Successful erosion repair should include the implementation of erosion control measures to prevent future issues. The Dragonfly Pond Works Team has encountered a variety of erosion issues that were previously repaired improperly and erosion quickly occurred again as a result.
The Dragonfly Team recently assessed a badly eroded primary and secondary spillway in a Raleigh community. Spillways assist with water regulation and overflow. The spillways were located behind the dam of the community pond. They had been repaired improperly by a contractor a few years ago. The inadequate repairs caused the spillways to fail and erode again. The Dragonfly erosion specialists offered alternative measures of erosion repair and erosion control to restore and improve the appearance of the spillways.
The placement of the PVC pipe caused the secondary spillway to fail and badly erode. Heavy water flow caused the spillway below the pipe to wash away.
As part of our erosion repair, we implemented erosion control measures. We extended the PVC pipe to the toe of the spillway.
The crew covered the pipe with fabric and placed riprap over the fabric. Riprap is loose rock or stone. Securing fabric and riprap over the pipe will armor the spillway to prevent future washout.
Dragonfly’s erosion repair restored this secondary spillway and our erosion control measures will help prevent future washout.
Erosion Repair of Primary Spillway
The primary spillway had eroded badly due to the previous improper repairs.
First, the crew removed all of the fabric and riprap from the spillway.
Next, the Dragonfly team regraded the spillway to the proper swale. Soil that had been washed downstream was replaced by fill dirt. A swale is a channel designed to manage water runoff and filter pollutants.
Several erosion control measures were also incorporated into the erosion repair of the primary spillway. Rows of boulders were placed on the spillway and T-posts were placed partway up the spillway for added reinforcement. Riprap was placed around the boulders.
Next, concrete was drizzled on the area where the highest rate of water flow occurs. Lastly, we finished armoring the spillway by placing riprap over the remaining fabric.
The restoration of the primary spillway is complete. The Dragonfly Team implemented erosion control measures that will protect the spillway from future erosion.
Our Raleigh erosion repair project has successful restored both spillways. As a result, the spillway is once again able to effectively regulate water levels and overflow. The Dragonfly solution repaired all eroded areas, implemented erosion control measures, and improved the appearance. It is always our priority to complete projects properly and add aesthetic value.
