i've bought some aco drainage channels to go infront of my workshop as i'm in the process of block paving it. The drive actually slopes away from the workshop but i'd rather have something there in case of heavy rain.
However the issue i have is the drive is encased either side by large dry stone walls with fairly deep footings. On the one side is the next door neighbours and trying to puch through the wall footings on the other side will be a right pain in the ass.
Due the fact i'm not anticipating huge amonts of water through the channels what are my options regarding a soakaway?
I've got a sump unit for the aco channel which i will fit in the corner. Could i simply perforate the end cap of it(comes attached as standard) and allow it to drain into the sub base or could i run a shortish section of 110mm under ground pipe perforated and wrapped in a geotextile under the drive with sub base compacted around/over it and then the sand and the blocks?
Thanks as always for any advice
ps you can see further extent of the so called "professionals" that laid my concrete base
ideally the acos should be attached to a soakaway but in reality as the slope is away your suggestion will probably act as a water bar,I have done similar on occasion,just as a belt and braces thing

As in a bar to stop water, a physical barrier rather than an active drain.
Dig a grip out(trench) and line it with some geotextile and then get some 100mm waving coil(perforated land drain pipe) should be able to get small lengths of it.
Connect that and fill with clean pipe bedding
Wrap up like a present and top off with your mot
