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.
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.
The Specification of Honed or Polished Concrete Finishes. 1 Description anD scope. Honing gives concrete a smooth matt finish by grinding the concrete surface and exposing the aggregates. Smoother polished concrete surfaces can be achieved through extended honing using progressively finer abrasives finer grinding grit headspads to impart a lustre to the concrete surface.
At the minimum the scope of grinding shall be any vertical displacement in a path of travel of 14 inch or greater. At a maximum a 2 inch vertical displacement may be repaired by grinding. Over 2 inches must be repaired by replacement.
by Kristin Dispenza CSIInstalled in applications ranging from warehouses retail and residential settings polished concrete floors are no longer a novelty. They are economical durable and aesthetically appealing and have come into standard use over the past few years. However what has not become standard is a set of unified terms or policies to aid in the specification and communication between contractors architects and building owners.
The absence of a unified set of terms and policies has an impact beyond ease of communication. It can have adverse consequences with regard to the equipment andor processes used to construct a floor in the field and ultimately with how the quality of the finished floor is measured.
A Level 3 finished gloss was achieved on the floor of the Joe Cooper Ford car dealership in Tulsa Oklahoma. Photo courtesy Ardor Solutions Inc.With the establishment of these standardized definitions contractors owners and architects can communicate more clearly about the desired surface and necessary processes said Brad Burns CPAAs executive director. The result will be a higher quality end product. Through the development of position papers CPAA seeks to establish industry guidelines while demanding higher and more consistent quality from those in our industry.
Sep 09 2013nbsp018332The association defines hybrid polished concrete as a multi-step operationusing either standard grindingpolishing equipment lightweight equipment high-speed burnishing equipment or a combinationto combine the mechanical grinding honing and polishing process with the friction rubbing process by employing bonded abrasives abrasive .
Burns points out the driving force behind these initiatives are to give architects and designers the tools they need to specify product rather than a process.
There are more than 50 terms and definitions commonly used with processed and polished concrete including 12 introduced earlier this year.1 The new terms range from a basic definition of polished concrete to information more technically sophisticated. The tables included in the article include classifying aggregate exposures and finish gloss level information Figure 1.
As part of its core mission CPAA continues to develop standards and guidelines for the concrete polishing industry. Its next initiative will be to further develop testing methods for polished concrete.
Burns explains the intention is to create a test method to meet the criteria outlines in the definitions so the design goals can be achieved with quality products.
New polishing industry termsCPAA defines polished concrete as
the act of changing a concrete floor surface with or without aggregate exposure to achieve a specified level of gloss using one of the listed classifications Bonded Abrasive Polished Concrete Burnished Polished Concrete or Hybrid Polished Concrete.2

Polished Concrete Profiles How to Achieve Different Levels of SheenTime 0353Compare the four classes of aggregate exposure and three levels of gloss outlined by the Concrete Polishing Association of America.
At a level 3 polish your concrete floors will really begin toshine and clearly reflect side and overhead lighting.
Depending on the diamond grit you use to polish a concrete floor you can achieve different ranges of aggregate exposure and different levels of sheen from matte to a glassy mirror-like finish. The Concrete Polishing Council classifies finished gloss levels in ranges from 1 through 4 and aggregate exposures as A B C or D depending on the degree of exposure.
For coarse grinding youll generally start out using diamonds embedded in a metal matrix. As you begin to polish the floor in successive passes youll typically switch to finer diamond abrasives bonded in a plastic or resinous matrix to achieve higher degrees of shine.
