I have an aged asphalt driveway that runs right alongside the house. The foundation wall is covered by some kind of very coarse stucco surface, I’m not really sure if you can still call it stucco. Anyway, it looks like this stucco once met the asphalt surface but some settling has occured and now there is a gap, both horizontally between the asphalt and the foundation wall, and vertically, between the stucco and the asphalt.
During some heavy rains I’m getting a small puddle in the basement coming from somewhere along this wall. After the first time I thought I might wait until spring to address it but it’s happened again. I’m looking for some kind of elastomeric sealant product to fill that gap and keep the water out.
The gap appears to be 1/2″ or less, just eyeballing. I thought about stuffing in some backer rod and a waterproof exterior caulk or sealant. Or a blacktop crack repair. There’s so many choices and they all do everything except one of the features you need. I also don’t have too many days of above 40 degree weather left.
Anyone have any products to recommend that I can apply in less than 50 degrees with freezing overnight?

your approach is a little like putting a new bilge pump in a boat cause the hull is leaking but, you can use driveway crack sealer, it comes in a caulking tube. Just warm in the house go out and caulk, warm in the house, go out and caulk, warm ...
So what's your approach, then? You wouldn't spend $20 on blacktop patch before spending thousands regrading and replacing a driveway?
no, I'ld spend it on repairing the foundation ..
And how much foundation repair can I get for $20? Last year I had some water come in another corner of the basement. I diverted a downspout further away from the house and the corner's been dry ever since. I guess that fix wouldn't meet your standards either, but that's the kind of thing I'm looking to do if it eliminates or puts off the need to excavate 7 feet all around my house.
