Default Floating wood floor.

Last year laid down a floating wood floor, now i have a problem with
it cupping in a couple of places.

The wood is soft pine T&G glued together and ronseal diamond hard
about 4 coats, looks good apart from the cupping and springy (bounce)
of the planks of wood when i stand on it in a couple of places.
The subfloor is concrete with a vapour barrior and underlay combined.
Their is a gap all way round the edges to allow for expansion.

I could remove the offending plank about 6 planks in from one edge and
glue and
re-varnish but i know this will show when i varnish it again
(overlap).
Could re sand the whole floor, but the diamond hard varnish is rock
hard and would take many hours, already tried this on a scrap piece of
wood.
I was toying with the idea of hiring a hilti nail gun and fire nails
through the wood and into the concrete, i have spoken to the hire
company and this can be done. Quite expensive to hire, nails and
cartridges are the biggest expensive.
I have seen that you can now buy concrete screws, thought of screwing
through the wood and into the concrete subfloor.

Has anyone got any suggestion what i should do.

Thanks.

Do teh same as mee, wait for winter and central heating to get it back
in shape :-0)

Alternatively, put heavy weights on. With luck it will 'conform' eventually.

Default Floating wood floor.

Tried the heavy weight, seems to work for about two days then starts
pushing up.

I agree the central heating will shrink the planks, i was amazed how
much they did shrink around the edges of the wall under the skirting
boards last winter. (did a proper job removed the skirting boards,
that wasnt easy but better looking).
I am tempted to remove the skirting to see if there is a gap around
the edges i know i had left some expansion, maybe not enough.
