Hello,

I have a brickwork driveway and a brickwork step leading to the front
door. My problem is that the bricks around the edge of the step have
all worked loose so that if you step on it you could easily slip off
the step and send the whole edge of the step on top of your foot.

No problem, I thought. I'll just re-mortar the bricks and set them
back in the step. But when I stripped the bricks away, I noticed that
underneath was about 1cm of SAND, plus some hardcore stuff under the
bricks themselves. No wonder the bricks came loose. My question is
should I be using sand or mortar stuff? Any particular brands anyone
would recommend?

Many thanks for any assistance,

Stephen Butler
