Question for you on the subbase. I’m doing my own patio and am a little hyper focused on the slope. Does the dirt have to be a perfectly flat, sloped surface or if it has a little bit of variance can it be made up with the road mix? Trying to make sure I do it right and am new to this. Thanks!
Hi , complete novice here. Your drain pipe, how does the surface water get into it ? I see it is wrapped in black membrane/ material and then stone inside that over the drain pipe ?
The black material is a geotechnical/drainage cloth designed to let water pass rapidly through, while stopping fine silt particles. So the water flows across the surface of walkway, through the drainage cloth and drain rock, then collects (if there is enough water) in drain pipe and is taken away.
