- Place the rock bags along shorelines, beaches, seashores, and tidal areas for erosion control in coastal areas.
- Deploy them to protect the foundations of coastal and offshore structures such as piers, jetties, pylons, and piles for erosion management.
- Build rock groynes to reduce wave action, erosion, and control water flow
- Place on the sides of railway ballast and on subgrade embankments for erosion control in railways
- Use them in wharves and ship berths to prevent scouring of the revetment and reinforce toe protection.
- Pile them on a slope to prevent soil erosion
- Build headwalls around culverts and along road embankments using Rock Bags as erosion protection systems
What are the Other Applications of Bluemont Rock Bags™?
- Place them on submarine pipes and cables to protect the structures from corrosion and damage while preventing them from swaying or moving.
- Build cofferdams and floodways using Rock Bags to de-water specific areas or divert water in a different direction. It is useful during construction, heavy rain, or floods.
- Level uneven lakebed, riverbed, and seabed by piling Rock Bags
- Use them as an alternative for rock mattresses or as flexible gabions wherever necessary and suitable.
- Utilize them as an emergency erosion restoration solution in the case of sinkholes, road collapses, and floods.

Bluemont Rock Bags™ – Stronger, Last Longer
Standard Applications
| Application | Illustration | Note | Example |
|---|---|---|---|
| River Bank Protection |  | The bag is used at the front of bank independently as foot protection. The installation methods are step piling and random piling. |  |
| Foot Protection |  | Rock Bag is installed on the riverbed. In order to construct it without gaps, small size fillings are recommended. |  |
| River Dike Protection |  | Step pilling applies at a slope which becomes 1:2 or less(steep). |  |
 | Level installation applies at a slope which becomes more than 1:2 (loose). |  | |
| Riverbed Protection |  | Rock Bag is installed on the riverbed. In order to construct it without gap, small size fillings are recommended. |  |
Special Applications:
| Application | Illustration | Note | Example |
|---|---|---|---|
| Over Block |  | Rock Bag is used on foot protection blocks. It may be used as a vegetation base with earth covering. |  |
| Under Block |  | By using it under a foot protection block or a covering stone, an upside structure is stabilised from subsidence by sucking etc. |  |
| With Other Construction |  | Rock Bag installed in wooden pile or other methods of construction at inside, back and forth. The cooperation effect with other methods of construction is expected. |  |
| Protection Of Front Part |  | Bank protection etc. are stabilised by installing the Rock Bag in the front, such as gabion, sandbag and a sheet pile. |  |
| Emergency Procedure |  | Rock Bag is installed at a disaster place and erosion is prevented. An additional injection is possible because it has good flexibility. |  |
| Temporary Road |  | To avoid damage of Rock Bag by passing heavy construction machine directly on Rock Bag, please install steel plate on the top. |  |
| Filter Unit With Gabion |  | We recommend using Rock Bag and gabions together in places such as in water, where working with gabions alone is difficult. |  |
