Spillway Management

Stabilize spillways and overflow channels with GEOWEB® geocells.

Spillways, overflow channels, and emergency flow paths are exposed to concentrated runoff that can cause erosion, washouts, scour, and long-term damage. The GEOWEB Soil Stabilization System helps protect these critical areas by confining infill within a 3D cellular structure to improve surface stability and resist movement during flow events.

The GEOWEB system can be designed with vegetation, aggregate, or concrete infill depending on hydraulic conditions, slope geometry, and performance requirements. Vegetated infill can provide a more natural appearance for lower-flow applications, while aggregate or concrete infill can support more demanding spillway and overflow conditions.

For dams, levees, stormwater facilities, and flood control infrastructure, the GEOWEB geocells provide a flexible solution for spillway erosion control, overflow protection, and long-term channel performance.
