Abstract
Detectable warning areas (DWAs) and methods of forming the same are provided. A mat template having one or more holes can be placed over a substrate, and a dome-forming material can be filled in the mat template by pouring the dome-forming material over the mat template and working the dome-forming material into the one or more holes of the mat template. The mat template can remain in place until the dome-forming material is completely cured, and then the mat template can be removed. DWAs formed according to this method display improved properties, including increased bond strength.
