Introduction
Soil erosion is a major environmental issue in Southeast Asia (SEA), especially in countries like Indonesia, Thailand, Vietnam, and the Philippines. Heavy rainfall, steep slopes, and deforestation contribute to land degradation. To combat this, engineers and environmentalists use geomembranes—a type of synthetic liner—to stabilize soil and prevent leaks in landfills, ponds, and mining sites.
This case study examines how geomembranes were successfully used in a land reclamation project in Vietnam to reduce soil loss and improve water retention.
Project Background
-Location: Coastal area in Southern Vietnam
– Problem: High tides and heavy rains caused soil erosion, affecting nearby farming land and fish ponds.
– Solution: Installation of a high-density polyethylene (HDPE) geomembrane to act as a barrier against water flow.
Implementation Process
- Site Preparation: The ground was levelled and cleared of rocks and debris.
- Laying the Geomembrane: The HDPE liner was rolled out and welded together to prevent leaks.
3.Anchoring: The edges were secured with soil and rocks to avoid movement.
- Testing: The team checked for tears or weak spots before final use.
Results & Benefits
After 6 months, the project showed:
Reduced soil erosion by 70%
Improved water storage for agriculture
Lower maintenance costs compared to traditional methods
Conclusion
Geomembranes are a cost-effective and durable solution for soil protection in SEA. This case study proves that proper installation can prevent land damage and support sustainable development。
