I have a poured concrete patio about 20x8 ft that is up against the foundation wall. There is a gap about 3/4" wide where it meets the house. There was some kind of sealer in the gap made out of what appears to be a tar like product. The sealer has deteriorated over the years and we are getting a small leak in the basement. I would like to reseal this gap but I don't know which product to use. I was thinking of hydraulic cement but I am unsure if I need to use a flexible product to account for expansion/contraction. The gap is pretty deep so I could use backer rod and finish it off with flexible caulking of some type or I was thinking of using hydraulic cement but not filling the gap all the way and then finishing it off on top with a caulking. If I use a caulking what type should I buy?
DAP makes a self leveling cement crack filler that works great and is easy to get out of the tube. It runs about $8 a tube but I have had the best luck with it. I found it at home depot in the caulk section.

Since it's lawn on the other side,there's no need for expansion joint,if you think the leak is from the gap between the foundation and patio,fill the gap with what ever you feel will last the longest.
