Why do sidewalks have raised, colorful domes on sidewalk ramps? Why do airports have raised strips on walkways? Most people move throughout public spaces without understanding the purpose of these tactile surfaces underneath their feet. Yet, for specific people in our society, these tactile surfaces are the difference between independence and dependence.

First and foremost, detectable warning tiles and surfaces were designed to assist individuals with disabilities to safely navigate public spaces, and then, in 1991, the Americans with Disabilities Act (ADA) mandated the use of detectable warning tiles in public areas throughout the United States.

Choosing detectable dome tiles comes down to seven key considerations starting with ADA compliance. Detectable dome tiles require a high level of durability to withstand constant pedestrian traffic and heavy motor vehicles. Beyond the general traffic, detectable warning dome tiles also deal with extreme temperatures and weather patterns.

When choosing detectable dome tiles, consider these important factors for choosing a dome tile that meets ADA compliance standards from color to durability.
