Hi, guys.
I know there’re several topics already about this, but I still can’t get my head around it!
I’ve seen several drainage channels (threshold drain/threshold interceptor/step drain/brick slot drain) which allow for a level threshold between inside floor and patio to comply with Part M of building regs.
If we were to have a level threshold patio, installing one of these where the doors are (we’ve got French doors and bifolds) what do we do with the adjacent areas of exposed brickwork where the patio will be level with (or at least less than 75mm below) DPC?
I had thought that I could have threshold drains where the doors are and French drain/gravelled channel in the other areas, but that wouldn’t really work because I can’t see how there would be a continuous flow between them all. Unless I’m missing something??
Many thanks
