Of the two PB's I have narrowed it down to, PB 1 uses 8" thickness as standard for IG gunite, and PB 2 uses 6".
PB 1 - the one who uses 8" - is much more expensive than PB 2.
I asked PB 2 if I can upgrade to 8" and if it is a good idea. He said that he could do it for $1,700, but that his company didn't usually do more than 6" for a pool of my depth (4' to 6') and that he felt the money could be better spent on decking or landscaping, and that 8" was "overkill."
Your thoughts? (We are in N.C.)
