damp walls in proposed kitchen

[AMc]

Most over the counter units I've seen have 2 screw fixings which I wouldn't trust fixed directly into thermalite block. By fixing battens then ply to the battens and then plasterboard then the units to the ply through the plasterboard you spread the weight of those two original fixings across a much wider area.

Each to their own, but as Worms confirms above, I've never found it necessary to to do more than pop in a short screw or two, in order to keep floor-standing units in place. As to the advisability of screwing into Thermalite blocks, surely this depends on what fixings you use.

Obviously the final decision is entirely up to ragingbull. In response to his request for ideas, I can only explain what I would do.

Perhaps I'm being obtuse ?!?-
Personally, I wouldn't hang wall cupboards, the ones that go OVER the counter from 2 screws fixed into thermalite concrete blocks.
There is no need to worry about base units, the ones that stand on the floor under the counter

No, it's me.

I interpreted "over the counter" to mean kitchen units that you buy "off the shelf" at the big DIY sheds.

:roll:

Of course I wouldn't hang wall cupboards directly on Thermalite blocks.

I'm glad that little misunderstanding has been cleared up; I had also misinterpreted which type of cupboard units were being discussed and did think AMc was being a bit over-cautious. It all makes perfect sense now.

The floor units will be ok without fixing to the wall as you say as the oak worktop is extremely heavy and I might be able to ease the units off the wall a bit, I'll just have to see how much overhang there is on the worktop. I think I confused everyone before. I was just thinking that I may need to protect the base units from the wall with them fitting flush. The over head units will be fixed into brick so they will be quite secure.
Thanks for all your comments guys its really interesting to hear everyones views.

Glad we all undestood each other in the end. With the base units I would try and create an air gap behind them but as long as you can get the run straight and scribe the wall/worksurface to suit the oddities in the wall then I wouldn't bother lining with anything.
