Thank you guys for the advice. More info: It is a crude oil tank with a diameter of 70m. It passed the 'fat guys test'. The bottom plate was punctured due to MIC attack. Through the 10mm dia hole, we can see a void approx 40mm (measured gap distance from underside of bottom to the soil). So far...
How do you address voids underneath the bottom plate. Should we cut the plate and refill the void with compacted soil? Is there an acceptance or rejection limit for voids beneath tank floors? Your experience and expert advice is greatly appreciated.
