Armor Tile Detectable Warning Surfacing

Surface-applied truncated dome tiles are the best way to adapt any area to bring in a detectable warning system for added safety and greater navigation.

You've likely seen installed warning systems in various areas such as crosswalks, on train platforms, or while approaching an escalator. Known as tactile walking surface indicators (TWSI), or Detectable Warning Surfaces (DWS).

These pads are made with domes, or wayfinding bar tiles and barely stick out of the ground. They provide sound and tactile feel when underfoot, or touched with a cane. Truncated domes offer additional feedback of nearby hazards for those who are visually impaired.

Why We Need Detectable Warning Systems?

Detectable warning systems are required by the Americans with Disabilities Act (ADA ) and play an important role in public safety. These systems are designed to create a safe area for pedestrians, so everyone can easily navigate without needing help from others. The truncated domes offer a non-visual warning for possible hazards ahead.

Detectable warning systems are made of wayfinding bars and truncated domes that are easily detected underfoot or using a guidance cane. The surfaces are raised to provide a non-visual indication of changes in a walkway but also make it easier to follow a path allowing people of all abilities to navigate any space.

Detectable warning systems are extremely helpful to accomplish the following:

  • Create a safe and easy way to navigate space
  • Provide non-visual alerts
  • Warn of any changing conditions

How Do Detectable Warnings Make Transit Safer?

These systems are especially helpful for people who suffer from low to no vision as well as helping people of all abilities within a transit facility.

Tactile walking surface indicators will help guide pedestrians to the right platform thanks to their simple contrast to the surrounding area which will draw pedestrians' attention.

In low light areas, tactile warning systems can serve as a path-marking, or wayfinding system because the truncated domes offer an easily detectable path. Not only are truncated dome tiles great for path-marking but also serve as non-visual warnings. The domes will alert pedestrians about any changes in the path up ahead.

For those without visual impairments, feeling the dome tiles underfoot can communicate to pedestrians to stop and look around the area for any hazards before moving forward. These systems are also very important in transit facilities. They will alert the public of drop-offs at the edge of the train or subway platforms. 

Why Detectable Warnings Are Important in Transit Facilities

Transit facilities can be difficult to navigate for the visually impaired, especially in areas that have curb ramps. Due to the dangerous drop-offs at train and subway platforms, detectable warnings are critical to maintaining the safety of transit facilities.

The use of ramps was initially used to help people in wheelchairs to navigate and access public spaces and to board public trains.

The slope between the sidewalk and curb ramps made it very difficult for the visually impaired to get around public areas due to the fact that the slopes between the ramps and walkways are difficult to detect.

How are Armor Tile Warning Surfaces Used at Transit Facilities

When construction of the new transit facility started, the installation of the detectable warning system was taken into consideration. Casting in place truncated dome tiles might be the best ADA tiles for new construction. The detectable warning pads can be directly set in wet concrete forming a long-lasting installation.

Armor-Tile being displayed outside the Flagship Amazon Fresh Store

Amazon Fresh Opening

During the event, a few customers got the opportunity to view the Woodland Hills’ new grocery store, Amazon Fresh. Thanks to new technology.

Surrounding the store’s entryway is Armor-Tile® surface applied detectable warning tiles. These tiles have been created to allow the public more accessible entry for those with visual impairments. According to John Heffner, Vice President of Armor-Tile®, it’s encouraging to see large companies are taking the right approach for accessibility.

The surface of these tiles offers state and federal mandated truncated domes that are just large enough to offer tactile warnings, while promoting pedestrian safety. 

The truncated domes will alert a person with visual impairments they are approaching the entrance to the store or entering the parking lot when leaving the store. These detectable warning tiles will be felt underfoot by offering a distinct palpable difference between the surrounding pavement and the tile.

Also, when tapped by a guidance cane, the truncated domes will send off an audible warning which is a unique sound letting the person know there is a change in the walking surface.

These tiles are installed at curb ramps, pedestrian crossings, transit platforms, parking areas, and at Amazon Fresh. John Heffner said they are very proud to have their product featured at the new Amazon Fresh store and excited to have this new addition to their community.

If you have a new store or revamping your current store, you need better accessibility. You should seriously consider looking into Armor-Tile® surface applied detectable warning tiles for added safety and better accessibility.

How Truncated Domes Came About

In 1965, creator and inventor Seiichi Miyake came up with a design that is now used in almost every country in the world. He wanted to help a friend and spent his own money to create what were known at that time as Tenji blocks. Since that time, truncated domes became the perfect warning surface system built-into sidewalks and pedestrian thoroughfares. These domes are installed throughout many countries including Japan, Australia, the United Kingdom, Canada, and the United States. Originally, the design was a series of lines that indicated if someone was traveling along the path, and should continue to move forward.

The second design consisted of truncated domes that would indicate a pedestrian should stop because of a change in the direction of the sidewalk to a motorway or they were reaching the area for the train boarding platforms and should wait for the train to stop.

The first place for the design was placed on a street in Okayama City, Japan which was located nearby the Okayama School for the Blind. Ten years later, these domes became a mandatory requirement for the Japanese National Railways.

Since that time, the U.S enacted the ADA and truncated domes became mandatory on all sidewalks, all train stations, and for public thoroughfares that coincide with automobile traffic. The lined tiles are not required in the U.S but the textured tiles are required everywhere else. In Japan, the lined tiles indicate “Go”, while the textured tiles indicate “Stop”.

When Did Truncated Domes Become A Part Of The Construction World In The US?

In 2010, both the Federal Code and the State of California Building Code were changed. State requirements clearly specified that while the diameter of the base must be 0.9 inches, the top diameter must be 0.45 inches. As of 1991, ADA guidelines required that domes have a theoretical 0.9-inch diameter, 0.2-inch height, and 2.35-inch center-to-center spacing.

As of date, California requires that while the base diameter must be 0.9-inches, the top diameter must be 0.45-inches. Recently, the Federal Code stated there must be a 0.65-inch minimum base to base spacing between the adjacent domes. This is in addition to the existing center-to-center spacing requirements already in place. Also, the 2010 CBC change required truncated dome sections must occupy the entire length and width of a curb ramp, doubling the amount of panels now required.
