Hi waiting to hear back from the PB. We've had heavy rain for 10 days after the hole was dug and part of the dirt wall collapsed and the framing had to be repaired. Now that the gunite has been poured, there is a thin section in the problem area. goes from 11" to about 7" on top, and looks to be even thinner under the beam in some areas shown in the second picture, is this going to be a problem? if so is it repairable?
