    What suitable mechanic fixings should I use to fix osb3 sheet to a concrete floor. Cant glue it as there will be a dpm sheet on top of the floor.

    Thanks

    Any type will do as in so far as fixing the board, but what about keeping it damp proof??? bit pointless fitting a DPM if your going to make holes in it.

    I know! :? But this is what OSB manufacturer recommended. I couldn't figure that out myself. The only solution I could think of is predrill the holes then fill them with liquid Damp proof. Any other suggestions?

    cheers

    Treat it as a floating floor, use T&G OSB 3 and glue all the joints.

    I only just realised the concrete has a dampproof sheet underneath so I guess it does not need one on the top. The concrete is only 100mm deep and it has been curing for three months so I should be ok to mechanically fix the boards onto the floor without another Damp proof sheet.
