If it helps; my inside is completely drylok'ed (previous owner) and I had drain tile installed by basement systems. My basement is still a never ending battle. I'm running two dehumidifiers 24/7, just to keep humidity ~60%
The water will eventually push right through; the drylok will make the basement look nice long enough to sell it (sigh).
IMO; based on my horrible experience; feedback here; books from the library; Holmes on Homes, This Old House, and other internet research, waterproofing has to happen on the outside with a proper drain at the base of the foundation (sitting on footing or next to it; I'm still trying to figure that one out); mastic tar; then felt; then mastic tar; then dimpled membrane. Run the drain to your sump or away from your property.
I am not in the exact situation; I have a detached garage and a walk-in. But my property is southern sloped and eastern sloped.
Whatever solution you choose; please share your results!
