A contractor called the other day requesting "those handicap dots". He meant Detectable Warnings or as engineers and architects know them Truncated Domes. It occurred to me that, while we may see these yellow domed mats everywhere, so few actually know what they are, what their designed for, and even further some don't even know that they are mandated by the ADAAG section 4.29.

TILCO Vanguard is an Approved Installer of Vanguard ADA Systems liquid surface applied detectable warnings. Vanguards product can follow every contour and nuance of the surface in every and any installation.
