Substation Slope Armoring

The design team for a substation expansion needed a solution for slope erosion around a substation in a desert area. The engineers required a product that could withstand the arid environment and stop slope erosion during heavy rain events. Erosion on the slopes surrounding the substation would lead to sediment deposition within the transformers, a risk that had to be permanently mitigated.

The concrete block mat, Flexamat® 10-NW, was selected to armor the slopes surrounding the substation. Motz Enterprises, Inc. supplied 310 custom length rolls. The tied concrete block mat rolls were pre-cut in custom lengths at the manufacturing plant. The concrete mat lengths matched the slope lengths onsite. Each roll was marked with it's designated number and roll size. Motz Enterprises coordinated the deliveries with the contractor so that the concrete mats arrived in the sequence of installation.
