Can't argue with that ..Â* but it is now 40 yr old chipboard

Mine is 44 years old, and apart from slight sagging between the
18inch-spaced joists, is fine.

The only place where a hole had been made was where a
'plumber' made an access hole to fix an air lock in the
28 mm gravity feed to the tank. Looks like he used a club
hammer to smash a hole and then propped up the shattered
bits with a couple of lengths of 2x1 and put the carpet back down.


Did the repair with 18mm chipboard .. put a layer of 1mm foam underlay
over depressed sections before laying new carpet underlay.

Found the 2 broken boards had a reason instead of the T&G join (board
edge being on centre lie of joist it was about 3 mm off the edge of
joist - so unsupported. Failed at those points.
