apologies for the odd question, but here goes.

We wanted to replace an old fence at the back of the garden. I thought there was a flat piece of concrete, about 1m squared, which needed to be removed before we can sort the fence out.

I started digging to loosen the concrete, and continued digging and digging until I realised that this is actually an enormous piece of concrete.

Eventually I dug all around it and its about 1 metre cubed!!

It's a long way from anything structural and so I have no idea what purpose it served. More importantly it must weigh over 2 tons. We hired an excavator to knock down an old garage and level off another part of the garden, so we were able (just about!) to pull this concrete boulder out the ground.

The problem is how to dispose of it. It simply can't be lifted, so I guess I need to break it up - suggestions needed please!? :eek:
 
bury it, deep and dark where the light will never find it, under it place a box, and in the box place a ring. In several hundred years someone will find the ring and create an entire history surrounding it and why it was sealed under tons of concrete.

haha! I have wondered if there's anything in it... or anyone?!? :(
 
Pickaxe and some hard work or if its got a few cracks fill those with water tonight.
Or simply pop to your local tool hire place and pick up the biggest hammering tool you can hire.
 
Rats can chew through concrete, can't they? So I'd put a big lump of cheese in the middle, then seal the hole with more concrete.

I may not have thought this through completely.
 
Is it an ex-council/local authority house?

Mine was built by the Corporation of London when poured concrete and chain-link fencing were cheap as chips and the foundations for the fence at the bottom of my garden look like someone buried a 10 metre section of the Berlin Wall.

We had a washing line pillar halfway down the garden with a poured concrete foundation that was the size a van wheel. Had to dig it out and smash it up with a Kango hammer as my 14lb sledgehammer hardly marked it.

Took 3 trips to the hardcore skip at my local recycling centre to get rid of it.
 
Chip away at it from all sides with a Kango "jack hammer, I doubt there will be reinforced with steel,should take to long,could have been from some left over concrete from the footings or something and just wanting to get shut before it goes off.
 
Fluoroantimonic acid I believe the only thing that can contain it is teflon everything else gets stripped off it's electrons

There was a news story a few years ago about a chap finding a smaller cube of cement in a garage he acquired. Upon breaking it up he found a baby's remains inside.

So, you know, be prepared for anything.
