Groundwater measurement

There can be many reasons why it is necessary to know the groundwater levels. This can e.g. be if you know construction, where you want to know how far down to the groundwater. This is also called a groundwater level. The groundwater level is continuous and fluctuates, depending on what time of year it is.


Excavations and installations underground often hit a very real problem – the groundwater. It is a particular problem when excavating in water-bearing soil (such as sand and gravel) or fractured rock (such as chalk or sandstone). Without suitable control measures, groundwater inflow can flood excavations or tunnels and can also lead to instability when the soil or rock around the excavation weakens and collapses – either locally or on a large scale. Over the past few decades, there have been several high-profile projects around the world that have been seriously delayed by groundwater issues. On the other hand, a far greater number of projects have successfully managed groundwater without obvious problems.

The first thing to do to ensure that groundwater can be managed effectively is to gather information on site to understand the problem. This involves an investigation which involves drilling and testing, measuring groundwater levels, as well as testing the permeability of the soil. Permeability describes how easily water flows through soil or rock. Soils and rocks with high permeability tend to be water-bearing and are typical of the conditions where groundwater can cause problems for construction projects.


With our equipment, we can help to continuously monitor the groundwater levels, so that through monitoring, you ensure that accidental water does not flow in. The system can send out an alarm if the groundwater rises above the set level.
