Hi All

Wondering if anyone can give me tips with a small project.


Its only 12" high and you say the ground slopes away at the rear so its not
actually retaining much.

I would be tempted to dig a trench behind it, build you new skin behind the
existing one and then fill with concrete using the existing brick work as
the facing.

If you want higher seating you can always raise it up using timber which is
much nicer to sit on than concrete blocks.

While you are digging the trench put some soakaways in to stop the grass
being mud.
