Digging out rotten fence posts

Postby JackOfPaulTrades » Fri Mar 11, 2011 8:12 pm

My parents have a concrete patio and driveway which were separated by a wooden fence with a gate in it. The wooden gateposts were sunk into the concrete - evidently no measures were originally taken for drainage, as they have now rotted and broken just below ground level.

Does anyone have any tips on removing the section of post remaining in the holes? I'd like to replace the posts (either with concrete ones, or wooden ones with some sort of drainage precaution) but as the whole area is concrete, I don't really want to get into smashing any of it up to get the old wood out.

You will not get the stumps out of the concrete pockets, digging out the post and concrete is the only option.

i did once manage to remove a rotten stump from it's concrete home by using a very long and hefty 22mm auger to remove most of the material from the centre. i was then able to prise the rest inward away from the edges to the centre using a crowbar and lump hammer.

it was a real work-up though, i reckon it must've taken me about an hour per post and i had 6 to do. couldn't dig the concrete out as they were part of the footings for a brick wall that had the wooded posts interspaced.

by the time i'd done all that i came to realise that the original posts were an odd size - 3"x3" were too small to neatly slot into the hole and 4"x4" too big!
