Thin concrete ground covering question
Hello all
I'm living overseas in Japan right now. I'm looking at an alternative to just using gravel to cover the ground, and a proper concrete slab is far too expensive. I outline the project here for making a very thin concrete ground covering just for light foot traffic and to stop weeds. If you could answer any of the questions it would be very helpful. Thank you

Dig out the area about 6" down.
Expensive way
Lay down geotextile, 1" of gravel, another layer of geotextile, another course of gravel.
Cheap way, same as above, but use tyvek
Really cheap, just lay down used carpet instead of geotextile.

My pistol firing range is carpeted. Nothing fancy. Just regular indoor carpeting laid directly on the ground. It's all synthetic so it holds up surprisingly well. Mine is mostly protected from the sun but still is doing the job after 5 years. If exposed to full sun it might only last a couple years.

Thanks guys. I was hoping for something harder. I've already poured a couple walkways and a small basketball court. They're holding up pretty good, although the court is already starting to crack, which I was expecting. Maybe this solution will be good enough if I could come up with ways to make the thin concrete more durable. Metal lathe, plasticizers, thicker aggregate then sand? Maybe pouring sand under the slabs and making them a bit smaller would help them shift around a bit and not crack?

If you're looking for thin concrete, then grit/screenings/stone dust from a local quarry
mixed with a little lime would likely work.
Grit is angular crushed rock about the size of popcorn kernels, screening are the stone
& dust that sieves through the finest quarry screens.
It packs down to a very hard surface, you need a shovel or pick to break it up,
so walking won't disturb it.

That's a great idea. I couldn't find any lime locally, except the stuff used for disinfecting ditches and what not. Portland is really cheap though, so I imagine I could just mix some of that in.
How would you apply the mix, wet or dry?
