Groundwater levels monitored in real time
Keep a reliable eye on groundwater level, pore water pressure and drawdown during construction works. With high-precision VW piezometers in boreholes, temperature-compensated and with automatic alerting on threshold exceedance.
Why groundwater monitoring
When the groundwater level decides on stability
Changes in groundwater level and pore water pressure act directly on excavation pits, tunnels, dams, transport routes and foundations. Professional monitoring detects these risks early and provides the data basis for safe and economical decisions.
Request a quoteGroundwater drawdown under control
During construction works with dewatering, the monitoring shows whether the drawdown stays within the planned range or endangers neighbouring buildings and the excavation pit.
Capture pore water pressure
VW piezometers measure groundwater level and borehole pressure permanently and with temperature compensation, decisive for the stability of excavation pits and dams.
Detect settlement early
Rising or falling water pressure signals settlement and heave long before damage to the structure or transport route becomes visible.
Real-time alerting
If a threshold is exceeded, the system alerts automatically so you can intervene before a critical situation develops.
Audit-proof documentation
Continuous data capture delivers an unbroken, traceable documentation for authorities and clients.
Radio instead of cable trenches
The measuring points transmit their readings by radio. This saves costly cabling across the site and makes even widely distributed boreholes practical.
Simulation
The level that reports itself
If the groundwater rises above the defined threshold, the system raises an alarm immediately. Play through the scenarios: a rising level after heavy rainfall, or a controlled drawdown during a construction project.
Normal level
The groundwater level is within the defined target range. All measuring points report green.

Measuring principle: VW piezometer
Vibrating-wire technology for maximum precision
At the heart of the system is a vibrating-wire piezometer. It measures groundwater level and pore water pressure via a vibrating wire, long-term stable, low-drift and insensitive to long cable runs. This keeps measurement quality intact over years and under extreme conditions.
- 01
Pressure action
Water pressure acts on a flexible membrane in the sensor.
- 02
Tension change
The membrane changes the tension of an integrated wire.
- 03
Frequency measurement
The wire’s vibration frequency changes in proportion to the pressure.
- 04
Data evaluation
The frequency is read out and converted into temperature-compensated pressure and level values.
Technical data
VW piezometer overview
Technical data for the PZ1050 model as an example. Filter: 50-micron sintered stainless steel, integrated temperature compensation.
We define installation depth, filter horizon and backfill for each measuring point.
To the concept serviceDistinction
Groundwater in the ground, level in the structure
This page covers the condition of the subsoil: groundwater level and pore water pressure, measured with VW piezometers in a borehole. Free-standing water is a different measuring task. Level and fill states in shafts, wells, standpipes and watercourses are captured by dedicated sensors, wireless and without a power and data line at the measuring point.
One point of contact
From the monitoring concept to ongoing monitoring
Infrasolute delivers the entire groundwater monitoring from a single source. From planning the measuring points through professional installation to operation, everything stays with one point of contact.
Concept
We plan measuring points, installation depths and filter horizons to match the subsoil and the requirements.
