AlertCast® is reinforced thermoset plastic engineered for superior impact-resistance, slip-resistance,wear-resistance and long term durability. Our exclusive design incorporates a top panel of truncated domes molded to exact ADA specifications for detectable warnings and bottom docking anchors that are embedded into wet concrete. The special concrete anchors lock the part securely into the concrete without trapping air beneath the part’s surface. This system is very lightweight and the panels maintain flexibility so they are easy and fast to work with during installations.
AlertCast® Detectable Warning
- Reinforced thermoset plastic engineered for excellent wear and strength.
- Safety speckled surface for added slip resistance.
- Two-part mounting system for wet concrete. Base anchors permanently embedded in concrete. Top panel can be easily unscrewed and replaced for a fraction of the cost and tearing up concrete.
- Innovative safety spars reinforce panel strength and increase traction for pedestrians
- In-line domes spaced on exact 2.35″ centers (A.D.A. 4.29.2)
- Exact required detectable warning length.
- Exact required detectable warning width.

- What is ADA Compliant?
For more information on ADA Compliant click here.
- What Are Truncated Domes?
Truncated domes have a unique design that can be detected underfoot and with a cane, and other surfaces are not considered ADA equivalent and therefore do not comply with the ADA requirements.
- What Are Detectable Warnings?
Detectable warnings, a distinctive surface pattern of domes detectable by cane or underfoot, are used to alert people with vision impairments of their approach to streets and hazardous drop-offs. The ADA Accessibility Guidelines (ADAAG) require these warnings on the surface of curb ramps, which remove a tactile cue otherwise provided by curb faces, and at other areas where pedestrian ways blend with vehicular ways. They are also required along the edges of boarding platforms in transit facilities and the perimeter of reflecting pools.
