How does the jigsaw interlock between rubber tiles work?

The jigsaw interlock between rubber tiles is formed by alternating projections and matching recesses along each tile edge: the projections on one tile engage with the recesses in the adjoining tile, creating an edge profile similar to a jigsaw. Depending on the range, the projections are dovetail-shaped or rounded. In both cases, the head is wider than the neck, and the profile extends through the full tile thickness.

To lay the tiles, each tile is pressed down from above into the jigsaw interlock of the adjoining tiles already in place. The wider head prevents the tiles from being pulled apart across the surface; the interlock can be released only by lifting a tile vertically and holds the laid tiles together through their full thickness.

Where all four tile edges carry the same profile, the rubber tiles can be placed together from any side. Otherwise, the laying direction is specified by the profile. Bonding and perimeter edging are generally not required.
