Features of a Good Quality Detectable Warning Surface

Detectable warning surfaces are something that all of us notice on roads and walking paths. These surfaces provide a valuable protection for individuals with visual impairments. They essentially serve as a warning that requires their attention ahead while entering a busy intersection, a rail platform drop off, and so on. In addition, these warning surfaces also alert non-visually impaired individuals who might get distracted on such places for a couple of reasons to stay safe and careful. According to the Americans with Disabilities Act (ADA), detectable warning surfaces are defined as a distinct surface with a pattern of raised domes that can easily be detected by the use of a cane or feet and serve to alert people of their approach to hazardous locations.

Features that makes them desirable
There are many parameter a detectable warnings surfaces should qualify, in order to become a preferable choice. The manufacturers are experimenting day and night to produce a kind of concrete detectable warnings surfaces that has increased functionality. Among various other variants concrete detectable warnings surfaces have proven best performance. The following are some of the key features that has led to a better performance.

1. Durability
A detectable surface is exposed to a lot of rough situations. It is not just felt by human feet by other vehicles like trucks, cars are also moving over them. With such heavy loads, a good detectable surface will be the one who can withstand these activities and last longer. Concrete detectable surfaces are considered most durability because of its ability to stand in place for a considerable amount of time despite of all the heavy activities going over it.

2. Weather resistant
Weather is something no one can control. Extreme weather conditions like storm and cyclones can completely destroy any well established thing. A superior quality detectable surface is the one that does not get affected by sudden and frequent weather fluctuations.

3. Replacement
The ease to replace a out of function surface is always an added plus point. Broken or flat detectable can give rise to many unwanted accidents. To avoid that they are to be replaced as soon as possible. With easy to replace trait, the road or the place where replacement is to done is back on track without any long delays.

4. Size
The warning surfaces must have a series of tactile domes over a radial, square, or rectangular grid that meets with the ADA requirements. The warning surface should measure minimum of 24 inches long in the direction of travel and extend the entire width on the surface where they are being installed.

The above checklist should always be followed, whenever you are heading to purchase concrete detectable warnings surface for your building.
