Correct Base for Stepping Stones

I am planning to put stepping stones in my front garden and curious what people here recommend for the base.

Most of my research indicates a lot of people just put them on dirt. I have seen others who use a layer of concrete on top of the dirt, and finally a few use an actual crushed stone base with a 1" sand base.

Any recommendations? The stepping stones are concrete pavers from Lowes and will be arranged as below - level with the ground with river rocks around them.

They will not get a ton of traffic but want them to stay put.

There is no support or drainage requirements they are simply sitting there, nothing needed!

I wouldn't really call those "stepping stones" since they really won't be used for walking. I would just set them on the ground and landscape around them.

The front ones are likely more decorative. The ones in the back on the left side of the pic will be used.

That said, they will get some foot traffic. Still no base needed?

You can excavate underneath where the stones will go. Backfill the holes with compacted, clean, crushed stone. Then set you step stones in a bed of sand or stone dust.

Thanks - that's what I'm thinking is the right thing to do.

How deep? I was thinking 7" - 8" of fill including sand?

Yes, 7-8" of base (with sand) is a good amount. Do not skimp on the compaction when you put stone into the hole. This is the foundation for the stepping stone.

One thing the base of clean crushed stone does is to allow water to drain away. Without water in the soil underneath it can't freeze and heave in winter. Ideally your crushed stone would go all the way down below the frost line but with a stepping stone I don't think you get much benefit going more than a foot deep if just doing the area underneath the stepping stone.

OMG, and to think I have many of these sitting in beds on top of the wood chips. A wall yes, a simple stepping stone, well noting wrong but WAY WAY over kill!

Heck if your going that route, how about some drainage tiles!

Thanks. My frost line is 32" - 48" so I can promise I won't be going down that far for a stepping stone .

Worst case it will heave/move but nothing will be falling down as a result.
