[Zeberdee]

Is there a way of fixing an OSB board or Ply Board to concrete??

Questions welcome but I'd like an answer to mine 1st.

Cheers

Thanks for the link, However its not really helped what I need to know.

Can you fix OSB/PLY Board to concrete? On top of roofing felt?

A mate has been asked to quote for a flat roof (he does the EPDM RUBBER) Its about 70 sq mts.....But half of the roof is a concrete roof because it was an old bank vault. The concrete bit has been felted and is in pretty good condition but they want it doing with the rest of the roof which is leaking (also felted) To get a nice job requires some nice flat surface for the EPDM to adhere to I.E. OSB/PLY. Would a Hilti gun fasten the boards??

you should be able to using screw n plugs but dont be short on the amount.
you could first fix firing strips and create a healthy fall then fix to to strips

We did a rubber roof to a huge concrete shed last year (first one we ever did). We put a damp course on the roof, screwed 2x1 beams down with plugless frame fixings countersunk into the beams and then screwed the osb to the beams. As Dave mentioned if there is no fall get some strips made up.

Oh and make sure you have 2 spare drills and 37,000 spare drill bits

Just re-read your second post. As long as the felt is smooth and flat then yes you could board over it but the proper way would be to take the felt off and board down onto the flat concrete.

Let me know what your mate quotes you as we do a lot of EPDM jobs in Brum.
