I've just pulled up the old laminate flooring and underlay to discover that the concrete floor beneath is very uneven with a few blown sections in the top screed. The floor is a bit of a hotchpotch but I can't see any Dpm. In the ideal world I should probably replace the entire slab or better still expose the original floor tiles that i can see down the edge of the slab. However I'm looking for a cheap solution that will just do the job, so presumably some kind of paint on Dpm then levelling compound?

level compound and dp underlay. could be simplest option.
What floor covering is going down? How old is the floor?
Ta for the replies so far...
The floor is probably approx 30yrs old (just guessing) and i'm going to be putting laminate ontop.

Nice one, what makes you think there is no dpm under the concrete?
Is the concrete smooth or rough?
You could put a liquid dpm onto the screed which is a good way to go but if the screed is rough then you might need to put a latex screed down 1st.

cheers,
Its mostly smooth, but there are a couple of small areas (30cm approx) where the surface screed has blown. i've pulled this up to expose rough concrete below.
The reason i don't think there's a dpm is that i cant see anything at the edges of the floor. Along one edge there is a 2inch gap, at the bottom of which appears to be the edge of the original floor tiles...no sign of plastic.

I've just spoken to a builder about levelling the floor off and he's doubtful how successful this would be as the floor is fairly uneven from one end to the other. He's suggested ripping up the concrete, digging out, making a new sub base then insulating and using weyroc boards to build what would essentially be a floating floor.
I know this would probably be a good job but i'm looking for a straightforward option....any thoughts?

I guess another solution might be to remove the concrete carefully and hope that the old tile floor that i think is underneath is reasonable nick and use this...but it could be an expensive gamble!?
