2-part concrete help

Hello all you extremely helpful folks. First- I need to address vertical gaps in a foundation between the main house and an obviously-poured later/separately entryway foundation. I'm assuming this is simply from years (approx. 50) of settling, but the homeowner would like them sealed. Any suggestions? Expanding (not triple!) foam? Flexible caulk? Gaps are, at the most, 1" wide, and run from the ground up to the first course of asbestos siding.
Secondly, I have to repair a variety of holes, none more than 1-2" deep in previously painted concrete steps which are well-pitted/weathered. I've read much of the info out there (vinyl concrete material, basic mortar mix, etc.) but I'd like anyone who's had to deal with similar's input. Thanks for all the help!

Gap between foundations:

Definitely not foam......bugs will eat through foam

The gap seems a bit wide for caulk. besides,,,most caulks will shrink a bit.

I would fill it with a "concrete type" product.

There is something available from Rinker concrete called something like nu-cote which they use for resurfacing.

you can't use concrete since it has aggregrate that is too big for your gap.

You don't need a bonding agent for the gap since the product has the properties.

The nu-cote will work for the steps as well, although it dries to a light color grey but a little coloring before or paint after will work..

Good Luck
