Drains too high - Creating fall for block paving

[AndiForest]

Am I thinking in the most logical way??
Having just taken up a concrete driveway that was far too high for the damp course, I find that some of the drains are now too close to the surface to allow a drop along the length of the drive when reducing to formation level, without significant work on the depth of the drains. As the driveway that runs along the length of the house is only length 15 metres x 3 metres wide , I plan to slope the drive away from the house and run either dished channel or linear channel along the length of the drive opposite the house. This can then either link to the existing drains or a soakaway whichever is advisable when clear of the house. I know that this may seem the obvious solution; however being a novice I need some clarification of good practice in such circumstances.
I can provide pics via email if that would be of help to anyone reading this.
What an absolutely brilliant web site.

it looks to me that the dpc is the thick mortar band

what about a channel drain 150mm below the dpc along the house flowing into the the gully with the sink pipe

and the drive will slope in to the house

what are you laying? (rtfq) block paving

Cheers Andy for posting pics.

Yes block paving is planned
My thoughts were to slope away from the house because the drain in the pic is close to surface and would mean less hassle in lowering the pipe in view. I was thinking of doing exactly your suggestion but sloping away from the house and running the channel along the fence. As the main drive by the car is very flat I will have to slope half the drive towards the house. My thoughts were to run the channel across the drive somewhere near the corner of the house and join to a new soakaway. Drains here are FW only with rain water running to soakaway at rear of house. Not sure I would comply to Building Regs if rain water was directed to the FW system.

Hope that makes sense.

Cheers for advice so far

as you existing drainage is plastic, it shouldnt be so difficult to alter. By looks of it you are going to have to dig down some more anyway to have finished level 150mm below dpc see main site for blockpaving subbase prep
