For this project, we replaced an aging rip rap flume to enhance water flow management and erosion control. Work began with the careful removal and stockpiling of the existing large rip rap for reuse, as well as the disposal of deteriorated filter fabric.
We then re-excavated the subgrade to a precise V-shaped depth of 18 to 24 inches to ensure proper drainage, hauling off unsuitable material due to limited on-site fill options. A new geotextile fabric was installed, carefully pinned and trenched around the perimeter to guard against water infiltration beneath the structure.
Reconstruction included resetting the salvaged large rip rap at the base and topping it with a layer of smaller rip rap for a clean, consistent finish. The rip rap was shaped to match the surrounding terrain and promote optimal flow.
To complete the work, we stabilized all disturbed areas using seed, fertilizer, lime, and straw, supporting long-term erosion control and healthy vegetation regrowth. This project significantly improved the durability, appearance, and functionality of the flume system.
