Granite and other natural stones are comprised of a variety of different mineral deposits, which are formed deep in the earth’s crust. It is the different mineral make up of the stones that create each stone’s unique look and color. While the mineral composition makes each color stand out, it also determines the stone structure. Most granites are very hard and durable, but there are some that are considered more fragile. When a fragile stone is selected, care must be taken during the fabrication process to prevent breakage. Most reputable fabricators use a technique referred to as “rodding” to provide extra countertop reinforcement in more fragile areas, such as those in front of, or behind a sink, or a cooktop cutout. Rodding involves creating a groove in the bottom of the stone and inserting a metal rod and then filling it with resin.
The rod offers additional support and provides more resistance to bending to the countertop.
Following are a few pictures of stone that has been rodded:
