the new leader in detectable warnings

The New Standard in Detectable Warnings

Detectile was founded on a simple premise: to manufacture the highest quality ADA compliant detectable warning products at a cost-effective price.  Detectile is committed to providing  durable, easy-to-install and competitively price truncated domes for the visually impaired and engineers our products to the highest standards.

Our Duratek tiles are one of the most durable detectable warning products on the market and have been field tested in some of the toughest condition and our Slimtek tiles are a budget friendly detectable warning solution that provide excellent performance for the price.  The replaceable design of our traditional Duratek and Slimtek product lines makes them easy to install and cost-effective to replace.   Try Detectiles for your next project and find out why Detectiles are the new standard in detectable warnings.

All Detectile products comply with ADAAG proposed standards and use the preferred truncated domes design to maximize detectability. Detectiles are the quick, easy, and cost effective solution to all of your detectable warning needs.

The History of Detectable Warnings and Truncated Domes

Detectable warnings are an Americans with Disabilities Act (ADA) requirement in the current Americans with Disabilities Act Accessibility Guidelines (ADAAG) for the use of detecting the boundary between the sidewalk and the street. In response to the requirements of the Americans with Disabilities Act (1990) curb ramps became a requirement between sidewalks and streets.  Unfortunately, the emergence of curb ramps led to a new problem it removed a visual cue for the end of sidewalks and made it more difficult for the the visually impaired to locate the boundary between the street and sidewalk. The answer to this new problem was the emergence of detectable warnings with truncated domes, which are now required by the ADA

The Access Board is currently finalizing  new ADAAG guidelines  (see,  for public rights-of-way that will address various detectable warning issues.  The new guidelines will cover pedestrian access to sidewalks and streets, including crosswalks, curb ramps, street furnishings, pedestrian signals, parking, and other components of public rights-of-way.  To find out more about detectable warnings check out our various articles and check back soon for our new blog.
