enriched all our lives with these worthy thoughts:

AFAIK, that *is* what the are, and if your concrete is indeed only 4"
wide, then it would almost certainly split.

4" *wide*??? I assumed that was an error and the OP meant 4"
*thick*. At 4" wide, it's doing well holding itself together!

In that case, I'd use frame fixings to fasten a timber batten
to the concrete and then fix the GH to the battens. If the frame
fixings are at, say 500mm centres, that should be adequate to anchor
the battens and the GH.

Probably shouldn't be replying as I don't really know what I'm talking about
but I happened to be flicking through a Screwfix catalogue at the weekend
(don't ask - very bored at someone's house) and they had several varieties
of screw-like fixings where they were promoting the fact that these gave a
sound fix into plaster and concrete *without* expanding - basically it
seemed they had a fine sharp thread that digs into concrete...after drilling
a hole of course.

Please forgive me if I've said something daft. Lunch is over so I will go
back to doing something I know about i.e. managing parks...
