were able to converse between the general contractor, architect, and the Noble Company technical sup- port team to fine tune the water- proofing details for this above- grade, raised-platform installation. Noble-Flex® drain flashings were an integral part of the sheet mem- brane transition-to-drain detail. The prefabricated drain flashings, inside, and outside corners ensured a smooth transition for these three details. Historically, Noble Company has had no issue working with a vari- ety of thinset and epoxy bonding agents for either bonding of the sheet to the substrate or bonding tile or stone to the polyester scrim. Over the last 30 years, Noble has worked with every major thinset/ bonding agent manufacturer and has no documented cases of bond- ing failure for products meeting ANSI A118.4 due to incompat- ibility of any company’s thinset and Noble’s sheet membranes. In this instance, Dal-Deck, a private- label version of Noble Deck sold through Daltile, was used. Working together, the project team and Noble Company were able to complete the project within five weeks, to the satisfaction of both MGM/Mirage Designs and visitors to the Bellagio property. Parting wisdom The biggest challenge and temp- tation for installers approaching exterior work is to carefully vet the quality of the work done by other trades, prior to the scope of work commencing, and resist the urge to second guess design and engineering already in place. Secondly, a survey of the indus- try will reveal there are very few Division 9 waterproofing and crack-isolation products rated as primary waterproofing over occu- pied space, so make sure the product can perform as per plan and specification. Projects in which tile and stone are installed in exterior settings, utilizing waterproofing and crack isolation will always be a part of the potential scope of work avail- able to an installer. Truly, the devil is in the details with these types of projects. Hopefully some of the informa- tion provided here can be of some assistance.

The finished work had to stand up to significant thermal expansion/con- traction, and provide a waterproof sur- face, which allowed rain water to funnel to drains and scuppers.
