patio slope

[AndyBill]

hi,
how is the slope incorporated for patio slabs? is the type 1 sub base sloped or when the sand/cement screed layer is put down?

The slope should be incorperated into the sub base. Your bedding should always remain a consistant depth.

Fall is dependant on the paving used. For block paving or smooth slabs then between 1:80 and 1:60 For riven flags consider 1:60-1:50

More than one in 50 can begin to be noticable.
