Cities and businesses are scrutinizing pedestrian walkways to determine how to best increase the ADA compliance of public spaces. ADA compliant sidewalks make businesses and public areas more accessible to individuals with disabilities. A key component of an ADA compliant sidewalk is the truncated dome tiles that warn pedestrians of a change in the sidewalk, whether an intersection or a ramp.

These truncated dome tiles have two common ways of being installed: cast-in-place or surface-applied.

The Americans with Disabilities Act (ADA) sets a number of standards to govern curb ramps and to determine wheelchair accessibility. Curbs create an increased likelihood of injury or accidents for people who use a wheelchair or walker. For a person with a disability, curbs without a ramp could become unusable and be considered discriminatory.
