I'm a little concerned about what I saw my PB doing to the gunite shell, could anyone comment on whether this is normal building practice?
The design had a short, straight vertical wall above grade, like you would have around a conventional gunite above-grade spa, only straight.
I expected the crew to form with plywood, but instead they used 1/8" pegboard supported by 1x4, 4' o.c. I had my doubts, but they claimed they knew what they were doing.
Well, as I expected, the sides came out wavy, and out of plumb by up to 3" horizontal in 12" vertical. To straighten this out, they came back 3 weeks later with a circular saw and power chisel, and spent a day and a half systematically chiseling away chunks of gunite until the walls were at least straight (they couldn't get them vertical since they were already exposing the rebar in places, but now it is only about 1" over 12" out of plumb) and then added a finish layer of concrete over that.
So my questions:
Is this the standard way to finish the form-side of an above-grade wall? Is there any risk that the structural integrity has been compromised by all the chiseling? If so, what should I do?
Is there any way at this point to get the wall vertical?
If this was not the correct way to tackle the job, how should it have been done?
