In the last two years, two polishing contractors—Service Resource of Nashville, Tenn., and VTI Contracting of Shelbyville, Ind.—have had to adapt to conditions no one had anticipated. Service Resource was called on to restore a concrete floor after a 100-year flood inundated Nashville and the Opry Mills Mall in May 2010. About the same time, an ordinary polishing job at a Walgreens in Greenwood, Ind., turned out to be anything but routine when workers discovered the slab they were going to polish was out of tolerance.

Bass Pro Shop

Few areas escaped damage when the skies opened and Nashville received more than 1 foot of rain in 2 days in May 2010. This included the Bass Pro Shop in Opry Mills Mall. The flood left 2 feet of water in the store by the time the rain ended and the nearby river subsided.

The project involved completely remediating the space before Service Resource began its work. Following the retailer’s specification, the contractor performed grinding, polishing, densifying, and dying using L.M. Scofield’s Formula One Polished Concrete System.

Any other floor surface is not capable of this type of restoration in such a timely manner. By choosing polished concrete for its floor, the retailer was able to reopen less than 5 months after the soaking. The last area of the mall to reopen did so in May 2012, more than 20 months after the Bass Pro Shop.


When staging its mockup on this project, VTI polishers learned that the floor did not meet flatness and levelness requirements. The result was that in trying to achieve a level surface, large aggregate was left exposed in some areas, but not in others.

Store officials were committed to a flat, polished concrete floor with a consistent appearance, so they provided VTI a change order requesting that the entire floor be ground to expose the large aggregate. This was followed by Prosoco LS/CS densifier and LS Guard.

Not all customers are as accommodating as Walgreens was for VTI, so it is important for a contractor to provide its personnel with the ability to counsel the customer at the jobsite. Every project supervisor must be trained to comfortably discuss the unexpected situations that do arise and be able to offer realistic options.

Finally, only accept written approvals for change orders, as they are the only documents that guarantee that you will receive payment for the changes.
