QUESTION

What is the thickness tolerance for Engineered marble & quartz?

ANSWER

ANSWER - The standards for Quartz Stone or Engineered Stone, which is a man-made product that generally is made up of about 90% quartz with resin, are currently the same standards as for natural stone.

The MIA Dimension Stone Manual version 8 shows in their tolerance chart for fabricated stone that a stone with a thickness ranging from >5/8" to 1.25" (>15 to 30 mm) with a smooth finish, the allowable tolerance is +/- 1/8" (+/- 3 mm).
