What did you use to waterproof the positive/negative side of a raised spa?

[MachuMatt]

I am trying to find the right product for waterproofing the positive and the negative side of a raised spa with a vanishing edge. The inside of the spa will be Tile and also have StoneScape mini pebble below the water line. The top of the spa will be Tile and the outside (negative edge down to the waterline will also be Tile. I would like to make sure that the shotcrete is waterproof before we tile and then install the StoneScape mini pebble. If anyone has any recommendations on what product they have used or recommend, I would appreciate it.

Here is what my spa looks like for reference:

I wish my pool builder had used this behind my retaining walls he put in for us. Efflorescence pokes out here and there and I suspect this product would have prevented it.

You might want to look at a product called Vapor Shield by Multicoat. We have started applying it to the shell first and then waterproofing. Have had nothing but positive results so far.
