In the fall of 2015, plans were prepared for a new Dollar General store off Hwy 51 S in Hernando. The site plan for the store called for a retaining wall with a 4-foot maximum exposed height along the property line. The retaining wall would need to be constructed within five feet of the property line with no construction easement on the neighboring property.

Based upon the successful use of the Redi-Rock system on other projects, Rozier Construction, the contractor, called on MMC Materials to inquire if Redi-Rock could provide an economical solution for the structure. MMC quickly engaged JC Hines & Associates to prepare the necessary preliminary designs for cost estimating. Once accurate material quantities were determined, the contractor concluded that Redi-Rock would meet the project budget requirements and the design team at JC Hines & Associates was released to prepare final construction drawings.

The final Redi-Rock wall design utilized 41-inch blocks on the bottom course that transitioned to 28-inch block units for the rest of the wall. A 12-inch zone of No.57 crushed stone fill was placed immediately behind the wall to allow for proper drainage of the wall system. The retaining wall units and imported backfill were installed within the five feet allowance to the property line.

The total face area of the wall is 974 square-feet, and the natural gray cobblestone Redi-Rock units were manufactured by MMC Materials in Jackson, MS.
