I'm willing to bet that's not what the OP is thinking of
however.

Yes - I need something a little stronger, and bolts should definitely
be involved, rather than just wedging the posts in.

I've seen things that have a galvanised socket or "U" bracket for the post to sit in which is welded to a galvanised rod that is then
set into theconcretewhich maintains free drainage of water away
from the bottom of the post and keeps it clear of any
groundwater. I keeps the timber relatively dry and I guess
prevents any rot. Dunno what they're called though. ;-(

I've seen these too, where the bottom of the post is above the top of
the concrete, sometimes even with a gap, e.g.:

I'd prefer holders/brackets, though, where the concrete holds part of
the thing in a downwards direction rather than just squeezing it from
the sides.

Those Powrfab things might be the ticket. I may be wrong, but I think
they are made for the purpose I need, rather than for hanging joists?

Any idea where I might get them (or something similar) in the UK??
