Default Coarse gravel driveway

Pity. Did they lay the rubble just before you bought the property? If
so, they probably didn't bother with compacting it (typical), which you
should try as a remedy. You'll need to make 3-4 passes with the WACKER.
Wet it down beforehand (like, REALLY wet it down).

Problem is you don't know what's UNDER that rubble, and the ground may
be variable.

No worries, you'' get there, although the 2" stones seem large, and may
be difficult to compact without an aggregate - you really need something
to consolidate and form that aggregate. You could try a fine(r) grade of
dolimite sand on top, then compact, water, and compact again. This
should set very hard.

Put your drainage in first, naturally! Might like to use buried PVC
seepage pipes into stormwater or a sump. If Drainage is not good enough
you will get subsidence and 'ruts' with the winter rains - no doubt.

Like most things, if you do it right once you should have a good result
for years, then you can top up the rubble occasionally and compact again.

Good luck. Please post the results, whatever remedy you try, as I'd be
interested to know.

The front driveway of the house we bought has been made with coarse
granite-type grey gravel of 1"-2" pieces. It is not stable and will
rut when - say even a garbage bin is wheeled over it. Perhaps the
previous owners never finished the project...

Can anyone suggest what can be added as a layer over it which will
bind it and make it solid, stable and less painful to walk on in bare
feet! :-) Crusher-dust was one suggestion, should it be watered in to
fill the gaps around the stones or what?
