The site presented a steep, erosion-prone slope requiring immediate and long-term stabilisation measures. The exposed soil was highly susceptible to erosion, particularly during rainfall events, creating a risk of soil loss and slope degradation before vegetation could establish.

A suitable solution needed to provide rapid installation, immediate surface protection, and reliable soil retention. It also had to integrate effectively with hydroseeding and revegetation works while ensuring long-term slope stability and minimal maintenance requirements.

Several erosion control options were evaluated with a focus on constructability, durability, and compatibility with revegetation methods. The key objective was to achieve immediate erosion protection while supporting long-term vegetation establishment and slope performance.

MacMat® R was used as a solution due to its reinforced geomat structure, consisting of a polymeric three-dimensional matrix extruded onto a double-twisted steel wire mesh manufactured from Galmac® (Zn/Al alloy) and Polimac-coated wire. This configuration provides effective erosion control and soil reinforcement while supporting vegetation establishment. Its three-dimensional matrix stabilises the soil surface and allows vegetation roots to develop through and interlock with the structure, promoting long-term integration with the natural environment and progressively strengthening slope stability over time.



The system was installed downslope, securely anchored, and overlapped to ensure continuous coverage across the slope. Its flexible design allowed it to conform closely to the ground profile, ensuring strong soil contact and providing a stable base for hydroseeding applications.

The installation provided immediate erosion protection, reducing the risk of soil loss during rainfall events and stabilising the slope surface from the outset. It also created a reliable base for hydroseeding, supporting effective vegetation establishment across the slope.

As vegetation develops, the system works in synergy with natural growth to further strengthen soil retention and improve overall slope stability. The result is a resilient, vegetated slope with enhanced long-term erosion control performance and reduced maintenance requirements.
