Garage conversion

[Darrenr75]

Hi everyone

I would like to change my garage to a utility room, leaving about 25% at the end as tool storage.

My question is around the flooring - once I've installed the DPM, is there a minimum distance between that and the timber frame I'll need to install or can it go straight on top of the DPM?

Cheers,

Darren

Are you putting a screed on top of the DPM?

Hi Pred

I wasn't planning to, no. The garage has a very decent, level concrete base.

Cheers

I'm confused about how you're putting a DPM down, that normally gets covered with 4" of concrete, are we talking about the same 1200 gauge DPM?

So if I go DPM, then screed, can I place timber on top of that? Obviously this starts to raise the floor level somewhat.

My conservatory, a separate building about 10 years old, has a DPM and then concrete and then underlay and then laminate. Is this normal?
Cheers

Normal nowadays is, hardcore, 100mm half to dust, 10mm sand blinding, 1200 gauge DPM, 100mm thick sheets of polystyrene, 100mm concrete, 50mm screed, unless they have altered the building regs again.

Lay your DPM on the existing floor and put your timber joists straight onto it if you like.

Bear in mind that the existing floor may not be level

An easier way is to fix timber the to walls at the floor height, fix speedy hangers to this, and then drop the joist in. This avoids messing about levelling the joists

Its not normal if you are constructing a timber floor

Depends whether your a bricky or a chippy.

I thought he was going to use the concrete floor and assumed the timber frame was for stud partitioning.
