The process with Marble and Granite
Quarrying natural stone and installing it in someone’s home is an incredibly long and arduous process. Removing a 40,000-pound block of natural stone from the earth and turning it into a handcrafted countertop or gleaming marble floor is not easy. There are many steps and intricate details which cannot be overlooked in order for a piece of stone to find the perfect setting where it will look beautiful for years to come.
The first step to finding the perfect slab is finding an optimal deposit of material with desirable color, pattern, and composition. This requires geologists to look for stone outcrops which are more easily examined since the bedrock is exposed. Samples are then obtained by boring into the earth to take core samples with expensive diamond-tipped drill bits. These samples are then tested to determine if the stone is suitable for use as dimensional building stone. Later they are polished so that their color and pattern can be examined to determine marketability.
Once blocks of stone reach the processing facility, they are cut down into smaller more manageable pieces. For slab materials, this typically means a trip to the gang saw. A gang saw works just like a giant bread slicer, with many adjustable blades that allow for the thickness of the slabs to be adjusted. The gang saw can cut the entire block of stone into slabs at one time. More delicate materials may require the use of a diamond wire saw to gently cut one slab at a time with less trauma to the stone. The most recent technology involves multi-wire gang saws which have the potential speed production on exotic materials exponentially.
After slabs are cut on the gang saw, they are moved one at a time to the polishing line, where they are laid horizontally on a large conveyer type line called a polishing line. There, they pass under polishing heads which begin with very coarse diamond abrasives, and then move to finer and finer grit abrasives, just like sanding wood. Travertine slabs and some marbles, will receive a cementicous or epoxy compound to fill the natural voids of the stone. Part of the way through this line, slabs of granite, marble, and onyx will receive a coating of a resin treatment which will fill in any pits or micro fissures which are inherent to the stone in order to make the final surface easier to clean. Most of the excess resin is removed by further polishing, with only 1% remaining on the finished surface. For materials where the final surface is to be honed, the process will stop with a lower grit abrasive than materials with a polished surface.
At this point the materials are checked for quality and carefully packaged for their long journey. Slabs are bundled together and braced with a wooden framework, custom built to ensure the slabs stay upright during the shipping process. The journey begins when the container is loaded by massive cranes onto a large ocean vessel. After about four or five weeks at sea, they arrive at US ports. Here the containers are offloaded with cranes, passed through customs, and transferred to the Riostones stores.
Each type of natural stone used in the construction industry brings with it inherent strengths, making them suitable for different applications.
