I ran a pipe through the foundation wall and need to seal around it. What is the best method, I read Sikaflex but not sure what exact type. Its only about 1′ below grade, and I dug a hole under it and put gravel below it so I don’t think I will be a problem but just want to be sure.
Thanks.

I've had good luck
using backer rod stuffed in the hole around the pipe-maybe a 1/2" in from the face of the foundation. Then I've used whatever brand of Urethane caulk I had handy-usually a Tremco product, but Sika makes good quality too.
Same thing on the inside-though I might try to get a bit nicer finish by running tape around the hole and the pipe-caulk and tool, peel the tape off for a nice crisp edge. Use backerrod here also.
