Basement foundations should be insulated to minimize energy losses and should be protected from water infiltration. Even if a basement is not intended to be used as a finished space, it's best to assume that it may be finished in the future. That's why it's a good investment to upgrade from damp-proofing to a true waterproofing system when the basement is built. It's always cheaper to ...

External Insulation of existing basement foundation
by Andrei Sosnovsky

I'm planning on waterproofing of basement foundation walls and adding new weeping tile. I though it would a good idea to add rigid foam insulation since foundation walls are exposed anyway. What's a good way to protect and finish the above grade portion of rigid foam? After reading multiple articles I still can not seem to get a clear answer. Any ideas? Location - Toronto, Canada.
