I've been lurking for a few weeks - lots of helpful info so far! Just wanted to share pics of my progress so far. I plan on ordering a test kit and will update details and equipment specs soon. They started digging on Tuesday and finished today. It is a gunite 20X40 with a small tanning ledge and a lot of bench seating in the shallow end. The table will be a granite rectangle. Still haven't picked out any plaster, tile, or coping but I know we are going to do the PolishedScapes plaster in a lighter color. All of the stone used will be Austin White like the patio in the background. I really had no idea that our ground was solid caliche at less than 3 feet deep!
