PRIMARY USE: Erosion control. ADDITIONAL USES: To reduce sediment in receiving waters. GABION REVETMENT
What is it? A revetment is a facing placed on a bank or bluff of stone to protect a slope, embankment, or shore structure against erosion by wave action or currents.
Purpose To prevent the erosion of banks.

Maintenance may be required to refill baskets whose stones have settled or been lost. Ga- Limitations bions should not be used at all where damage from water-carried debris is likely or where foot traffic over the revetment is expected.
Materials Stones, wire baskets.
The baskets must be solidly filled, or the wires will be abraded by movement of loose stones. Installation The stones must be large enough, usually at least four inches in diameter, to prevent loss of stone through the gabion mesh.
