Water leaking in from the highest part of a basement built on bedrock?

Steve Maxwell‘s article on “Keeping Basements Reliably Dry” was a classic when it first appeared in 2012.

One of the biggest headaches on dealing with moisture penetration into basements concerns houses built right on top of bedrock. This is because (a no brainer) water now starts to travel horizontally along the profile of the bedrock – and that can create all kinds of basement waterproofing issues.

Here is a recent comment about that…

I bought a house along the Madawaska River (Ontario). Yes, there is bedrock under the basement floor. Actually, one part of the basement is five blocks higher because of the bedrock. And now it is starting to leak through that raised area. Any suggestions?
