaged the Wash. Monument further breached the barrier... light moisture became an issue on mebbe 50' of walls in one corner.... basement became "musky". Cleaning (scraping) the bubbling walls (painted concrete blocks) and painting with Drylok a few times was futile. Did the complete "seal from the inside" walls with plastic type barrier, sealing a few cracks, and the trench lining the inside walls with holes drilled every few feet, sump, etc). Not one drop has entered that trench or the sump... ever. The basement is again bone dry with no issues .... a small dehumidifier does fine in the humid summer.
I'm happy .... the trench, sump, holes, etc. was $10K overkill in hindsight ... simply lining the concrete block walks with a barrier was sufficient. Been a few years now....
My .02 worth of opinion and $15K worth of experience, and after ME painting that dang corner with Drylok at least 5-6 coats ... over several years
.
Good luck!
Oh yeah .... mitigating the moisture breach from the exterior would have probably been 50K+ ... ea$y.
