[Ferro List] FC Sphere leveling

[Janoahsh]

Thank you,
Mud Jacking does sound like a good solution.  Do you have any idea what size
pipe and how much pressure is involved?  I've only heard of it and thought
it would require greater pressure than PVC would handle.  PVC would
certainly conform to the shape more easily.
When you say just below half way to the bottom, do you mean just below the
1/4 sphere horizontal line?
Ditching above the structure helps a lot as well.

You would want to jack tangent to the sphere to change the level that way.

Mud jacking can be just mud or sand and mud. Not every body uses grout.

To mud jack a sphere the pump line goes just below 1/2 of the distance to 
the bottom. Just set some PVC pipe in place so you don't have to drill for
it.

Sheet piling uphill to 6 ft should stabilize the rotation of the sphere,
ground will 
still move but the top is not much faster than 6 foot down.

My choice - pipe for mud jacking and use sand with mud or the dirt that is
already there.
It will 'float' just like a drive slab or a boat.
