Pool Water Tightness Tests

What is the definition of a water tight swimming pool?

Believe it or not, there is not agreement on how a swimming pool should hold water.  The differences centers around being water tight before or after the final finish is applied to the pool shell.  An example would be should the pool be water tight before it is painted, plastered or tiled?  It is this writers opinion that the swimming pool owner is buying a water tight pool shell and a coat of paint or other cosmetic surface should not be considered the source of water tightness.  As a result, all pools should pass a water tightness test before the final finish is applied.

This conversation gets more interesting when the shell is placed using a cast in place method or a shotcrete method.  Some in the industry have taken the position that shotcrete is not waterproof, but water resistant.  It seems silly that someone in the swimming pool industry would make an argument that the pool shell should be water resistant.
