Fix hole in brick from conduit run

[sands35]

My house has a brick vernier.

I had to take out a brick to run a gas line and electrical conduit.

Now I need to fix the hole.

My basic plan was to fill in the backside of the hole and the hole through the rum joist with expanding foam. Then squirt in some mortar using a plastic bag with the corner cut off. I have not done a lot of concrete and mortar work, but I would imagine that I need it to be somewhat pasty so it will not fall out.

Will I need to block up the mortar so it doesn't slump?

Has anybody done anything different?

Fill with foam as you say, but let the foam set up for a day as you want it to be done expanding before you fill in the hole.
When you do the grout you should put some dye in the mix so it will be close to brick color.
Depending on thickness of grout you can cover with tape to hold it flat and flush or use a board and a weight against it. Likely you will not need to but you can be prepared.

Another option, get another brick and cut a plug out of it. Insert plug with epoxy

OK - pretty basic.

Should I use grout or mortar or concrete (sorry not too sure if there is a difference in performance or just in consistency)?

I suppose that grout would end up with a smoother finish?

(BTW - the brick is painted white, so not worried about the color.)

Definitely use mortar Type S or N will be fine. If your using a piping bag the mortar can't be to dry or you'll pop the bag. Mix the mortar to a bit dryer to a slushy consistency. When your piping the mortar in don't try to fill the brick size whole at once or it will fall out, so let it dry up for 5 mins press it in and pipe the rest.

This works good, http://www.homedepot.com/p/Quikrete-20-lb-Fast-Set-Repair-Mortar-124120/100318469

We use it all the time for patching around pipes and A/C linesets.

If you've got a spare brick or even a piece of one you can crumble it to dye the mortar.

Why not just cut a brick to size and mortar it in to fill most of the gap and then just fill whats left with mortar?

Are you replacing a whole brick, half or just a small piece where the conduit came out ? Whole or half, I'd mortar in a brick. Small hole, fill it full of mortar.

A picture would probably help.
