"I had a client that insisted on having a 20”+ unsupported overhang on her island. I tried explaining the physics to convince her that it was a bad idea. When I was able to pull out the Dimension Stone Design Manual to prove that it should not be done and we would not warranty it, we were able to work to a better long term solution to meet the client desires and stay within guidelines of the Manual to ensure successful project."
