Having nearly finished replacing the fence I have a large stock of

The local tip is very picky about throwing stuff like this away - two
small bags of hardcore per day, or it is 'commercial waste' and you
have to pay.
Now we are about to build a big shed with a concrete base.
It occured to me that we could save all sorts of aggravation if we
buried the old fence posts in the concrete base.
I would wash them first (power washer) to remove all the dirt and
detritus. This would presumably not be as strong as a brand new
concrete base, but then again this isn't going to do a massive amount
apart from being the floor to the shed.
As long as they were an inch below the surface then the surface
should be fine.

Any good reasons not to do this?
The saving on the bulk of the concrete required for the floor, plus
the saving from landfill and repeat trips to the tip all sound good.


Seems fine to me, though I would use a sledge hammer to "crack" them and not
lay them as a tin of sardines which could weaken the stability of the base,
(I think). Leave some space between them.

Once upon a time, when Noggin nogged in the Bad Lands, at a time of Biblical
Drought in England's Green and Pleasant Land as Dennis Howell became
Minister of Rain, not far from his constituency, I needed rubble to create
the base for a kitchen extension to our first house.

I raided the byways for stones and concrete that the less considerate had
disposed of.

As I lifted the tailgate of the Maxi, I wondered whether passers-by realised
what I was doing or thought I was indulging in inconsiderate tipping!

Fortunately George Dixon didn't pass by.
