Has anyone built a low (18" - 24") retaining wall using paving slabs,

I'm wondering how much concrete 'foundation' to use.

But you might try using none. My father used paving slabs as a retaining
wall with no foundation - the trick is to lean them back slightly, and the
maximum inclination will be defined by the stability of the soil. Clay is
best, since you can put the slabs in at about 80 degrees. Obviously soil
type is major factor, and it will be very tricky to do if you want any sort
of curve.

There is IIRC something on Cormaic's site on this:

My Father built a retaining wall all around his garden using broken
paving slabs - free of charge form local council. Height was about 18"
No foundations used - just trench dug to get down to clay ... and
courses laid off that.
He (or more to point we) split them into pieces around 8-10" deep,
random length and lay them like drywall stone with exposed aggregate
side facing out ... worked well and free.

Do you mean a 'flag on edge' retainer, where a single
flagstone is set near vertically into the ground and then haunched
with concrete, or do you mean where broken flags are stacked on in
courses to create a wall?
Both techniques are illustrated on my site. Whether you need a
foundation depends on the ground conditions and the use to which you
are putting the retainer. Generally speaking, a foundation should be
100-150mm thick and at least 300mm wide.

Thanks, I meant

I was thinking of using 900x600x50 flags with gaps for fence posts at
intervals for which I would be setting metal spikes in the 'foundation'.
