Sidewalk Trip Hazard Removal

Diamond Coring provides concrete grinding and maintenance services to help you avoid a liability case and to ensure you comply with Federal Law to remove all trip hazards from sidewalks and pedestrian walkways. The Americans with Disabilities Act (ADA) defines a trip hazard as any vertical change of 1/4" or more at a joint or crack in a walkway surface.

Summary of ADA Accessibility Guidelines

4.5 Ground and Floor Surfaces.


4.5.1* General. Ground and floor surfaces along accessible routes and in accessible rooms and spaces including floors, walks, ramps, stairs, and curb ramps, shall be stable, firm, slip-resistant, and shall comply with 4.5.


4.5.2 Changes in Level. Changes in level up to 1/4 in (6 mm) may be vertical and without edge treatment. Changes in level between 1/4 in and 1/2 in (6 mm and 13 mm) shall be beveled with a slope no greater than 1:2. Changes in level greater than 1/2 in (13 mm) shall be accomplished by means of a ramp that complies with 4.7 or 4.8.


If you are a Property Manager, Municipality, School District, or Home Owner's Association, you can easily reduce your financial liability associated with trip-related pedestrian injuries by understanding how hazards occur and what preventative measures are available to you.

Common Causes of Trip Hazards

Changes in sidewalk elevation occur due to such occurrences as:


  • Tree roots pushing upwards

  • Heaving and settling due to frost

  • Buckling due to displacement of sub base


Such changes in elevation can cause major problems and result in serious injuries that affect:


  • Pedestrians with mobility impairments: difficulty lifting feet, or crutches which can cause trips and falls

  • Pedestrians with visibility impairments: difficulty detecting changes in elevation which can cause trips and falls

  • Pedestrians with wheel chairs or wheel chair riders: difficulty with or inability to roll over steep changes in elevation


Work with a company that has the experience and expertise to ensure you comply with Federal Law and protect your assets.
