I'm using a dry area channel next to a wall as suggested in your article on damp proof courses. What is the minimum longitudinal fall to a gully?
but pure level is hard to achieve so 1:60 is advised
in old language this is an inch to every 5 feet,but what i normally do is use a level on each one and just have the bubble touching the line on the high side,too much fall looks naff
