Non-replaceable engineered for ease of installation and minimal air entrapment

AlertCast® PAVER is a glass reinforced thermoset composite detectable warning panel engineered for superior impact resistance, slip resistance, wear resistance and long-term durability. AlertCast® PAVER features a top panel of superior slip-resistant truncated domes molded in accordance with ADA regulations and ADAAG specifications — raised truncated domes with a diameter of nominal 0.9”, height of nominal 0.2” and center-to-center spacing of 2.4”.

Our exclusive installer-friendly design incorporates four side-flange vents measuring 4” wide by 1” in depth combined with structural ribs on the paver’s underside and pre-drilled holes, all specifically designed to eliminate air pockets underneath the panel, ensuring an exceptional and solid installation. Boasting homogeneous color throughout, durability and ease-of-installation, the AlertCast® PAVER can withstand the rigors of demanding applications.

AlertCast® PAVER is proudly made in the USA, carries a 5-year manufacturer’s warranty, is ADA compliant, approved by DOTs and also compliant with ADAAG and Caltrans.
