Hey all - I've started my new project this weekend, which is going to be essentially a 30sq meter patio. One key thing, while not a driveway I do want to be able to bring a car or motorbike onto this.
I've dug out enough for a good solid 150mm (lower in places cos I'm no digger operator!) Type 1 MOT subbase and I'm still at what I would basically consider top soil. More worryingly, in places I'm still pulling out literal rubbish - bricks, broken glass etc so it's almost definitely been "made up" at some point.
In other projects I've been in a position that I can go down to the sand layer, but the sand is much lower here. I think it's another 300mm down, at least - possibly further towards the back.
Basically - what to do? I'm happy to dig it out - that bit is easy (ish), but I'm already looking at 9 ton of Type 1 which isn't gonna be a laugh. Will a geo-textile and 150mm of Type 1 be good enough do you think?
