For your convenience, we have compiled the top frequently asked questions, regarding our detectable warning systems, in this FAQ. Questions regarding ADA requirements, truncated domes, and installation are all answered here. If you have any questions our FAQ cannot answer, visit our Contact page and we will send you a detailed personal reply. We hope to hear from you soon. 

How much does each detectable warning tile weigh? 

Our tactile walking surface indicators (TWSI) are lightweight weighing approximately 3lbs per square foot. 

What are your detectable warning surfaces made of? 

Each tactile paving ADA compliant tile is manufactured from engineered composite polymers which provide superior durability as well as slip resistance, corrosion resistance, and abrasion resistance.

These materials are used in both our wayfinding bars and truncated domes. 

Where can I find installation instructions for the different detectable warning surfaces? 

Installation instructions for each ADA tile can be found in the Installation and Maintenance Instructions page>  

Does Access® Tile meet the ADA / California Title 24 Requirements? 

Yes! Access® Tile detectable warning plates are specifically designed and rigorously tested, to meet and exceed the ADA and California Title 24 requirements. Each Detectable Warning Tile has a truncated dome spacing of 2.35” and height of 0.20”. They are tested using the AASHTO HS20-44 wheel load test, as well as the ASTM Concrete tests, and the ASTM D tests. 

Is Access® Tile available in different colors? 

Each detectable warning paver is available in ten standard colors. These colors are Orchre Yellow (23594), Federal Yellow (33538), Safety Red (31350), Colonial Red (20109), Brick Red (22144), Ocean Blue (15187), Bright White (27925), Light Gray(26280), Dark Grey (36118), and Onyx Black (17038). 

Can Access® Tile’s ADA compliant tiles withstand harsh winters? 

Access® Tile’s ADA warning mats are manufactured to be non-porous, protecting against water absorption during freeze-thaw cycles in winter months. Our ADA compliant tiles can withstand all temperature and climate fluctuations associated with winter. 

How does salt affect Access® Tile Products? 

Salt will not affect our tactile warning surfaces. Extensive testing has confirmed salt, chewing gum, and aerosol paint can be removed with cleaning solutions – contact us to learn more. 

Can your detectable warning tiles be embedded in asphalt? 

It is not recommended our detectable warning surfaces be installed in asphalt. The recommended solution, however, is to cut a small square of asphalt, pour concrete, and then embed the Access® Tile in the wet set concrete. 

What is the smallest tile that still meets the ADA Accessibility Guidelines (ADAAG)? 

The latest draft of the ADAAG specifies tactile paving ADA compliant tiles begin 6” to 8” from the curb line, generally at the back of the curb, and extend 2’ in the direction of travel on the curb ramp. The width of the detectable warning tiles is specified to extend the width of the flat portion of the curb ramp. Please refer to the guidelines for all requirements specified by the ADAAG. 

Are Access® Tile products under warranty? 

All of our replaceable detectable warning panels come with a 5-year warranty, starting from the date of sale. This written guarantee protects your ADA tiles against manufacturer’s defects, defective work, breakage, deformation. 

Does cutting Access® Tile affect the warranty? 

Cutting any of our detectable warning products does not void the warranty. All Access® Tile replaceable TWSI can be cut to custom sizes, or in a radius, using a continuous rim diamond blade in a circular saw or mini-grinder. The use of a straight edge to guide your cuts is recommended, when appropriate. 

What are the standard sizes of ADA warning mats? 

Normal sizes for our Tactile Walking Surface Indicators are (Length x Width): 12″x12″, 24″x24″, 24” x 36”, 24” x 48”, 24” x 60”, 36” x 48”, 36” x 60” and radius. 

When should I use Replaceable Cast in Place tiles vs. Surface Applied Tiles? 

Replaceable Cast in Place tiles are installed directly into wet set concrete and require less labor time to install. This makes them the more economic option of the two. Surface Applied tiles can be retrofitted into any existing concrete structure using a series of anchors, fasteners, and adhesive. 

What tools do I need to install Access® Tile? 

Access® Tile is extremely easy to install and replace. Required tools include standard masonry tools, a non-marring rubber mallet, and a ¼” radius finishing tool. These tools allow for a safe and easy install of any of our detectable warning pavers. For more information, or to download our installation instructions, please see our Installation and Maintenance page. 

What tool is required to remove the tamper-resistant fasteners? 

Stainless-steel tamper resistant fasteners can be removed with a special bit called a T-27 Pin and Torx.  

How long does it take to install your ADA warning tiles? 

All of our ADA compliant tiles can be installed in minutes and are designed to be lightweight and easy to handle. 

How do snowplows affect detectable warning tiles? 

If snowplows have shoes on their blades or use brushes, then no damage will occur. For areas that are heavily plowed, please refer to Cast Iron Detectable Warning Plates. 

Is Access® Tile American made? 

Yes, all of our detectable warning products are designed and manufactured in the USA.
