A slurry wall is an engineered underground barrier constructed by excavating a narrow trench that is kept open using bentonite slurry, then filled with reinforced concrete to create a permanent, watertight structural element.
Construction Components
| Element | Specification | Purpose |
|---|---|---|
| Trench Width | 0.6-1.5m typical | Construction space |
| Depth Range | Up to 100m+ | Site requirement |
| Slurry Type | Bentonite clay mix | Trench stability |
| Reinforcement | Steel cage/panels | Structural strength |
| Final Material | Engineered concrete | Permanent barrier |
Construction Process
| Stage | Activity | Purpose |
