With water still penetrating the basement, you'll have mold/moisture issues sooner than you think. Snot and I learned this the hard way after buying our place with a finished basement - Everdry really does have the method for ELIMINATING water problems in basements - any interior systems will still allow hydrostatic pressures to take their toll on the walls/footer - personally, I'd rather have a pro company do the work correctly and quickly, with everything warranted -- We have a big deck, stone walkway, and flowerbeds that they guarantee will be as they were.....but its up to you and your wallet - may be some DIY scenarios that would still allow you to seal it up on the outside?
