I need to repair ( fill ) a hole in my basement wall. It is about
6 inches in diameter and is the result of having to replace the water
line coming into the house. What is the best material to use and the
procedure? All I can find on a Google search is repairing cracks.
This is much too large for those procedures.

Assuming your problem hole is below frost line and the outside of the
hole is dirt, you need to immobilize the dirt to permit cleaning the
hole for the repair. That may be nearly impossible to do, so consider
exposing both sides, repairing, then backfilling. When the hole can be
hosed off clean, then simply troweling in a stiiff batch of Quickrete
should work fine. The contractor doing the water line work should have
done this without even asking. Did he take any other shortcuts? HTH

remove all lose material, mix cement on dry side, spray water lightly
in cavity, for good adhesion then. pack with cement.

If the cavity is large do it a little at a time........

Concrete has gravel, if that will be too rough regular patching
compound is fine.

Carefully chip a brick into the right shape and mortar it in place. A
hole that big needs something solid to take up the space. I've done
that using a mortar mix with some extra portland cement to make it set
up a little harder.

But, I agree with Joe - fix the hole on the other side as well.

This repair really should be done on the outside. If the existing
hole is dirty, it would be best to chip the hole larger until you
have fresh concrete around the interior of the hole. It can and
should be jagged, Install a form board of some type on the inside
face - nail it, screw it, or push on it with a board so that it
cannot fall or bulge.

Mix equal parts of portland and sand, add only enough water to
hint at changing the color. This mixture needs to be extremely
dry. It should barely form a "snowball" when you squeeze it in
your hand. Pack a heavy layer into the hole. Use a hammer and
stick like a 1x2 about 10" long and begin to drive the drypack
into the hole. Once that layer is well driven in, add some more
and repeat until the hole is filled. Once full, apply a heavy
layer of plastic roof cement or equal to the outside concrete
larger than the hole you have filled. Reinforce the roof cement
with mesh, protect with a bit of tar paper, beaver board, or equal
and backfill. This can be done as soon as you have filled the
hole. You should be able to pull the interior form immediately,
but prudence might leave it on for a day or two.

Before doing this, I'd wrap the pipe with foam pipe insulation. It allows a
bit for expansion and vibration that can cause a problem five or ten years
from now.
