Concrete Ramps Truncated Dome

A concrete ramps truncated dome is a small, flattened dome that provides a surface that is distinguishable underfoot and by cane, and they are closely spaced so that pedestrians can maintain stability. In addition, the color of the domes contrasts with the surrounding pedestrian ramp to provide a cue for low-vision persons that a transition from the pedestrian area to the vehicular area is forthcoming.

Since 1991, truncated domes have been the standard design requirement for detectable warnings on curb ramps and at flush transitions from sidewalks to street crossings. The U.S. Access Board temporarily suspended the standard in 1994 but allowed the suspension to expire in 2001, reestablishing the mandate.

Armor-Tile tactile detectable warning systems manufactures the best concrete ramps truncated dome by utilizing state of the art materials.  Vitrified Polymer Composite (VPC) with an Aluminum Oxide additive is impregnated into many layers of Fiberglass creating the most durable, easy to install detectable warning tile available on the market.  If you are interested in learning more about ADA requirements,  detectable warning applications and installation of a concrete ramps truncated dome, goto  www.armor-tile.com to learn this and much more about the what, why and where of detectable warnings.
