Sediment movement on the banks of inland and coastal waterways can have a major effect on the embankments and shorelines. Wave action and streams erode the soil. But sediment movement also occurs on the beds of natural waterways and channels and needs to be eliminated long-term to ensure the banks remain stable. Using full-surface coverage heavy-duty geocomposites increases bed shear strength in waterways and the critical rate of flow above which erosion occurs.

Depending on the impact parameters in banks and beds, the Colbond product range of Enkamat erosion control mats offers two options to safeguard areas at risk:

For lower flow velocities, Enkamat product types with flat backs can be filled with gravel or stone chippings on site. For higher demands, the optimum level of erosion protection can be achieved by installing Enkamat A20, which comes pre-filled with a stone chipping/bitumen mix, stabilizing embankments immediately after installation.
