A floating floor over a good, dry and solid concrete or stone floor,
is usually
made up of felt underlay and top layers of either interlocked
chipboard or
laminate, or even both if more weight is required. Do you mean a
sub-floor to
cover an old concrete or stone base, or is it actually a floating
floor for
sound / noise deafening?


it's over an uneven concrete floor, so the underlay method won't work,
that's why I'm gong to screw down batons to level it out and put the
weiroc on top. Also it's a play room so figured it's better to fall over
on chipboard than concrete, floor covering will be lino.
