Repairing brickwork around pipes

[wbmkk]

What is the best way to deal up the holes around two waste pipes which go out through the wall. Luckily thes are at the back of the housei o

I thought about bricks,or rather bits of brick but with both skins to repair I thought about the expanding foam stuff. Is that any good and are all foams pretty much the same. Externally could I cut the foam when it gardens, maybe fill it with filler,then paint with step paint to.help in blend in,

Your ideas would be appreciatedi

Foam is ideal. Only significant difference is that some cans are usable in all directions ( upside-down etc ) and some only upright. This is indicated on the can.
