Alertcast Detectable Warning
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.
