The Labang–Tabau Bakun Road Water Supply Project presented significant geotechnical challenges from the outset. Located on low-lying terrain, the site was prone to frequent water ponding and characterized by a high groundwater table. Beneath the surface, soft and compressible soils with low bearing capacity posed a serious risk of settlement and instability.

These conditions made the construction of a stable filled platform particularly demanding. Ensuring the performance of the Terramesh retaining wall system required careful attention to stability, reinforcement anchorage, and effective compaction—especially under persistently wet ground conditions.

To overcome these constraints, a comprehensive ground improvement strategy was implemented. A granular working platform combined with basal geosynthetic reinforcement provided a stable and reliable foundation. At the same time, robust drainage solutions—including temporary dewatering and integrated internal drainage within the Terramesh system—were introduced to manage water levels and reduce pore pressure.

Construction was carefully staged to control settlement and minimize risk, while the use of free-draining backfill enhanced overall performance. The flexibility of the Terramesh system allowed it to adapt to ground movement, ensuring long-term stability and durability of the platform.

This project demonstrates how thoughtful engineering and adaptive design can transform challenging ground conditions into a solid foundation for infrastructure success.
