Cast-In-Place ADA Truncated Domes Tiles for Wet Concrete Installation
Replaceable Truncated Domes Tiles for Wet Concrete Installation
While the Americans With Disabilities Act was passed in 1992, the jury was out on requiring truncated domes. But after years of commissioned studies, the ADA finally determined that truncated domes would be required for many applications on both public and private property where changes in surface, such as curb cut outs, parking lot environments, wheelchair ramps, and more, required a tactile warning system for persons with low or no vision, and, these days, to alert those of us who are temporarily attention impaired. (Read: Texting while walking and any number of other modern impairments to attentive and alert mobility.)
Cast-in-place truncated domes are applied when fresh concrete is being poured, typically on new builds. This allows property owners and managers to install ADA required truncated dome pads and meet local ordinances during construction, which saves time and money. A key advantage to some of the cast-in-place domes we offer is that they are replaceable truncated dome pads. Given that requiring the installation of tactile warning systems is now a permanent part of ADA accessibility laws, business owners and property managers like knowing that many years from now, the truncated domes they initially installed can easily be replaced with new pads—without requiring any concrete demolition or pouring.
Because of their size, weight, and industrial adhesive/moisture sealants, Truncated Domes can only be shipped by Ground Transport to a Business Address. Expedited shipping is not available. Questions? Contact us
Our cast-in-place truncated domes come in a range of sizes and colors (to meet ADA contrast requirements for paving tiles and truncated domes). NOTE: California requires a minimum 3-foot depth for truncated domes. Select your sizes accordingly.

ADAAG Requirements for Detectable Warnings
(March 2003)Detectable warnings are walking surfaces that are primarily intended to provide a tactile cue to pedestrians who are visually impaired. They are installed at locations such as the edge of a train platform or at the transition between the sidewalk and the street to warn pedestrians of the potential hazard that lies ahead.
The tactile properties of detectable warnings result from a grid of small, truncated (flat-topped) domes across the warning surface. This pattern has been standardized by the U.S. Access Board and testing has shown that the pattern can be detected underfoot or by cane without causing a tripping hazard or obstructing wheelchairs.
Despite the proven tactile benefits of detectable warnings, little research has been conducted to evaluate the visual detectability of various detectable warning materials. Detectable warnings that provide salient visual cues in addition to tactile cues may help many pedestrians with visual impairments to locate hazards or curb ramps from a greater distance than is possible using the tactile cues alone. Some pedestrians may use them to orient themselves to a curb cut or ramp at the end of a crosswalk.
