Erosion Control on Railway Cuttings: EcoArmour® In Action

When a V/Line railway cutting in Merbein, Victoria fell into disrepair, Erizon® was called out to undertake a site visit and inspect the damage. During this visit, Erizon® noted substantial erosion that was visible at the batters, with the primary cause likely due to poor drainage that was supercharged by storm events, inappropriate cutting design, a lack of regular maintenance and potentially structurally weak soils. Thus, Erizon developed a tailored erosion control solution for the railway cuttings.

In addition to a standard site inspection, Erizon® also undertook a drone survey to generate a detailed 3D model to enable drainage modelling with a high level of accuracy and to determine the precise application area and rate for EcoArmour®.

 

EcoArmour® is a Hydraulically Applied Synthetic Erosion Control Blanket, Providing a Safer Alternative With a 20+ Year Longevity.

 

With an abundance of native plant species that had to be carefully managed, the objective from V/Line was clear:

  • Reduce adverse and ongoing degradation
  • Address complaints from all stakeholders
  • Implement a functioning asset for the future
After inspecting the site, the Erizon® staff noted the following project challenges:
  • The project would have a short duration due to high intensity, seasonal rainfall
  • They were working with a sensitive receiving environment (a tributary of the Murray River)
  • Working with poor and structurally weak soils
  • Necessary bridge abutment protection
  • Management of native plant species
  • Adhering to stringent project timelines
V/Line undertook independent, rigorous assessments for the available erosion control products on the market. Their requirements list included the following:
  • Product Warranty
  • Design Life
  • Installation Time
  • If there were any requirements for soil testing & amelioration
  • If the product could be applied on top of dispersive soils
  • If earthworks were required prior to the application of the product
  • If plantation was required
  • What the ongoing maintenance costs would be
  • If the product was able to offer resistance to hydraulic forces and the impact of raindrops
  • What the cost would be (supply & install)

At the conclusion of the independent assessments, the results were presented to V/Line by consulting engineers, and Erizon® was chosen as the preferred contractor to supply and apply our robust erosion control blanket (EcoArmour®) for different erosion zones within their site.

Why did they choose EcoArmour®?

EcoArmour®’s innovative synthetic erosion control blanket stabilises surfaces for 20+ years while providing a product warranty and guarantee. With no surface preparation works required prior to the application, EcoArmour® can be applied without testing and rectifying underlying soils and can be applied directly on top of dispersive soils.

With minimal ongoing maintenance costs, EcoArmour® can be applied quickly, utilising our specialist HydroRigs – and will dry within three hours of application. Compared to conventional alternatives like concrete matting and Shotcrete, EcoArmour® stands alone as a cost-effective solution that can withstand strong hydraulic forces.

From start to finish, Erizon® handled this project with a focus on utilising advanced technology to deliver our promise of “Supply, Apply, Guarantee®” and execute a plan specifically designed for erosion control on railway cuttings.

EcoArmour is an eco-friendly, sprayable synthetic erosion control blanket innovated by leading Australian environmental solutions provider Erizon. It has been scientifically developed to protect the soil surface from various degrees of erosion and withstand the harshest weather conditions– from dry, arid conditions to extreme wind and rain events.  Its unique blend
Mine Reclamation Mine reclamation is the process of restoring the environment for post-mining use once mining operations have ceased. This is done to mitigate the destructive effects caused by mining and to ensure the return of a sustainable ecosystem. Mine site reclamation involves four key stages: contouring the land, replacement of
Erosion Control
Erosion is a constant problem that needs consideration, no matter your site’s location. Erosion can, however be a much larger issue in many areas due to Australia’s climate. Much of Australia is made up of arid land, which is prone to the dangers of both wind, and water erosion. With
