Abstract
Apparatus and processes that include a detectable warning tile having a top side with a plurality of protuberances forming a pattern or array and a second tile member disposed perpendicular to an edge of the detectable warning tile. The bottom side of both the detectable warning tile and the second tile member have at least one anchoring member embedded within a concavity in the bottom side, making the tile and tile member especially durable on platform edges.
