Rock Revetment is a way of absorbing the energy coming from incoming waves and water. They are sloping structures comprised of various layers of large stone and geo-textiles placed on banks and shorelines used to prevent shoreline loss.
On the Great Lakes, rock revetments are the only form of erosion protection that we will install; it is the only long-term solution. Compared to seawalls, rock revetment provides a great, even better alternative to protecting beaches, homes, and other structures along the shorelines.
Typically, armor limestone rock is used to build rock revetment solutions.
Rock Revetment Advantages & Disadvantages
- Absorb wave energy
- Effective for generations
- Protects the Great Lakes’ sand-bars and beaches from long-term damage
- Assures natural beaches will re-form when water levels drop again
- Can be cost-effective compared to other techniques
- Costs can be higher due to expensive materials
- Installation is more challenging
