ADA Detectable Warning Surfaces and Concrete Tactiles

What is a Detectable Warning Surface?  What kind of concrete is needed for Tactile replacement in Oregon (see below)?

The primary purpose of a cross-walk at an intersection for the the safety of the pedestrian.  Yet, many accidents occur in the cross-walk involving pedestrians, cyclists and automobiles.

Too address the major issue involving cross-walk accidents, an innovative solution is taking hold across our communities by using a concrete tactile.

The concrete tactile is a cast-in-place product offered by many companies that is essentially a Detectable Warning Surface used to ALERT individuals of the dangers.  Often times these tactile surfaces are placed at intersections, and cross-walks.

ADA Pads are another term used to describe the Detectable Warning Surface.

What Is a Curb Ramp?  A curb ramp is a short ramp cutting through a curb or built up to it.  If designed and constructed to be accessible, a curb ramp provides an accessible route that people with disabilities can use to safely transition from a roadway to a curbed sidewalk and vice versa. – via ADA Tool Kit

What kind of Concrete is needed for Tactile Replacement in Oregon and the Portland Metro? Volume Concrete LLC., delivers a 4,000psi mix that adheres to the local building codes and requirements.  This specific mix design is dialed specifically for the Detectable Warning Surface and ADA Tactile, allowing for an easier install without compromising strength or workability.

Please contact our Cell Phone Dispatch (971)219-8604 and we can assist in getting the right design for that next project!

Note:   Each City, County and State have specific requirements regarding the concrete mix design, and it is important to do due diligence in researching those community-specific requirements.

The ADA Standards require that curb ramps include features called “detectable warnings.” Detectable warnings consist of a series of small domes that contrast in color with the surrounding sidewalk or street. They must be integrated into the walking surface, and there are specific measurements for the size and spacing of the domes. – via ADA Tool Kit
