New driveway and parking area to the front of my house, about 130 sq metres worth. Sandy soil, v. good draining therefore want driveway to be permeable. It's wholly a private driveway, so only light use, maybe the occasional delivery van. We have a digger and dumper hired next week for the operation.
Just want to check I'm roughly in the right area with this method:
Dig off 150mm
Put in timber stakes / gravel boards to mark actual edge of drive
Douse with copious amounts of weedkiller.
Line with geotextile membrane
MOT type 3 subbase, 115mm ish, compacted but not smashed to pieces.
20mm traditional Cotswold gravel 35mm, again compacted a bit.
I was thinking of just using my car to compact the subbase, rather than a vibrating wacker? Dont want to smash the stuff up to dust and make it into a type 1 material which wont be permeable.
Am I in the right ballpark?
