Tactile Tile Skid Resistance

By Aaron McConachie

Our research on the small diameter truncated domes, spaced farther apart, indicates that there would be a loss of tactile tile skid resistance, both wet and dry, as measured by industry standard test method, ASTM C1028-89. “Determining the Static Coefficient of Friction of Ceramic Tile and Other Like Surfaces by the Horizontal Dynamometer Pull- Meter Method”. In layman’s terms, this reduced tactile tile skid resistance is a result of the reduced surface area in contact with the sole of a shoe. For example, a man’s shoe (size 11) is approximately 4” wide, which if placed on the center of a dome, would not extend across to reach the adjacent domes on either side, leaving the sole of the shoe to rest on only one single row of two domes, which are, in total, less than one square inch. This problem could be further compounded with a smaller shoe, and in particular a woman in high heels whose sole might be expecting to gain a sure footing on the top of one single dome.

Armor-Tile’s truncated domes measure 0.9” base diameter, 0.45” top diameter, 0.2” height, spaced 1.67” center to center between adjacent domes, or 2.35” center to center measured diagonally.  This dome size and spacing provides the greatest underfoot detectability of any detectable warning surface on the market.
