The employee services building was designed right into the side of the mountain next to the Westin Hotel, which also utilized Krystol Internal Membrane (KIM). Substantial mountain run-off was expected to be a problem.
In the summer of 1998, in very hot 33°C (92°F) temperatures, the foundation walls were poured over 3 meters (almost 10 feet) in height. Both the KIM admixture and the Krystol Waterstop System were installed in the walls and the suspended slab as the sole waterproofing system replacing membrane requirements. To date the system is performing as specified.
