Alert Cast

Industry’s best replaceable cast-in-place detectable warning
AlertCast is a glass reinforced thermoset composite 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. While incredibly strong, this system is actually very lightweight and easy to work with during installation.

Patented PENETRATOR™ anchor system!

  • Set in wet concrete, UV treated reinforced thermoset composite, replaceable.
  • Patented PENETRATOR™ anchor system, faster installations with less aggregate displacement and better hold.
  • Shipped ready to install – anchors in place, protective sheeting with bi-lingual instructions on each panel.
