The slipperiness of the surface is measured by a dimensionless ratio called the ‘coefficient of friction’ (COF). As an example, a clean broom finished dry concrete surface will have a COF of about 0.70-0.80. TekWay® High Performance ADA Domes test at a COF value of >0.85.
A lasting slip resistance is paramount when manufacturing detectable warning tiles for the safety and well-being of the visually impaired community and all other pedestrians.
