The fabrication of a waterfall edge is a complex process requiring advanced machinery. The fabricator cuts the countertop edge at a 45-degree angle, matching it precisely with a vertical side panel. For the most premium results, the fabricator uses 'book-matching' or 'grain-matching' to ensure the mineral patterns or veins appear to flow continuously across the corner. This requires high-precision cutting, strong structural mitering, and careful support at the base to ensure the edge remains stable and free from chipping over time.
