Industry’s best replaceable cast-in-place detectable warning

Patented PENETRATOR™ anchor system!

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.

Replaceable, uses patented PENETRATOR™ anchoring system
Simple wet concrete installation with minimal aggregate displacement and maximum holding capabilities. Easy tile replacement should the need arise.

Premium UV Treatment
Ensures long term color retention

Superior strength and impact resistance
Reinforced to over 30,000 psi, yet lightweight
