Truncated Dome Pads, Tactile Paving, Detectable Warning Surfaces
What is the Purpose of Tactile Warning Pads?
Tactile warnings provide a distinctive surface pattern of “truncated domes” or cones (which are small domes or cones that have had their tops cut off, or truncated) or “truncated bars” detectable by long cane or underfoot which are used to alert people with visual impairments of their approach to streets and hazardous drop-offs. People who are blind or visually impaired are alerted of impending danger from vehicle impact or a grade change.

Why Do I Need to Install Truncated Domes?

Division of State Architect (DSA) ─ 2011 California Access Compliance Manual: Detectable warnings. Curb ramps shall have a detectable warning that extends the full width and depth of the curb ramp, excluding the flared sides, inside the grooved border. Detectable warnings shall be slip-resistant and consist of raised truncated domes. The detectable warning shall contrast visually with adjoining surfaces, either light-on-dark or dark-on-light. The material used to provide contrast shall be an integral part of the walking surface. The domes may be constructed in a variety of methods, including cast in place or stamped, or may be part of a prefabricated surface treatment.

6 Questions to Answer Before You Buy Truncated Domes

  1. Do you want surface applied dome pads for dry concrete, or cast-in-place pads to install when pouring wet concrete?
  2. Are you in a city or state that has unique requirement, such as a minimum dimension requirement? For example, California requires truncated dome pads have a 3-foot minimum dimension in the direction of travel.
  3. What color pads will work for your project? California requires pads be yellow, but the ADA requirement for visual contrast can trump this requirement. If you needed to install tactile paving pads on a yellow surface, installing yellow truncated dome pads would offer virtually no contrast with the surrounding surface. As always, consult with your building code or access inspector for any non-standard or localized requirements, such as for dimensions or color of truncated domes, before making your purchase.
  4. Does the size of the domes and their spacing meet ADA requirements?Dome size: , 0.9″ base and 0.45″ top diameter. Spacing: 2.35″ center-to-center, in-line dome spacing meets ADA Federal and individual State requirements, including California.
  5. Does the edge of the pad meet the non-trip hazard ADA rule?Perimeter of tile must be designed to meet ADA requirements for surface height transition, often meaning a beveled edge. Keep in mind that pads when placed end to end must maintain the dome pattern and alignment. Truncated dome pads sold on ADA Sign Depot meet these requirements.
  6. Are the manufacturer and the reseller reputable? For example, do they provide easy to download product specifications and installation instructions? Do they include with your purchase all required hardware, adhesive and instructions for installing the pads? Surface applied dome tiles should come with tamper resistant anchoring hardware as well as industrial strength adhesive designed to work with the manufacturer’s product.
    Wet cement applied pads should come with vandal resistant bolts (Is it a replaceable pad? Then you will want the correct hardware so that years from now you can easily remove and replace any worn or damaged tiles.) The ADA requires that manufacturers confirm their truncated dome pads will last at least 5 years.
