Hi All,
I'm replacing the concrete floor in my ground floor toilet. Where the soil pipe went through the old DPM there was just a hole cut in it, roughly the size of the pipe and that was it. Our local Building Control want a sealing collar installed that sticks to the new membrane and the existing soil pipe.
The collar can either be a bought preformed one or made from a spare piece of membrane. Can anyone advise me how to make the collar from a spare piece of membrane and or tell who make the preformed ones?
Kind regards.
