Do granite countertops have seams?
Granite slabs are limited in size by practicality. Quarrying, shipping, and handling issues place finite limits on the workable size of a slab. Often the raw slabs may not be large enough for the entire run of the countertop. Additionally, transportation and installation issues at the jobsite may limit finished piece size. As a result seams in the material are necessary. However, seams are very tight and filled with a clear or colored epoxy and are designed in a manner that minimizes (but may not eliminate) their visibility.
