A solution for groundwater control

Cut-off walls ensures the longevity of structures such as dikes or dams. It also allows for the confinement of working zones that might be polluted or to lower the ground water level.

Our processes

1. Mixing of cement bentonite slurry.

2. Excavation. Checking the verticality of trench after each 5m excavated.

3. Monitoring and add continuously cement bentonite slurry to ensure required level during excavation process.
