potential floor problem

[townfanjon]

gents, could anybody help me with this ... I need to move an unvented cylinder, its on a first floor with all pipes comeing to it from under the floor. Its in a very expencive appartment and is only about 7 Years old. I pulled up a carpet today and found a timber floor covered with a blue coloured plastic laminate stuck to it. It must be glued down in massive sheets and there isnt a screw or nail anywhere, it looks a nightmere to get up. I just get the feeling the joists holding it all up wont be 6x2 timber joists. Anybody any ideas, thanks.

That sounds like chip board flooring i used to see go out of the timber yard i did some bits in.

there were 8" x 2" sheet as per normal chipboard sheets but had a green sheet bonded to them, they were designed ( I believe) so that floors could be put down inside the building before the roof when on as they were water proof, an attempt to combat the working at height rule i suspect!

They usually left on wagons packed with multi-web engineered joists and lots of tubs of glue, PU glue I believe, and this was lavished over everything as this added to the waterproof seal of the floor.

its prob not nailed or screws due to sound proof reasons.

Nope no nails!! nails is time and money!! just bonded with pu glue the entire length of the joists!!

If its a laminate, why not just cut a small section out (that wont be see - ah its covered in carpet anyway) and investigate as a preliminary part of the job?

thanks for the replys so far chaps, the 'laminate' ,is like the surface of a non-slip tile.
Its more what I will find underneath. As ADM says they might be the weird ply 'type' engineering joists.
I have to move some 22mm copper and they could make it difficult, (not been able to notch etc)

Bod . no pal, its in the posh part of Yorkshire ... Wetherby, LOL.( full of dirty Leeds fans)

Could you be on about the renovated mill development and new build apartments near Plover rd.
Sorry I cant remember the developments name but its in that area.

you could explain to the customer it needs a joiner to remove the floor and repair after that way you pass the buck

 

[Barry98]

If it's the ones I'm thinking of its fire retardant to stop the lot going up instantly

 

[townfanjon]

thanks again for all comments chaps, I think this may be getting a 'swerve' lol.
I have visions of me /joiner removing the boards and it writhing the joists to bits because they are glued. This type of floor is not designed to come up.

Can you not cut a trap either side of a joist or pair of joists then drill holes in the center of the joist web , so not to reduce any strength , some times you can get away with a 150 mm hole saw then once you moved any pipes put a batten under for support and screw the bit back in .

Be a concrete sub floor with insulated stools then 2*2 timber with chip glued to it. Bit of a mare. Do as joiners do with gas.... Bodge it up!
