Hello,
I'm about to lay my first patio.
The area is 48m2 (8m x 6m), and is enclosed on all four sides. I'll be using concrete slabs and full mortar bed.
For drainage I was planning on using a linear drain which will connect straight to an underground 110mm drain which goes directly in to the sewer.
Part of the reason for choosing a linear drain is to make things simpler for myself when laying the flags as I won't have to worry about crossfall (I'll be using a channel with built-in fall).
I have one question, though. Do you think just one linear drain at one end of the patio will be adequate? My concern is that an 8m run is quite long and might mean water is hanging about for too long. I was planning a 1:60 fall. Should I go steeper? Should I add a second linear drain at the other end and back fall to it? Am I over worrying things?
Thanks for your help.
