FREQUENTLY ASKED QUESTIONS
Detectable warning tiles and requirements
Does ADA Solutions meet ADA, ADAAG, and PROWAG requirements?
Yes. Since the mid 1980’s ADA Solutions has been manufacturing the highest-quality detectable warning products in the world. All of ADA Solution’s products adhere to ADAAG and PROWAG requirements.
What size detectable warnings are required by the Americans with Disabilities Act Accessibility Guidelines (ADAAG)?
The current guideline requires the detectable warning surface to begin 6” to 8” from the back of the curb extending 24” or 2 feet in the direction of travel. To learn more about the various regulations related to detectable warning surfaces please visit our Government Regulations Page, or call us anytime at (800) 372-0519.
What are detectable warning tiles made of?
ADA Solution’s uses the most advanced homogenous glass and carbon reinforced composite to create a colorfast and U.V. stable product. Each truncated dome is fiberglass reinforced for enhanced durability. The color is uniform throughout, and does not rely on a surface coating (paint) to achieve color stability.
Should reinforcing bar be installed through the holes in the sides of the cast-in-place product?
No. The larger holes in the sides of the embedment flanges of the cast-in-place product are designed to let concrete flow through to securely anchor the product in the fresh concrete.
What is needed to install the surface mounted detectable warning tiles?
Fasteners and adhesive are included with each tile. Purchase a quality sealant (Sonneborn NP1 or equivalent) to seal the entire perimeter of installed tactile to finish the installation.
Where can I find installation instructions?
ADA Solution’s brochure contains detailed installation instructions for all of our detectable warning systems. Ask your local distributor or call (800) 372-0519 to request a brochure.
The following detailed instructions are also available for download:
What are the dome spacing dimensions of ADA Solution’s detectable warnings?
ADA Solutions is the only detectable warning manufacturer to offer both 1.67” and 2.35” center to center spacing. Please call (800) 372-0519 to discuss available sizes, colors and dome spacing.
What is the height of the truncated dome in ADA Solution’s detectable warning products?
ADA Solution’s manufactures all of our truncated domes to measure .20”

Are custom colors available?
Yes. ADA Solutions manufactures custom colors. Please call us at (800)372-0519 to discuss your custom color needs.
Does temperature affect ADA Solution’s products?

For additional information refer to our Product Test Data
Will salt from snow removal affect ADA Solution’s detectable warning tiles?
No. Lab testing shows that salt will not affect the composite material used to manufacture ADA Solution’s detectable warning tiles. In fact, chewing gum and even spray paint can be removed without staining ADA Solution’s detectable warning tiles.
Can ADA Solution’s surface mounted tile be mounted on asphalt?
No. Due to the instability of the asphalt surface we do not recommend it for the application of surface mounted detectable warning tiles. For a long term solution, we recommend pouring a concrete footer and installing ADA Solution’s cast-in-place or replaceable cast-in-place system.
What does “sound on cane “mean?
“Sound on cane” is an important element of ADA Solution’s detectable warning tile design. The visually impaired, and blind, rely on audible cues from their cane as they sweep it in front of them. ADA Solution’s composite material and proven design features enhance sound attenuation making them the best choice for true detectability.
Can I cut ADA Solution’s detectable warning tiles? If so, does it affect the warranty?
ADA Solution’s cast-in-place, retrofit, and radius systems can be cut in the field. Use a continuous rim diamond blade or a 32 tooth carbide tip blade to cut the tiles. We do not recommend cutting the straight replaceable tiles. Please call (800)372-0519 for more information.
Where can I purchase ADA Solution’s detectable warning?

When cutting a retrofit tile I cut off the preformed fastener dome. What should I do?
Use a half-inch countersink bit to create a recess in any of the existing truncated domes. Install the fastener as provided. Please call (800)372-0519 with any questions.
I need to install 200’ of continuous retrofit detectable warning tiles. What about the bevel?
We recommend cutting the bevel off and measure to keep the domes properly spaced. Then simply caulk the joint between the tiles.
Please call (800)372-0519 to speak with speak with an experienced professional.
I need to install 300’ of continuous replaceable detectable warning tiles. Should I space them?
Installation of successive replaceable tactile units requires specific installation procedures. Please read through our Replaceable Installation Instructions or call (800)372-0519 with any questions.
Does temperature affect the installation of the surface mounted tile?
Yes. The adhesive requires temperatures of 30 degrees F and rising to allow for proper curing.
Which ADA Solution’s detectable warning system should I use for my project?
For new construction we recommend the cast-in-place, or cast-in-place replaceable systems. The cast-in-place and cast-in-place replaceable systems allow for an earlier completion date – saving you time and money. The surface mounted system is used to retrofit existing concrete ramps.
Please call (800)372-0519 to discuss the best detectable warning solution for your current and future jobs.
What tools are required to install the cast-in-place systems?
You will require a rubber mallet, as well as edging and finishing tools. Also, a razor knife for removing the plastic protective covering after installation. Please read through our Cast-In-Place Installation Instructions or call (800)372-0519 with any questions.
