help for a huge 'deck'

[aturner]

Hi there,

I want to build a 100m2 rooftop 'deck' for a kids sports area, complete with side/privacy walls. Can anyone recommend the best substrate to support instant turf/all weather material? I wondered about yellow/red tongue but a BGC cement board might be best?

Any builders in Melbourne who want a decent $50-100K project?

thanks
Ashley

It depends on your subfloor layout , but i would say the best substrate if not weather proof would be 16mm compressed sheet otherwise red tounge ply woud be fine. Best of luck with the build
