Hello yet again. sorry to post so much, I’m WFH full time due to illness and I keep spying more jobs and thinking of more questions.
I intend to lay two 3x3 approx patios either side of an extension. this extension’s footings are very shallow - presumably raft foundation. Ahead of the patio is a inch step (wooden sleepers) servicing as a retaining wall for grass.
My question is, what would your approach to water runoff from the patios be? I’ve had quotes for this work and everyone has a different option, from aco drains, to soak ways, to French drains, to leaving it. One suggestion was French drain, pipe underground to 5m away from house into the earth in the far corner. Another wanted to aco all around the edges to plumb into existing drain gulley.
I think I’ll do this myself now and my instinct is to simply angle the patio away from house so water runs into a little trench with pebbles and gravel to drain away. There is patio there right now with no drainage consideration at all - aside from gravel around it - and we’ve never had flooding or pooling. It is unsealed Indian sandstone with poor sub base so I wonder if its draining through the gaps there, which won’t be present if redone solid and proper.
What approach would people here take?
I intend to do this later in the year but other aspects of the garden are being done first so I need to plan ahead.
