Shotcrete being sprayed in the corner.
You can see the tube (bottom center) the shotcrete flows through to the pressurized canon.
Outside the mixer truck delivers the 'goods.' Timing is of the essence as multiple trucks come, but only after the one before is finished. Shotcrete must be spread quickly before it begins drying.
A good look at the spa one the shoot is complete.
Steps were done after the initial shoot. This pic gives you a glimpse of the tile work, too.
