Update on build. Next step: Waterproofing. I did a lot of research and got a bag of Masterseal 581 (Thoroseal) and a gallon of MasterEmaco 660 (acrylic fortifier) from Borders. These products are pricey! I used a mortar sanding block first to smooth the shotcrete, brushed the surfaces and applied the Masterseal 581 as directed. You put 1/3 Emaco with the water and mix to a pancake batter consistency. Then brush on with a roofing or wallpaper brush. Not too hard. This is what I did on the inside of pool and basin. I put 2 coats on the spillover wall. For the outside wall, which is raised and some will be exposed, I bought a few bags of quikwall from HD. I like this stuff. I added some Emaco for maximum water resistance. I may put some rock or something else on the wall later but I have to watch the bottom line for now. If I can get the walls smooth enough I will paint the quikwall.
I also have begun waterplug patching around the pipes. I bought two products, Masterseal 590 and Quickcrete Waterstop Cement. These products set FAST. I only hand mix about 16 oz at a time. The Quickcrete sets faster, but seems to be harder in the end and is cheaper than the Masterseal. I was freaking out about horror stories of it setting in the container and at first mixed too thin. This is a mistake, because you can't work with it too thin and it sets at about the same speed. It stays runny until the cure time and then all of the sudden, Pow! hard. I now mix to the proper consistency, wet the areas before I mix and work efficiently with a small spackle spatula.
