Soil slope netting is a reliable solution for stabilizing and protecting slopes from landslides and erosion. This system integrates wire mesh, soil or rock nails, plates, steel ropes, and rope anchors to secure unstable slopes and reduce the risk of failure.

The project employed Steel Grid SGHR 30 and Steel Grid SGMO with MacMat, a geo-composite PoliMac system designed as a drapery solution. The “Double Twist” steel grid technology ensures durability and prevents unraveling. The steel wires and ropes conform to EN standards, ensuring high performance and reliability.

The design utilized Mac S – Design, a software tool by Officine Maccaferri, which adopts the Limit Equilibrium Method to meet both Ultimate Limit State (ULS) and Serviceability Limit State (SLS) criteria.

A 34-degree cut slope near a TNB 132kV pylon was experiencing instability due to Kenny Hill residual soil and a high groundwater table. Prolonged heavy rainfall during the monsoon season caused severe erosion and tension cracks at the slope crest, worsening stability.

To address these challenges, Steel Grid SGMO with MacMat combined with hydroseeding was used to improve slope stability and erosion control. This environmentally friendly solution also blended with the surrounding greenery for a natural appearance. Approximately 1,800m² of SGHR30 with MacMat was installed on the 25-meter-high slope, reinforced with soil nails to ensure long-term stability and durability.
