oops! we were having an overhead sewer installed and decided we didn't like our exit location for the pipe that penetrates our basement foundation wall. Trouble is, if I tell them to change it, I'm left with a 6" dia. hole in my foundation!!

Anyone have any suggestions as to how I could seal that? Do I just use a concrete adhesive and then trowel in new conrete?

also, can this hole ever be "waterproof"???

thanks

Hello,
I would use Plastic type cement, put in some wire mess and put on a water repellant.

You may also consider using eppoxy. Though a 6" hole will probably not become a structural problem water penetration may so you need a good seal-good luck
