Helps people who are blind or visually impaired to safely negotiate areas of traffic.




The Overall Best Surface-Applied Detectable Warning

TopMark alerts pedestrians with visual impairment to stop and proceed with caution. The truncated domes on the surface of TopMark® are easily detectable by cane or underfoot.

New and improved features of TopMark® include:

  • Same durable material but with improved application method
  • New 2' x 4' sheet size plus 1'x2', 1'x3' and 2'x3' sheets
  • Easy-to-use dispensing guns for sealer and bonder paste
  • Lighter-weight TopMark Roller
  • No need for Edge Roller

These features plus the fact TopMark® does not require electrical tools, fasteners or anchors; is easy to cut for radius curves; and can be applied on new and existing asphalt and concrete surfaces (including green concrete) translates into a much quicker and simpler mobilization and application time saving both time and money.

TopMark® can be applied on new and existing concrete and asphalt. TopMark® is supplied in a convenient kit that contains the preformed thermoplastic materials and sealer needed to complete four typical 4 ft. x 2 ft. ramps (or 32 square feet of total application area). Since it only takes 15 minutes or less to complete a 4 ft. x 2 ft. application on a curb ramp, a complete intersection can be installed in a single trip to the worksite.

The flexible construction of TopMark® allows it to conform to irregular surfaces for use on curb ramps, blended transitions, mass transit rail platforms, and public loading areas. In fact, TopMark® can easily be cut to fit special curves and angles. TopMark® is available in yellow, white, black, blue and brick red colors.

Once installed, TopMark® provides a long-lasting, easily detectable surface that is slip-resistant and wheelchair friendly. TopMark® is compliant with the current Public Rights-of-Way Accessibility Guidelines as published by the U.S. Access Board and the ADA/ABA-AG (formerly ADAAG).
