Hi all,
I am looking to pave my small front garden with slate slabs and want to get the drainage right. Currently, there is a drainpipe which ends approx 20cms from the ground next the front door into a channel formed into the concrete base. This runs approx 3m adjacent to the path emptying through a missing half brick in the wall. Its the same all the way up the street. (Picture attached)
Before laying the paving, I want to put this right; I don't want discolouring on the paving I am about to lay and down want water bouncing back against the house. I plan on extending the downspout into a right angle beneath ground. It will still discharge through the missing brick but I plan on installing a grid (hopper type) next to the wall for surface run off.
What is the best way to do this? Can I literally put more 67mm drain pipe in or should it go into soil pipe as it is beneath the surface? If the latter, any ideas on a reducing fitting? Also, any ideas on the best way to install it - as in should a use anything to shield the pipe? Concrete it in? Paving will be going on top of it, is this a concern on how deep it should be?
Cheers
Andy
