Is that a DIY job?

Given solid concrete floors, how do you drill down low enough into
the wall?

You can hire the equipment and chemical from tool hire shop. Two
holes per brick and bang plenty in.

If it's a cavity wall, the cavity may be full of cement/rubble etc.
You need to make a hole big enough to get your hand in and have a
look with a light and mirror. If it's full of crap you will have to
rake it all out.Â* The cavity should go well below the floor. (The
crap may be bridging the damp course.)

Not many here will see your post. This is a pleasant change from your
normally bigoted posts with no relevance to DIY
