sub foundation washout
sub foundation washout
(OP)
We have an old building at the mill and one u-drain had a hole and washed a lot of soil under the slab and also under the footing of few collumns. so we have a huge cavern and the access to bring material is difficult as it is at the center of the building.
the plan is to resolve the sewer issue and then replace the sub foundation under the footing...
the difficulty is the access to the location so some people suggested to pump lean concrete into the hole.
I was wondering if someone have suggestions on this or on a other approach
the hole is about 20x20x40 ft3, some footing are floating in the air some are partially supported...

Make sure you can define the full extent of the problem, or your solution may be inadequate, and you may be on the hook for future problems.
You might need a 2-step solution. Fill immediately (for safety), then GPR or some other non-destructive testing to check for subsurface voids.
