Brick base for aluminium GH.. what should I lay on top of the brick?
I have bought a second hand GH and have just had a dwarf brick wall built onto which I intend to set the gh. It was originally on a similar dwarf wall with a timber frame laid on top of the bricks. Is this a good option or will wood rot? Should I use coping instead? Then.. how do I fix coping/wood to brick... should I drill with extra long screws and use rawl plugs? If anyone has any proper technical terms so I can go to B&Q and get the proper bits and pieces I'd be grateful!
