Anyone know of a method of digging deep foundations easier than mini-digger in a limited space ? For example, I need some 2m foundations which is quite deep, liable to trench collapse, and is near a deep sewer, may need shuttering etc. I can imagine digging say the bottom metre using some sort of hole-digging device / big corkscrew or whatever, producing what you could call mini-piles. Pour each hole individually, allow to set, dig next one etc. I would just need a suitable device. I'm sure I've seen such a thing on the back of a tractor. A 2m trench seems deep, but a 2 meter "hole" does not, particularly. Any thoughts ? Simon.
