Durable Concrete Warning Systems for Sidewalk Ramps
AlertCast® PAVER is a glass-reinforced thermoset composite detectable warning panel, designed for superior impact, slip, and wear resistance with long-lasting durability. Featuring a top panel with slip-resistant truncated domes, molded to precise ADA regulations and ADAAG specifications, it includes raised truncated domes with a nominal diameter of 0.9”, height of 0.2”, and 2.4” center-to-center spacing.
Our installer-friendly design incorporates side-flange vents (4” wide by 1” deep) combined with structural ribs and pre-drilled holes to eliminate air pockets, ensuring a solid and secure installation. With its homogeneous color, durability, and easy installation, AlertCast® PAVER is built to endure the demands of high-traffic areas.
Proudly made in the USA, it carries a 5-year manufacturer’s warranty, meets ADA compliance standards, and is approved by DOTs, ADAAG, and Caltrans.
