Replacing a chipboard floor

Post by sastek » Thu Jun 14, 2018 12:08 pm

Hi folks, because of a leaking pipe, I have to replace the chipboard flooring in my hallway. The current system is 25mm battons nailed to the concrete with white polystyrene insulation between them, then the chipboard is screwed on top. Everything is wet so it all has to come out.

I wanted to ask if it is OK to just replace everything as it was, or if there is a better solution or regulated way to do it? I can't change the height because the floor has to meet up with the rest of the hallway. Also, should I lay a plastic damp proof sheet on the concrete?

Replace with the same thickness. If you go the chipboard route I'd recommend something like Egger P5 T&G chipboard with the tongues glued. P5 is moisture resistant. Alternatively same thickness hardwood plywood could be used in which case I'd suggest that you groove the edges and glue-in a loose tongue (1/4in or 6mm plywood). Battens should be tanalised (treated)
