Hi,

I really need help with my renovation. I need to start putting up the ground floor stud walls. At the moment I have the sub floor, not up to finished floor, I need to put down 100mm celotex wet u/floor heating and flow screed but I need to put the walls up first so I dont nail through pipes after the floor is finished. What can I build the wall off?

1:- Build one course of block 150mm heigh
2:- Build two courses of brick 1500mm heigh
3:- Make a temporary support underneath the walls I am building out of wood then remove the support when the wall is complete then the flow screed will seep under the wall for a fix

Does anyone out there know what people do in these situations?

lay 3x2 tanalised timber in floscreed, when its set solid you can nail your stud to it.

How do you mean. I really want to put the walls up first not after the screed is down. Do you think building a small wall 150mm in height is not a good idea?

ok

Really want to put the walls up first is laying a small wall not a good idea then. How do people do this in these cases?

you asked for advice,and I am giving you advice on what I do or have done in the past,You say you want to build a 150mm wall first?? we always lay the floor first before building the internal walls.Laying timbers in the floor will eliminate any chance of nailing through pipework and give you a solid base to work off.

Thanks for the reply, sorry if I offended you. so to clarify do I put the tanilised timber straight on top of the insulation or put it on top of the screed as its being layed?

[welsh brickie]

lay it in the screed as its being laid when its set you can fix to it

Hi

The method I used for my barn
was build off the "sub floor" using 4" celon blocks (plasterboard and skim)
for non load bearing walls, 1200 gauge polythene, 100mm celotex, very thin layer of polythene stapled and taped to seal against wall, lay exspansion strip around perineter, lay underfloor heating pipes and then liquid floor screed.

Bye

Another solution is to fix two layers of plasterboard to each side of the studwork. Dont forget to stagger the positions of sockets and switches on dividing walls
