Some stones are moisture-sensitive and can result in curling or doming when adhered, so there is a test (i.e. European Committee for Standardization [EN] 14617-12, Agglomerated Stone–Test Methods Part 12: Determination of Dimensional Stability) that can be performed to determine whether the stone is excessively moisture-sensitive.
