Laying a solid wood floor on concrete

needadvicepls

Help, i need some advice pls. A friend of mine (carpenter by trade) is going to lay a solid wooden floor on concrete for me. He hasn't ever done one before and he as well as myself are unsure of the best method to use.

Should i :-

1. Just use a dpm and a self adhesive underlay? (I've heard Elastilon is good but can anybody recommend a cheaper option?)

2. Use a dpm, self adhesive underlay and also glue the tongue and groove boards together?

2. Use a dpm and or alternative underlay (like one i have previously used with laminate) and secret screw the boards together to completely float the floor?

Also is it ok with a standard doorway size to not have threshold joints? I'd like the floor to flow from the lounge into the hall.

Grateful for anybody's advice. Thanks.

The flooring manufacturer should be able to supply full details of the correct installation method for a concrete floor for their particular product

Liquid DPM to seal concrete and glue it down on top. Under no circumstances should underlay be used with solid wood flooring. But Olias is correct the manufacturer may have specific requirements rather than my general suggestions.

I disagree about underlay, I DIYed a solid oak floor which I layed as a floating floor (glued in the tongue and groove) over underlay and in the 6 years before I moved house I never had a problem with it and it was perfect!

You know how computer says no? Well men who fit for a living say no and manufacturers say no too! Solid can easily warp if its laid floating. Sounds like you were lucky or have a very stable environment in the house (temp, humidity etc). Now if it had been engineered that would be a different story of course - yes to underlay and yes to floating but OP said solid.
