Diagram of the CSA Standard for Tactile Walking Surface Indicators, indicating critical dimensions for sizing and spacing of tactile elements.

The figure shows both plan and cross sections of a CSA Standard Tactile Walking Surface Indicator and states:

  • Install tactile walking surface indicators in a manner that avoids interference from an irregular walking surface, and does not create a tripping hazard.
  • Base surface ideally level with adjacent surfaces but never more than 3 mm above or below adjacent surfaces.
  • Surface to be slip-resistant.
  • Tactile walking surface indicators to be colour contrasted with adjacent surfaces.
