Groundwater control describes the range of engineering techniques used to allow engineering excavations and mines to the constructed below groundwater level in workably dry, stable and safe conditions.
There are two main types of groundwater control techniques:
- Methods that use cut-off walls and other barriers to exclude water from the excavation (known as exclusion techniques).
- Methods that deal with groundwater by pumping (known as construction dewatering techniques).
There are a wide range of groundwater control methods and dewatering techniques available. The selection of the best method will depend on the geology and hydrogeology of the location, the available space and facilities and the environmental constraints at the site.
In the mining industry there are many applications where groundwater must be controlled for Mine Dewatering. Groundwater control is also used on construction and mining projects for Dewatering for Tunnels and Shafts. Where groundwater must be controlled to ensure long term stability or drainage of structures or facilities then Permanent Dewatering Systems are used.
