Beveling weakens tile seams, creating high susceptibility to seam deflection.
To minimize fractures, some manufacturers cut the tile on a slight angle, or bevel. Bevels between adjacent tiles create voids, or air pockets. After installation, these air pockets become the weak link in the floor. Once the tiles are set in place, the air pockets cannot be filled. On the surface, the tiles butt against one another, rendering air pockets or voids inaccessible from above. Variations in the concrete substrate prevent installers from controlling the millage of the adhesive, so air pockets cannot be filled from below, either.
Point loads can crush any floor at its weakest point. Adhesive is far softer than solid vinyl. When heavy loads rest on seams that are filled in with adhesive, seam deflection can occur, crushing tiles or popping the seams. The only way to avoid this potential problem is by creating a perfect 90-degree angle on all four tile edges, through the entire thickness of the tile. Perfectly milled tile rests snugly against adjacent tile, eliminating any possibility of unsightly gaps, while providing extreme resistance against heavy loads.
