Proper Detectable Warning System Installation

Detectable warning installation is a deceptively simple process, developed over a period of ten years, through extensive research and development.

The best approach to detectable warning installation varies from supplier to supplier, though certain aspects pertaining to the product are consistent. According to the Americans with Disabilities Act (ADA), all detectable warning installations must consist of a series of truncated domes measuring 0.9 inches in diameter, 0.2 inches in height, and spaced 2.35 inches, centre-to-centre.

Whether it’s 3 or 5-step process, the basic instructions involved with detectable warning installation are positioning, embedding, and edging around the panel. The panel must be set in place on a flat surface that is dry and sound. Some companies suggest sinking it into concrete for maximum integrity. Following the installation instructions to the utmost detail will keep residents safe from harm once the detectable warning installation is complete.

The day before the installation is to take place, it is a good idea to perform any additional maintenance to the installation location. This may include such retrofitting as sand blasting, pressure washing and/or vacuuming. Such measures will ensure the location is dry and ready for installation.

The locations in which detectable warning installations are commonly found are curb ramps, transit stations, pedestrian crosswalks, high traffic areas, reflecting pools, and any other pedestrian areas where a blind or visually impaired person may require assistance.
