The construction of the new Istana Negara (National Palace) at Jalan Duta required extensive slope stabilization and strengthening works. The site presented significant challenges due to its location at the geological interface of Granite, KL Limestone, and Kenny Hill formations, which posed serious stability risks to the unprotected engineered slope.

To address these issues, Steel Grid SGMO with MacMat and hydroseeding were implemented to improve slope stability and control erosion. This environmentally friendly solution aligns with the project’s ‘green development’ concept, creating a sustainable, carbon-sequestering structure that blends naturally into the surrounding environment.

Approximately 3,500m² of SGHR30 with MacMat was installed, reinforced with soil nails, to secure the 32-meter-high slope, ensuring long-term stability and safety for this landmark development.

This comprehensive approach not only mitigated the geotechnical challenges but also exemplified the integration of sustainable engineering practices in modern infrastructure projects, setting a benchmark for future developments.
