I have already have all the materials. I am putting a DPM down first.

Thanks Nick, might be a bit late for the concrete as I have already ordered all the materials. I’m putting 20mm x 1000mm x 1000mm rubber gym floor tiles on top of the T&G flooring. Haven’t ordered the tiles yet, so could go to 30mm

Hi, im about to start converting my garage into a gym. The walls are already insulated and plasterboard to the same spec at the rest of the house. The floor is concrete. I plan on creating a timber frame floor 100mm in depth using 2x4 with 100mm PIR in the cavities. 22mm caber deck T&G on top of the frame. I have read that the new floor frame should be 10mm away from the existing garage walls and 10mm away from the bottom of the plasterboard. I did plan on putting the new floor underneath the existing plasterboard, however that would mean trimming the bottom of the plasterboard and it will make it more awkward fitting the T&G boards. My question is should the frame be 10mm horizontally away from the existing wall (blocks) or could it be 10mm away from the plasterboard. Thanks in advance for any assistance.

I plan to convert an attached 6*6M garage into a gym, Iwill use free weights and a max loaded 600kG rack. The garage floor is concrete, I would like to insulate the floor and bring it up the the house floor level, which means I have around 100mm for insulation. What floor make up would the group suggest? I was wondering if a floating floor would be possible, however as room will be used as gym, this might not be possible. In that case was thinking 100*47mm treated timber joists on top of the concrete, at 400 or 600mm centers. I plan to use 20mm rubber mats as the floor. What would you reccomend below the mats, Plywood or T&G circular board and what thickness? Thank you in advance for any help
