RockFlex Rock Bags

Engineered Rock-Filled Bags for Scour Protection & Erosion Control

RockFlex is MMC’s heavy-duty rock-filled net bag system designed for scour protection, erosion control, revetment construction and marine infrastructure stabilisation.

RockFlex units are manufactured from high-strength, UV-resistant synthetic netting and filled with locally sourced graded rock to create flexible, high-mass protection units that can be rapidly installed above or below water.

Unlike conventional loose rock armour, RockFlex contains the rock within an engineered net system, allowing individual units to be lifted, positioned and installed accurately.

Applications

RockFlex is suitable for:

  • Coastal erosion protection
  • Seawalls and revetments
  • Bridge pier and abutment scour protection
  • Culvert and stormwater outlet protection
  • Riverbank stabilisation
  • Pipeline and cable protection
  • Marine structure scour protection
  • Emergency erosion remediation
  • Shoreline protection
  • Underwater scour and seabed stabilisation

Flexible, Rapid Installation

RockFlex units conform to irregular ground and seabed profiles, making them suitable for locations where conventional rock armour, gabions or concrete structures may be difficult or slow to install.

Units can be manufactured in a range of sizes and weights to suit project requirements, including heavy-duty bags for marine and underwater installation.

Local Filling & Project Supply

MMC can supply empty RockFlex units for local filling or provide a complete project package including:

  • Engineered RockFlex bags
  • Locally sourced graded rock
  • Filling frames and equipment
  • Lifting and handling systems
  • Proof-load testing where required
  • Installation methodology
  • Crane, excavator, diver or marine installation support
  • Scour protection and revetment design support

Using locally sourced rock can significantly reduce transport costs and allows RockFlex systems to be manufactured close to the project site.

Complete Scour Protection Solutions

RockFlex can be used independently or incorporated with MMC’s other scour and erosion-control systems, including:

MMC can assist with selecting the most appropriate protection system based on site conditions, hydraulic loading, design life and installation requirements.
