Flexible mesh bags filled with rock or riprap for scour and erosion control. A sustainable civil-engineering alternative to gabions, large rock, blockstone, riprap and rock mattresses, requiring no foundations and lasting 50+ years.
Evidence
When filled with rock or riprap, the Rock Bag is a flexible protection system, a sustainable environmental civil engineering alternative solution to gabions, large rock, blockstone, free riprap and rock mattresses.
A bag filled with small rocks works similarly to one large rock but more effectively. Bluemont Rock Bags™ placed on the site act as a barrier, preventing the water from washing away the soil or sand. The gaps between the small rocks also promote the growth of plant and marine life, strengthening the erosion control system further.
Bluemont Rock Bags™ come in different sizes, designed to hold 1, 2, 4, or 8 tonnes of rock. The filling frame for each bag will help you fill it accurately to meet the optimum volume and weight.

Protection of coastal and marine structures such as wharves, ship berths, shorelines, tidal areas, piers, jetties and subsea pipelines and cables from revetment and toe scour.
Evidence
Kyowa Filter Units, known as Bluemont Rock Bags™ protect wharves and ship berths from scouring of the revetment, toe protection.
The installation team filled and positioned Bluemont Rock Bags™ along the beachfront to establish a continuous protective barrier between the active surf zone and the campground.
Prevention of scour around bridge foundations such as pylons and piers, where hydraulic forces during flood events erode sediment and can gradually weaken the structure.
Evidence
Scour is one of the most serious threats to bridge foundations. The hydraulic forces generated during flood events can erode sediment from around bridge piles, gradually weakening the structural foundation.
Bluemont Rock Bags™ provided effective bridge scour protection around the bridge piles, stabilising the sediment bed and reducing the risk of erosion during intense weather conditions.
Control of water erosion in rivers, creeks, culverts and stormwater channels, stabilising banks, embankments and riverbeds while supporting vegetation growth.
Evidence
River bank erosion repaired and protected with Bluemont Rock Bags™
The installation team filled Bluemont Rock Bags™ with locally sourced rock and positioned them around the flume’s perimeter to establish a continuous protective barrier. The goal was to dissipate water flow energy and prevent further erosion of the supporting soil.
Protection of rail infrastructure from erosion and scour, including rail bridge pylon scour protection, embankment stabilisation, and emergency restoration of eroded ballast and subgrade.
Evidence
Emergency erosion restoration for flood water eroded ballast or subgrade.
Control of road erosion including culvert, embankment and slope protection, plus temporary crossings and work platforms for road construction and widening.
Evidence
Bluemont Rock Bags™ provide erosion management for a culvert outlet, and stability for loose riprap.
Protection of offshore and subsea structures, including submarine cables and pipelines, seabed levelling, artificial reefs, and scour protection for pylons and offshore foundations.
