Stone install specs

Hello. I am looking for official documentation reguarding deflection (ie: Tca or ansi) I am doing a stone floor installation in a residential kitchen for a builder. I mentioned to hime about the defletion needed to go beyond the L360. I told him it needed to be L720. But I cannot find this written anywhere in my TCA book or ANSI guides. I wanted to fax them this info. Could someone point me in the right direction?

Thanks, Steve

Someone will be along here with a link or you can click on the tile school link on the right hand side of the page here and send them an email and ask. They might have an answer for you.
Good Luck

Steve,
this is from ANSI A108:
A108.01 General Requirements: Subsurfaces and
Preparations by Other Trades — 2005 [New]
A108.01.2.3 Deflection
Floor systems, including the framing system and subfloor panels, over which tile will be installed
shall be in conformance with the IRC for residential applications, the IBC for commercial
applications, or applicable building codes.
NOTE - The owner should communicate in writing to the project design professional and general
contractor the intended use of the tile installation, in order to enable the project design
professional and general contractor to make necessary allowances for the expected live load,
concentrated loads, impact loads, and dead loads including weight of the tile and setting bed. The
tile installer shall not be responsible for any floor framing or subfloor installation not compliant with
applicable building codes, unless the tile installer or tile contractor designs and installs the floor
framing or subfloor.

Interior Installation of Cementitious Backer Units ANSI A108.11
— 1999 [Reaffirmed 2005]
A108.11.4.0.3 Support framing shall be designed for a maximum allowable assembly deflection of L/360
under all intended live loads.
I couldn't find anything in ANSI about the L720 deflection requirement. The Marble Institute of America identifies L720 deflection for stone surfaces in their Stone Design Manual. I don't have a copy on hand to quote you chapter and verse.

Hope this helps.
