so you know, MOST-if not All basement walls were/are Only parged or damproofed when built and, were Not backfilled with peastone/gravel.. So, anyone, especially alot of these Inside Co`s who try `n tell you that Exterior Waterproofing won`t work etc is completely full of nonsense! Damproofing and backfilling w/same sit soil is a far cry from waterproofing `n backfilling w/all peastone.
Many,not all of these Inside Co`s do not want to or are Not capable of doing Exterior Waterproofing. This is why you/others will hear or get exterior waterproofing estimates that are out-of-sight,very high. And also why you are hearing various/different answers
Many salespeople have been told/trained one thing....that is to push/bs/mislead and sell sell sell the inside drain tile or baseboard systems w/sump and many also actually believe its what is best for you and that it somehow stops/prevents water from entering cracks `n other outside openings `n somehow stops/relieves lateral `n hydrostatic soil pressure,which does indeed cause basement walls to crack, leak, bow. I`ve got news for them...it doesn`t!
Don`t believe me? thats ok
Read following from OTHERS to help you understand what is best to help stop/prevent/lessen/relieve soil pressure and stop water from entering
Please read 6th paragraph...

questions 1) are sumps allowed? and 5) what if problem is not related to surface grading and water is leaking through foundation?

scroll to -Possible causes
...Hydrostatic pressure..."Rainwater seeps into soil and builds up pressure against your foundation walls. This hydrostatic pressure can exert tons of force on your foundation"
"Cracked and buckled walls- Hydrostatic pressure can press against your foundation walls, even buckling of the walls and flooding. Heavy wet soil continually presses against your foundation walls...."
to try `n answer your questions from afar...
...can you just waterproof the two-sides, the bowing walls? Yes
...can you just take care of walls from outside without waterproofing or do the two acts one is same? Well, you can do whatever you like, its your home. The two acts really should be done together because there is-are cracks on the Outside of bsmt wall(s) and not waterproofing the walls would be a complete mistake. Why would any company recommend not waterproofing a wall or any homeowner not want it waterproofed and only try `n brace it, pier it etc is a very big gamble, like i say, the wall is bowing in-has step/vertical/horizontal cracks etc where water/moisture enters into hollow-block,imo.....BIG mistake not waterproofing it.
We`ve seen quite a few homeowners who have hired certain companies to install helical piers and/or, want to use wall anchors and so on and Not waterproof and backfill w/gravel. This was a big mistake as more rain in coming months,year etc caused the ground/soil to continue to expand and contract, some also had tree roots that also helped cracked `n push basement walls in further. So walls did get worse/deteriorate and, they leaked.
They got worse and leaked due to Not waterproofing and leaving the same soil/roots against the outside of the basement walls which is what caused the problem is the first place!
