Can particle board be used as a subfloor. Please help


Hello all,
I am new here but I have a big problem (well I hope not).
I am renovating my home in new orleans however one of the contractors
used Particle board as a subfloor. Well, I had a few carpenters come by and tell me that this is wrong and well basically SCREWED UP!!

My question is, is that totally true? Could particle board be used as a subfloor for hardwood floors?

I know moisture is the problem so is there a sealer that could possibly be used?

Could a layer of plywood be added on top of it to "sure it up", as opposed to tearing out all of the particle board.

The whole downstairs is covered in this stuff and I am really hoping there is an alterior solution to this problem.

I am in New Orleans where humidity is very prevailent.

Thanks for your advice
-mio

Did you pay the contractor that put down the particle board?

particle board is not recommended for that use.

If it is literal, furniture-grade "particle-board", it should not have been installed in the manner you say it is.*
Standard Particle Board: http://en.wikipedia.org/wiki/Particle_board

Now, on the other hand, if it is an engineered T&G Flooring-Particle-Board (specifically made for flooring), that is different.
Example: http://www.thelaminexgroup.com.au/do...t_Flooring.pdf

Could it be something like Advantech Flooring?

Could it also be engineered OSB T&G Flooring?
LINK: http://www.lpcorp.com/subflooring/subflooring.aspx

At this point, you might want to do more investigating and find out what the material actually is.

* Standard furniture-grade particle-board is an acceptable floor underlayment material (Underlaymant - Material placed over the actual Floor Sheathing to build up thickenss/floor height).
Note: In areas prone to dampness or possible moisture (kitchens/baths) if standard, untreated, installed particle-boards receive moisture, they will easily absorb it and swell.
Moreover, Standard furniture-grade particle-board is NOT a structural material for Floor sheathing.

Thanks for the replies!
I believe it is regular particle board (it was bought at lowes)
but I will make sure it is not OSB. I have to make sure it was not
engineered also but honestly it looks like regular particle board...

Honestly, I was out of town so the guy was dealing with my wife
and I guess he pulled a fast one. But, I didn't know anybetter myself
so I don't blame her. The guy has done some other make up work to
compensate for these but I'm assuming the floors still need to be replaced....

The advice you got to do some investigating on the wood should be your first move. Find out what the stuff is first before thinking about replacement.

Ok, well as I said, it is regular particle board. Nothing engineered, nothing special. So I'm assuming this must come up? or, could I add 5/8 plywood on top of it and still be protected??
Thanks

There are dozens of types of "regular" partical board. Some suitable for hardwood and some not.

FYI too, all particle board is enigineered.

There should be a stamp on it somewhere with enough info for you to google

Interesting.. maybe there is hope afterall.

If not however, what type of subfloor is recommended for a good subfloor to place hardwood on top of.
would you recommend a 3/4 plywood? or something else?

Ok, I found out today that it is actually OSB.
However, I also noticed a leak in my roof today. The floor is pretty wet on the back end. Is there any hope left?
