Situated atop a high hill at the end of Daisy Lane, a new business development site was taking shape. To access this hilltop site, the existing Daisy Lane would need to extend up the hill to reach the future Summit Spring development.

Five large retaining walls were needed along the extended roadway to relieve concern on the overall stability of the on-site slope. The civil consultants identified Redi-Rock as the right block system for the job, which lead the manufacturers at Redi-Rock K.I.T. to call upon our engineering team to provide geo-structural analysis and design construction drawings.

Our team designed three of the walls as Gravity structures: Retaining wall structures that rely on sheer mass of the block units for stability. The other two walls were designed as Positive Connection (PC) structures and utilize 12-inch-wide strips of geogrid reinforcement to provide necessary external stability due to the tall wall heights.

Geotechnical data showed the walls would be installed on top of competent bedrock, allowing our design team to optimize 20-feet-tall PC sections with nothing but 28” Redi-Rock units.

The final scope of construction surpassed 20,000 square-feet of Redi-Rock wall-face, with maximum wall heights of 22.5 feet.

Redi-Rock precast retaining wall units were manufactured by Redi-Rock K.I.T.
