======================================================

Question:  “I have some trip hazards on my driveway. There are 5 sections that are raised about 1″ X 6 feet long. In your  honest opinion, do you think I could even these out with the Jepson 4.5″ Grinder kit? Thank you for being honest with me.”

ANSWER:    Based on the limited information in your question, and not actually seeing the Driveway condition, I would say the 4.5″ Grinding Cup would take a longer time than you are going to be willing to spend. I personally would not hesitate to use the much more powerful 7″ Makita Angle Grinder/Sander and the 7″ Grizzly Diamond Cup along with the Dust Muzzle and suitable Dust collection Shop Vacuum to grind the edges provided that it is as you described it. I expect that, if the sections are all in good condition, without cracks, etc., you may want to consider Slab-Jacking as a method to get the sections reasonably close to being even and then using the Jepson Grinder Kit or the Makita Grinder for finishing the job and for periodic maintenance grinding.

Now, More Questions in order to refine the answer:   Are the sections uniformly offset 1″ ? Did you actually measure the Step? Is 1″ the worst step? Any Larger? A 1″ Stub Toe Trip Hazard would require that you grind a progressive 12″ long ramp if you wanted to comply with Access Board Standards (which are not really applicable to your driveway). You can check in our Manual which is at the top of our web site and then calculate and mark the actual length of ramps that you would be grinding. Again, not having seen your driveway, I would offer the following comments. The sections that you grind will be rather white in color with the aggregate (stone) showing through and looking quite nice, but different from the rest of the driveway. Power-washing will clean up the un-ground sections but they will get dirty faster than the freshly ground sections. For a more uniform color over the entire Driveway, you could use the Makita Grinder to take a Skim cut over the entire driveway. I recently did this on my patio (27′ x 15′) where I had previously ground the Stub Toe Trip Hazards but wanted a nice uniform smooth surface over the entire patio and the adjoining sidewalk. This flat grinding was a wonderful application for the Makita 7″/9″ Grinder, my 7″ Grizzly Diamond Cup, the 8″ Dust Muzzle, and my Dust collection Shop Vacuum with its triple filtration system.I hope this helps.    Now, it’s time to:  Grind It. Cut It. Fix It.Sidewalker

Concrete Contractors:

The Grinding operations are being performed by Contractors who see the Grinding operation as a kind of “Clean Up” operation to make the new sections they install blend in with and flow smoothly into the existing sidewalk panels.  Contractors also use the Grinding operation as a method to win the jobs by offering a Hybrid Repair that incorporates replacement where absolutely necessary and grinding where appropriate. 

Maintenance Departments:

Many public and private institutions have “in-house” maintenance departments to do the actual work. A Hotel Chain or shopping center could easily justify having the complete sets of Sidewalk Savers equipment on their Trucks or in their workshops. Hospitals, schools, Parks on the city, state, National level, Office Parks, even the local Law offices who want to protect themselves from themselves, all have a need to be prepared to take corrective actions to maintain their property as a safe hazard free environment.

DIY Homeowners:

There are many cases where home owners or small businesses have relatively slight stub-toe trip-hazards that need to be addressed but which do not represent enough business to attract contractors who are unable to justify the cost of setting up their equipment for the relatively small amount of work.

Sidewalk Saver Entrepreneurs:

More recently, there have been increases in people who see the Sidewalk Saver Procedures as business opportunities to fill a void where none of the above seems to fit. Regardless of the category or the goals of the particular group, the need is huge. It is spread all over the country. It will continue to need to be done wherever trees grow or freeze-thaw conditions exist or wherever ground settles. And, best of all, the workpieces can never be shipped off shore to have the grinding operations performed.

Now, by applying the methods used for many years in California and cities like Portland, Oregon,  mid-west cities such as Columbus, OH have approved this process for at least some of the observed problems.

The benefits to cities and neighborhoods are the elimination of problems while they are small by simple periodic grinding.  Some politicians refer to this as the “Broken Window” theory – take care of the small problems and the big problems will take care of themselves.

Even the relatively steep step shown below can be made safer with a grinding operation on the left side of the raised block, although this would clearly be a temporary solution as the codes and procedures in many cities would require blocks such as these to be removed and replaced.

The Sidewalk below shows multiple trip hazards caused by a single, relatively small  tree.  In order to repair this type of a hazard, the costs would be the replacement costs for 3 perfectly good concrete sidewalk blocks.     Of course, the tree will keep growing so that in 2 or 3 years the new blocks would need to be replaced again.

Rather than waiting for the problem to get worse over time, diamond cup grinding for these blocks would require a minimal amount of work and would eliminate the Stub-Toe Trip Hazard liability for a fraction of the costs, providing a temporary reprieve for the same 2 - 3 years when additional grinding could perhaps be used or not, according to conditions and local codes.

Some of these Trip Hazards, such as the one at the top of the set of Stairs shown below, are so great that a Diamond Saw or Slab Jacking would be required to eliminate the hazard with grinding being used for fine-tuning the concrete and smoothing it out at the end of the job or for future preventative maintenance.

The following close-up picture of the Curb at the bottom of the Stairway shows how it is necessary to step up from the sidewalk to the curb and then to step down from the curb to the street.

Wouldn’t it be better and lower in cost for the State Park Lodge to simply eliminate the Trip Hazard rather than creating this wonderful artwork?

Especially since our cities in Ohio are spending tax dollars to install wheel chair ramps and requiring us to eliminate stub toe hazards on our residential sidewalks.

It does make one wonder how the City Sidewalk Police would react to residents putting yellow paint on the stub-toe trip hazards in front of their houses.  Or perhaps on the curbs which are elevated above the level of the sidewalks?     It really is not worth the effort to find out when it is so easy to simply:

Grind It!  Cut It!  and  Fix it!

Don’t Paint it!   Eliminate that Hazard.

Here we can see an area where many hazards have been eliminated by grinding.   It is amazing to think of how many skinned and bloody young knees were avoided by this simple 20 minute correction over the past year!     The only loser in this case is the Band-Aid Business!

A pickup truck, a wagon, and a few thousand dollars worth of equipment would be enough to get started saving public walkways and park sidewalks from the threats of stub-toe trip hazard liability.    

Whether it is done by the cities themselves or by sub-contracted service providers, the ongoing maintenance is readily accomplished at a fraction of the costs of removal and replacement.      What other business offers an endless supply of fixed location workpieces to be repaired by such a simple procedure as diamond grinding?      Isn’t it time for states, counties, and cities to demand that the hazards be eliminated rather than painted with “alert orange” paint?

Imagine that some person trips on a Stub-Toe Hazard in front of your house.  During the ensuing law suit, imagine the victim’s lawyer telling the jury that the sidewalk could have been rendered safe for an expense of $50.00 but that the owner chose to keep his $50.00 and to allow the hazard to wait for an unwitting victim.

Hmmmmm,  $50.00 worth of routine maintenance to avoid a settlement of $50,000.   Meanwhile, the pictures of the victim with his arm in a sling and his upcoming knee replacement surgery remind the jury of the very real medical costs and suffering caused by the Trip Hazard.     Does the word Negligence come to mind?
