We have come across a crew that we would like to use for our pool remodel. They do work for a few of the big pool remodeling companies around town. This crew uses hand mixed concrete to create their pool shelves. They use rebar and finish as expected. I have seen multiple examples of their work, and there do not appear to be any issues with this method.

Is there a negative of hand mixed concrete vs shot in gunite? Are psi that important?
