Laminate flooring over parquet

[DIYnewbie78]

Hi,am looking at laying laminate flooring over parquet flooring that has a concrete sub floor. What kind of underlay would I require? Would a DPM also be needed?

Just some background also,the parquet has been removed and screeded in certain sections due to plumbing and new pipework being laid.
I look forward to any advice.

Kind rgds.

The parquet flooring used to be stuck down with bitumen, which can act like a DPM, so do you know if the bitumen was removed in the screeded areas. As you're very likely uncertain over the concrete floor, it could be safest to fit an underlay with a built in DPM. Have a look at this sort of thing. http://www.underlay4u.co.uk/laminat...RJaREb0tHifCpW62yePlGgKGYEpijToCuqxoCv6Hw_wcB

Hi,many thanks for the prompt reply.
The parquet is stuck down with bitumen. Where some of the parquet was removed for the plumbing and laying of pipes ,so was the bitumen,this was then screeded over. Also forgot to mention ,the kitchen area has vinyl tiles,with concrete subfloor. Is it ok to laminate over these?

I suspected the bitumen would have been removed, hence my suggestion to use a DPM backed underlay. As the kitchen is vinyl tiles over concrete (which can be cold), I'd suggest a thermal underlay would be more sensible.
