    Hi Everyone,

    I house built in 1965 which has a bitumen DPM. It has a few damaged areas that need repairing where the concrete substrate is showing due to impact damage at some point and I'm not in a position to rip up the whole thing as most of it is fine.

    Its the same stuff as shown in this post: https://community.screwfix.com/threads/old-bitumen-dpm.182464/

    I'm planning on laying an engineered wood floor over it once it's been leveled and I'm concerned about moisture affecting the leveling compound and new flooring where the DPM is currently broken.

    Can anyone suggest the best way to repair this type of DPM?

    Easy don’t, make good the damage with sharp sand/cement and lay a 1200 gauge DPM over the whole floor ;)

    Thanks, I think I'll keep it simple to go with the full DPM over the floor as you suggest :)
