Hi.
I live in a 2019 newbuild. Timber frame construction with Posi Joists and Caberdek upstairs flooring. I have a recessed shower cubicle and have noticed the shower pan (plastic/polystyrene) has cracked. I dismantled the shower cubicle and pulled up the failed pan (only siliconed around the edge). It appears Mr H Basher the plumber chucked a bit of plastic under the tray so it hasn't sat perfectly level, likewise there has obviously been a leak which has made the floor go moudy. The floor is sufficiently damaged and will need replacing.
My question is about cutting the Caberdek out. I can do this (I have a picture from first fix so know where the plumbing/cabling below is) but the stud walls forming the enclosure do not sit on joists and sit ontop of the Caberdek. I really don't want to remove the stud walls if I can help it. The recess has two joists running through it on 600mm centres. So if I remove the whole area of the recess, how do I support a piece of ply on the two unsupported edges?
Photo including one I've editted to show the Caberdek edges and joist locations.
