What Truncated Domes Are & Where They Are Used?

Truncated domes are designed to make public areas accessible and safe for those who are blind. These are mats that will alert blind people of difficulties ahead along their paths to their destinations. They should be installed on curb cuts, street intersections, transit platform edges, islands, track crossings, and cut-through medians.

The Beginning Of Truncated Domes

Also known as tactile paving, the beginning of truncated domes dates back to the 60s. The Japanese inventor, Seiichi Miyake, created Tenji blocks to help a friend who was visually impaired safely navigate train stations, stairs, and other public places. This also helped many other visually impaired people to get around safely.

Tenji blocks were the first form of truncated domes and served two major purposes. One of the designs was a series of lines and the lines signified that pedestrians were approaching a road that was safe. They were given the go-ahead to continue forward. The other design had truncated domes which meant they were entering an unsafe area such as the end of the boarding platform for trains or a sidewalk ending at a road.

The benefits from this invention led to this product becoming a huge success in just 3 years. Oklahoma City made it mandatory to have these domes in train stations. Other countries,  including Britain and Australia, adopted tactile paving in the 1990s.

Both the United States and Canada embraced the invention by making tactile paving a legal requirement.

What Truncated Domes Are

Truncated Domes are pavers created to be seen, felt, and heard by presenting a detectable warning for pedestrians, especially those who are visually impaired.

The warning systems are designed to make public places safer and more accessible. They come with wayfinding bars that will safely guide pedestrians to the next step along their way.  The pavers improve safety for everyone, regardless of their abilities.

Usually, truncated domes also called Cast in place truncated domes are either square or rectangular and have bumps on the surface. The bumps are often circular signifying “Stop” or rectangular signifying “Go”.

Truncated domes are made of heavy-duty polyurethane, ceramic, or concrete to ensure the substances are durable.

Various countries have their own unique requirements and standards. The standards determine the color, size, shape, and distribution of the bumps.

Even though they are very popular for safety, the bumps can also be challenging for those in wheelchairs and have been reported to be slippery. There have been several efforts to make truncated domes safer for use by everyone.

Why Do We Need Truncated Domes?

You might wonder what is so special about truncated domes. There are two major reasons for making these modern versions of the Tenji block worth investing in.

Truncated domes have a unique, discernible experience underfoot that does not require vision.

The standardized use of tactile pavers means there is consistency in warnings and offers the same level of safety regardless of the state or city you might visit. Just try to imagine what would happen if these installations were not standardized. It would possess a serious problem for those who are visually impaired.

On a whole, truncated domes can reflect sound, and help those with guidance canes to navigate public areas without assistance, and safety.

The ADA or Americans With Disabilities Act

In 1990, The Americans With Disabilities Act was adopted. This is a law that prohibits discrimination against disabled people and this applies to employment, movement, and accessibility in public.

There are different laws in existence that require the installment of tactile pavers in specific areas. The laws include the Public Right of Way Act,  ADA, along with California Title 24 requirements.

The ADA requires that all public spaces be accessible and that community members find it convenient and enjoyable when in these places. Most notably, the Act requires the use of truncated domes as visual and tactile warning systems for those who are visually impaired.

To bolster the ACT, the government introduced ADA standards. One section of the standards clearly states that truncated domes must be installed in spaces accessible by the public.

Some of these places include parking garages, stairs, escalators, wheelchair ramps, transit platforms, and pedestrian crossings.

There are  ADA  Accessibility Guidelines that clearly state the requirements for the installation of truncated domes. Some of the specifications include:


This section states that detectable warnings must include truncated domes aligned in square or radial grid patterns.

Dome Size

Truncated domes must have a diameter at the base between 23 mm (0.9 in) and 36 mm (1.4 in) at maximum. The top diameter must be 50% to 60% of the base diameter and its height must be 5 mm (0.2 in).

Dome Spacing

The center-to-center spacing of the truncated dome must be a minimum of 41 mm (1.6 in) and a maximum of 61 mm (2.4 in). The base spacing must be at least 17 mm (0.65 in).


The surface of the truncated dome must visually contrast the adjacent walkway surface, highway or street, or gutter.  We will go into this in further detail in another subheading.


A tactile paver's surface must extend at least 610 mm (24 in) and it should be going in the direction of travel.


What if the curb's ramp at the bottom grade break ends at 1.5 m (5.0 ft) or less from the curb's back? The truncated dome must be installed on the ramp surface at the grade break's bottom or installed on the lower landing. Landing and blended transitions are sections of sidewalk within standards allowing passage from one section to another. The truncated dome must be installed on the blended transition at the curb's back or landing.


The guidelines require that aligning the rows of truncated domes must be perpendicularly or radially to the grade break between the blended transition and the street, ramp, or landing.

Locations For Truncated Domes

Let's go into more detail about Truncated Domes locations. Here are other places requiring tactile surfaces:

Stairwell with Warning Pad

Curb Ramps

Curbs allow scooters, walkers, and wheelchairs to travel between sidewalks and streets safely. Visually impaired people can find it difficult to identify with these transitions. Therefore, truncated domes are required at the transitions between streets and sidewalks where curbs indicate crosswalks or someplace with a cut. Sidewalks tell blind or partially blind people they are moving traffic nearby or they are in a safe area.

Street Intersections

Curb cuts located at street intersections must have tactile pavers. Most local authorities install curb cuts at pedestrian crossings, easing access to building entrances and easing the transition to and from parking garages. They might install curb ramps and truncated domes at nearby crossings, depending on public facilities' availability, or people with mobility disabilities can suggest where they are needed.

Transit Platform Edges

If you don't know, ADA requires that all unguarded platform boarding edges have tactile pavers. The standards require panels that are at least 60.96 cm (24 in) wide on the platforms used by the public.

Although grooved lines are very common warning systems on transit platform edges, the lines are not as safe as truncated domes. Those who suffer from poor vision may not be able to recognize grooved lines.

On the other hand, truncated domes are easy to identify even underfoot through the soles of shoes. These tactile pavers are better at warning people to prevent them from falling onto train tracks.

Tracking Crossings

Tactile pavers are required on sidewalks that lead to track crossings. The pavers must be far enough away to alert people well ahead of time before their lives could be at risk. A distance of 1.83-4.57 m (6-15 ft) from the nearest rail's centerline is usually considered sufficient.

The distance leaves enough room for train gates to close, keeping people far enough away from passing trains.

Cut-Through Medians Or Islands

In general, raised islands at crossings must be level with the street or they can have curb cuts on both sides.

The direction of a curb cut's running slope must have a level of  48 in (121.92 cm) in length and 36 in (91.44 cm) in width. They must cut through or they can have curb cuts on both sides.

Note - Using truncated domes on steep slopes is not advised!

The Patterns On Tactile Paving

Tactile paver patterns often change, it depends on location. You could discover that the patterns will depend on the hazards that are present in a certain location. Different truncated dome patterns are sending different alerts for different dangerous risks.

Visual Contrast & What They Mean

In the ADA guidelines for installing truncated domes, there must be contrasts between the tactile paver's color and the adjacent area.

First off, the goal is to install truncated domes to offer a clear warning of hazards along the path ahead. They are designed to warn people by offering visual information. Pedestrians with visual issues could encounter challenges distinguishing between the tactile paving colors and the surroundings. In some cases, they may not pick up on a warning that is far ahead which could expose them to danger.

The ADA regulations require a light-on-dark or a dark-on-light for contrast purposes. Truncated domes must have a color that is totally opposite that of their surroundings. Pedestrians could miss out on a warning that is far ahead which could place them in harm's way because of the colors. The truncated domes must have a different color from that of the surrounding. A different, single color could provide better visual contrast.

How To Install Truncated Domes

Installing a truncated dome is actually quite simple and can be done pretty quickly.  That said, it will depend on the type of tile being used. The two most popular tiles are surface-mount tactile tiles and cast-in-place.

Cast-In-Place Tiles

Here are the steps for installing cast-in-place tiles:

Pour and then level the cement
Set the tile in place
Tamp down on the tile to remove air trapped underneath.
After the tile is in place, use a cinder block to weigh it down for 2 to 4 hours in order for the cement to set.

Surface-Mount Tiles

This option is easier than cast-in-place because you do not have to pour cement.  Here are the steps for installing surface-mount tiles

Make sure the surface is dry and free of moisture, debris, oil, and grease.
Apply the adhesive to the tile's underside.
Place the tile in the installation area.
After you have placed the tile in the correct location, drill holes in the cement at the fastener locations.
Hammer the fasteners into place then seal the tile's edge with caulk.

In Conclusion

Truncated domes are created to make public areas safer and accessible to everyone, especially those with visual impairments. The pavers offer tactile feedback by alerting pedestrians of dangers on the path.

These pavers are so critical that Federal State laws recognize their value. ADA standards state the minimum requirements that tactile pavers must meet and where they must be installed. In many cases, they are required for the following:

Curb ramps
The edges of transit platforms
Track crossing
Island or cut-through medians
