Whether you have a retrofitting project or a new construction, selecting the right concrete detectable warnings is crucial. You need to make sure that it is up to date with the current ADA (Americans with Disabilities Act.) There have been many changes since the ADA first went into effect in 1991. If you are in charge then it comes down to you to check the acts and be up to date.
Location Requirements
You need to know what the location requirements are. For example, the ADA requires that the tactile warning surfaces are installed on rail and transit platform edges, reflecting pools, curb ramps, vehicle ways, and on hazardous crosswalks.
Spacing requirements
There is a measurement for the tile bumps that you have to keep in mind. The raised domes need to be of minimum 1.6 inches to a maximum of 2.4 inches. The spacing in between each adjacent dome must be a minimum of 0.65 inches.
Size requirements
The concrete detectable warning surface needs to consist of a series of tactile domes that is spread evenly over a square, rectangle, or a square grid. It just has to comply with the ADA rules. The warning surface has to be of minimum 24 inches long in the direction of travel and also extend the entire width on the surface that they are being installed.
Types of concrete detectable warning products
Apart from the ADA regulation, you also need to consider the different types that you could use on the particular project. Each type has its own benefits, which depends on the location where the concrete is to be installed.
Cast-in type
This style is most suited for the new construction or the retrofitted style where fresh concrete is poured. The warning tiles are embedded into the concrete once it fully sets.
Cast-in-place-Replaceable
This is very similar to the cast-in-type surface except for one major difference. The panels consist of two separate pieces so they could be changed or replaced without any hassle.
Surface-Applied
This is also a good option for new construction as well as retrofitted ones. The panels are placed on top of the existing concrete surface. It takes barely ten minutes to install the concrete detectable warning tiles.
Radius systems
This particular type of warning surface is curved so it could be used at turns or at curved areas where you would need a constant warning surface.
The features that you look for should meet the ADA requirements, fulfill the States ordinances if there are any, and they should fulfill the project's requirements.
