Geotechnical Sensors

Geotechnical sensors measure subsurface pore pressures, soil and rock deformation, surface settlement and heave, stress, strain and load in ground and structures, as well as movement and forces in retaining systems.

They deliver accurate, real-time data that helps construction teams anticipate and manage risks, make informed decisions, and safeguard critical infrastructure from damage or failure.

Aiming for total safety

Earthworks, excavations, foundations and subsurface activities must be monitored to detect changes in ground conditions and manage safety risks.

Geotechnical sensors provide early warning of unusual behavior that could escalate into major risks during construction or throughout an asset’s life. They support the optimization and verification of underground designs and enable long-term condition monitoring.

These sensors are essential for assessing soil behavior such as landslips and settlement, diagnosing root causes, evaluating deconsolidation risks, and determining when reinforcement or remediation is required.

Geotechnical sensor types

Geotechnical sensors provide reliable insight into soil and rock behavior during and after construction. They detect movement, pore pressure changes and stress variations early, supporting safer excavation, stable foundations and well-informed design decisions.

Our solutions include a comprehensive range of proven instruments:

Ground movement sensors – inclinometers (manual and automatic), extensometers, shape arrays and settlement systems for tracking lateral and vertical displacement within soil and rock.
Pore pressure sensors – vibrating-wire, hydraulic and standpipe piezometers, plus a variety of dataloggers, to understand changing behavior.
Strain and load sensors – load cells, earth-pressure cells and strain gauges to quantify forces acting on support systems, tunnel linings and retaining structures.
Tilt sensors – high-precision tiltmeters for detecting rotational movement in shallow ground or buried structures.
Thermistors – integrated temperature measurements ensuring accurate, compensated readings under variable ground conditions.

Through continuous subsurface monitoring, geotechnical sensors enable better decisions, enhanced safety and long-term asset resilience.

The benefits of geotechnical sensors

Using geotechnical sensor data enables you to:

Manage geotechnical risks associated with excavation, foundation works and subsurface structures.
Understand actual soil behavior, providing a sound basis for:
- Verifying actual ground deformation against design assumptions.
- Optimizing the design and performance of foundation and retention systems.
- Anticipating and mitigating hazards such as landslips or ground slump.
Monitor ground conditions over the long term, including the stability of embankments, cuttings and other earth structures.

These insights support safer construction, more reliable asset management and better-informed decision-making throughout the project lifecycle.
