Youre putting down a vapour barrier - why would you want two.
Belt and braces? I don't know - I was considering the joints, small as
they are.
Truth be told, having read up on laying engineered wood - I might just as
well put polythene DPM over the top under the wood - that costs
practically nothing and does no harm, on the offchance that any vapour
does leak through.
The one
issue I see is picking a glue for under the marmox that will be ok
permanently damp.
That's OK - had it on good authority that plain old cement based tile
adhesive (the grey sort you mix from powder) will be fine, damp.

The marmox should prevent condensation, which may have been the original
problem
I hadn't thought of it that way - but that room was never heated much and
the floor never gets higher than 15C - the earth base temperature under the
slab is around 8-10C by quick and dirty measurement. The floor covering has
been down a good 10 years too.
It's not like the slab is actually soaking wet - so it seems that it's more
a case of vapour coming through, getting trapped and presumably liquifying
as you suggest.
Yep - all things said and done, Marmox (or an identical product - there are
a few) is clearly the best thing for this house, with the least risk of
going wrong.
Thanks!

I have a tiled solid floor, and you can see by the darker colour on the
grout lines in certain places that there is always a degree of
condensation in the winter.
