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 ?

The way the foundations are constructed should either have been passed in by
Building Regulations, or you should be having this discussion with a BCO who
I doubt will be very happy with this idea.
