Granite and Stone Fabrication Process

Once you choose your granite or stone from a myriad of possibilities, deliberated on custom edging, figured out cut-outs and other treatments, and carefully measured and/or created a template of you project, we are ready for the Fabrication process.

A slab of granite or other stone is moved from the supplier to the Fabrication Facility in Cumming, Ga where it is washed and measured. These slabs vary in size and weight but are generally upwards of 6′ by 10′ and weigh in the hundreds or thousands of pounds. Special equipment is used to position these slabs including suction cup like tools so as not to damage the piece.

Once the piece is positioned on a machine with a programmable diamond cutting blade on a table like surface, the skilled operator programs the cutting and sets up the piece to be cut based on the template and/or skillfully measures out the cuts needed. The diamond blade then slowly makes the cuts with a stream of water that both cleans away the debris and, most importantly, keeps the blade cool. Without the cooling water the blade would fail in minutes. Only very skilled and experienced craftsman can operate this cutting tool. Often many passes are needed to complete this part of the process. The piece is then checked for quality and precise specifications.

Depending on where the piece will be used, cut-outs are done using the same method as above but often with hand cutting tools. If the piece is a counter with an under-mount sink, a hole is cut for the exact dimensions needed for that particular sink. Again, a suction cup like tool is used to hold the part being cut out. If you have chosen a top-mount sink or cook top this process may be done at the project site. Again, the piece is checked for quality.

The pieces are then given edges, using methods similar to woodworking, but using diamond blade or diamond tipped tools cooled with water. This step in the process is where craftsmanship is paramount and this part of the process may involve multiple steps depending on the edge selected. Yet again the piece is checked for quality.

Polishing is the last major step in the process and may again be completed in multiple steps and combined with edge cutting depending on the edge treatment. Industrial diamond pads of various grits, similar to sand paper, are used on a polishing tool similar to a random orbital sander. Water is again used to cool the polishing pads and clean away the debris. At each step in the polishing process finer and finer pads are used to achieve that ultra smooth finish and beautiful look only natural stone or granite has. And, of course, quality checks are done.

This brief description is but a snapshot of all the detail that goes into a natural stone product. There are literally dozens of applications for natural stone products so other steps in the process may be needed depending on those applications.

The piece is then carefully checked and re-checked one last time before it is delivered to your project location.
