Concrete Grinding
Causes of Trip & Fall Hazards
Tree Roots, natural shifting or settling of ground, or concrete
replacement where previous level was not matched can be the
cause of a raised sidewalk or concrete pathway.
Solution
Concrete Grinding is a modern technique to eliminate trip and
fall hazards. The process uses a Scarifier Concrete Grinder
and Dry Surface Grinder to sand down the raised side of two
joining sections of concrete. Within a matter of minutes, the
raised side can be ground down permanently eliminating the "trip
and fall hazard".
Annual Reviews
All of our clients realize the importance of removing trip &
fall hazards. We help save them the headache and expense of
costly trip and fall litigation. Therefore as part of our services
we offer Annual Site Reviews.
Determine Work Needed
Safety Survey & Site Inspections
Before the first phase of the project, our staff will prepare a free Safety Survey and Site Inspection. This survey will define all sidewalk and concrete areaas that may cause a trip and fall incident, allowing you to determine what work you would like to complete.
Once you determine the work you would like us to complete, we can work within your schedule for the best time and date. Some of our clients request that the work be completed in a single day. Others spread the work over several months allowing the costs to easily work within their budgets. Whatever your need we will work with you for a solution.
concrete grinding specifications & stages
Grinding 1/4" - 2"
At the minimum, the scope of grinding shall be any vertical displacement in a path of travel of 1/4 inch or greater. At a maximum a 2 inch vertical displacement may be repaired by grinding. Over 2 inches must be repaired by replacement.
Scarifier Grind
For large grinds, the initial concrete removal will be performed using a scarifier with an attached vacuum to contain the generated concreted dust.
Smooth
Completed grinds shall be smooth and sloped back at a minimum of a 1:8 slope. An example would be a 1 inch vertical displacement will be sloped back at least 8 inches from the point of the lip. A 1/2 inch vertical displacement will be sloped back 4 inches
Dry Hand Grinder
Smaller grinds and finishing will be performed using a dry hand grinder. This also maintains an attached vacuum to contain the generated concreted dust. This fine grinding process allows our technicians to complete the work in visually pleasing finish.
Clean Visually Pleasing Look
The completed grind will be squared off at the back to allow for a clean look. The concrete on the other side of the grind should be left untouched. The finished surface will initially be lighter in color and the aggregate will show.
Finished Project
The finished grind will not be slippery. It will have about the same coefficient of friction as the undisturbed concrete surface.
