Overlaying woodblock

Ive had a tender through, for 3x classrooms in a school.
1x science lab in poly and 2x classrooms in carpet tile.
There are some site photos also, and all three rooms have woodblock floor, which they tell me are all well fixed, and they want to fit over the top.
Ive never fitted over woodblock before. Could 9mm ply be fitted over the top, fixed into the slab, then a coat of fibre ?
Could carpet tile go straight over ?

Or is it all up, grind & start again. As usual, budget is a problem !

 

Personally, i'd take it up,what is solid now may not be after you change the conditions by covering it up. Reclamation yards sell that stuff for over £30m2 ,so if most of it comes ok,you might be able to get some money back for it,if not, get yourself a log burner

 

Yeah probably a take up and sell on. Normally don’t have the height to go over the top of it?
No way polyflor can go over it. Carpet tile would depend on the manufacturer but I wouldn’t trust it

 

Take them up, don't fit on top

 

Ok, so general consensus is get it up.
What about the gooiee mess underneath. Grind/Na what`s everyone's thoughts

 

Depends on what it's been stuck with, if it's an oldish floor then it could be bitumen, which should be hard and fairly easy to sand off, just a bit smelly

 

Wakol over it and level
Speak to Duncan at Wakol

 

Have you got a contact number mate ? Can message me if you like.
Cheers

 

Are they on the ground floor ?

 

Yep, ground floor

 

Massive risk then mate. The woodblocks could blow as they won’t be breathing anymore

 

Did you speak to Duncan?

 

I didn`t mate no.
The contractor owes me just over 30k and apparently has no money.

 

Hearing alot of this the last few months down here to from some of the lads I bump into down the counter who do the big commercial stuff.

 

So, still no payment. They have now promised to pay next week.
Won`t be doing any more for them either way, so thanks to everyone for the input on this.
