The Process for Granite Countertops Fabrication: Tools, Installation, and more! 

Due to their durability, beauty, and unique characteristics, granite countertops have become an increasingly popular option for homeowners and designers alike. With its natural stone composition and variety of colors and patterns, it’s no wonder that granite is one of the best choices for kitchen and bathroom countertops.

But what are the tools used in manufacturing granite countertops? How is the fabrication process carried out? And how are granite countertops installed? In this article, we will explore the answers to these questions and provide a comprehensive understanding of the process for granite countertop fabrication.

Tools Used in Manufacturing Granite Countertops

The primary tools for manufacturing granite countertops include:

Stonecutting Saws – These saws are equipped with diamond blades and are used to cut large slabs of granite into smaller, more manageable pieces. They use a variety of saws, including angle grinders, miter saws, and circular saws, which are equipped with diamond saw blades for different types of cuts.

Transport Racks – Once the granite has been cut into manageable pieces, transport racks are used to move the slabs around the fabrication shop. These racks allow for safe and efficient movement of the heavy stone.
Edge Profiling Tools – These special tools, also called stone routers, help shape and polish the edges of the granite slab, giving it a finished look. They use different grit levels of diamond polishing pads to achieve varying degrees.
Polishing Pads –  These pads are used in combination with the edge profiling tools to polish the edges of the granite. They come in different grit levels, from coarse to fine, and each one helps achieve a smoother and shinier finish.

The Fabrication Process

Fabricating granite countertops typically starts with selecting the perfect slab from natural stones or engineered materials. Once chosen, the fabricator will take measurements at your home so they can begin designing your countertops.   The fabrication of countertops can take anywhere from a few days to a few weeks, depending on the type of stone selected and other specifications, such as edge treatments and cutouts for sinks and cooktops.


Your fabricator will then inspect the slab you’ve chosen, looking for any defect in the material. They will check to ensure there are no characteristics that could affect the installation or performance of your countertops. Once the template is designed, they will perform a final inspection to ensure the material meets quality standards.


If there are unwanted spots on the slab, they will be marked by the fabricator so they can be avoided during the templating process. After a thorough inspection is complete, the template will be placed over the slab. This template is used to ensure the best cut of the stone is achieved. They are also used to ensure the pattern flows across the slabs for a cohesive look. Whether you choose marble granite or quartz, a fabricator will use a template to ensure the cuts enhance the beauty of the material.


After templating and inspection, the granite can now be cut. For this process, the stone will be cut with a water jet or a bridge saw. The bridge saw is most commonly used, but a water jet is also popular in some applications. These specialized tools allow the craftsman to achieve a beautiful, high-quality appearance.

Bridge saws utilize diamond blades to cut through the stone in a wet environment and are used to cut straight lines. The water acts as a coolant, keeping the blade cool and extending its life. On the other hand, water jets use high-pressure streams of water with an abrasive substance such as garnet to cut through the stone. Oftentimes, a water jet is used to create intricate patterns or circles.


During this stage, the fabricator will cut out the holes for the faucet, sink, and cooktop as needed. CNC machines are used to cut the stone to a 1/16th of its final size. Once these initial cuts are complete, the CNC machine will create the edges.


After the CNC machine has completed its work, the fabricator will polish the edges of the stone to achieve a finished look. They will use different grit levels of polishing pads and grinders to create a smooth and shiny appearance.


After the polishing is complete, the countertops will be sealed to protect them from stains and scratches. The fabricator will use a penetrating sealer that will be absorbed into the stone, creating a barrier against potential damage.

Quality Assurance

Once the fabrication is complete, the granite countertops undergo a quality check to ensure they meet the desired specifications. They will check to ensure the edges are uniform, measurements are accurate, and check the color to ensure it matches other areas of the stone. Any necessary adjustments or touch-ups are made before the countertops are ready for installation.

Installation of Granite Countertops

The final step in the process is the installation of granite countertops. This involves carefully placing the fabricated slabs onto the designated area, securing them with adhesive and sealant, and ensuring they are level and secure.

Professionals use specialized tools such as suction cups and leveling devices to ensure a smooth and seamless installation.

In conclusion, fabricating granite countertops requires specialized tools, precision cutting and shaping, and a keen eye for detail. From selecting the perfect slab to installing the finished product, every step is crucial in creating high-quality granite countertops that will last for years.
