Have a gap between my foundation wall and the concrete walk way beside my house. What would be best to fix this? It seems to be pretty deep.

Use the same product as you were looking at for the basement floor.

I took a close look at it today and it seems to go pretty deep on the one side. Still use caulking?

You can buy a foam rod in an assortment of sizes, you push that in and leave 1/4" for caulk. It's called cord, hence [cord and caulk]. The caulk that I have used stays flexable and is paintable.

Perfect! Thanks very much.

Plan on repeating the process in a year or two if just using "caulk." Far better to use either a 2-component rapid-cure silicone (NOT silicone caulk), or even a quality polyurethane. All with proper surface preparation, of course, and go with a minimum thickness of at least 3/8" above the foam backer rod, slightly recessed so not to get torn by snow shovels, etc.
