Granite countertops are primarily held in place through proper fitting, precise leveling, and often secured using methods appropriate for the underlying cabinet structure.
Securing the Countertop
According to the reference provided, one key method for securing granite countertops involves the use of wood shims. This technique is particularly important in installations where the existing cabinets or the floor are not perfectly level or plumb, such as in older homes.
- Wood Shims: Contractors use wood shims to create a level surface on top of the cabinets before placing the granite. These shims fill any gaps between the cabinet tops and the granite underside, ensuring uniform support and preventing the granite from rocking or cracking due to uneven pressure points. By shimming, the countertop is effectively secured and leveled on the cabinet base.
Joining Granite Pieces at Seams
When granite countertops are made of multiple pieces, the seams where these pieces meet are crucial for stability and appearance.
- Epoxy: For the seams, contractors use epoxy to cement the granite pieces together. This creates a strong bond that holds the individual granite slabs in place relative to each other.
- Blending and Coloring: To make the seams as inconspicuous as possible, technicians blend and color the epoxy on-site to match the specific granite pattern and color before applying it. This skilled step helps the seam blend visually with the surrounding stone.
In summary, while professional installation involves precise cutting and leveling for a stable fit, wood shims are used to secure the countertop, especially on uneven surfaces, and epoxy is used to join multiple pieces together at the seams, contributing to the overall stability and integrity of the granite countertop installation.
