ADA Truncated dome tiles - Detectable Warning Surface

ADA tiles—also known as truncated dome tiles or detectable warning surfaces—are specially designed tactile ground indicators that provide guidance and warning to individuals with visual impairments. Required by the Americans with Disabilities Act (ADA), these tiles are essential for creating accessible environments in both public and private spaces.

Types of ADA Tiles

There are two main installation types for ADA-compliant tiles:

• Surface Applied: Designed to be installed directly onto existing concrete surfaces, ideal for retrofitting or quick installations.

• Cast-in-Place (Wet Set): Embedded into fresh concrete during pours, offering a seamless, long-lasting finish—commonly used in new construction.

Materials Available

ADA tiles are manufactured from various durable materials such as polymer, fiberglass, and galvanized steel, each engineered to withstand different levels of pedestrian traffic and weather exposure.

California Compliance Note

In California, ADA detectable warning tiles must cover a minimum cross direction of 3 feet across pedestrian ramps to meet state code. The linear length along the curb or pathway varies based on the width of the ramp or crossing zone.

To meet these requirements, our products are available in the most commonly specified sizes:
3'x2', 3'x4', and 3'x5'—ideal for ensuring full ADA compliance
