Deformation Monitoring

Reliable subsurface and surface movement monitoring for slopes,
embankments, structures and foundations.

Detect movement early – before it threatens stability.

Ground and structural movement often begins subtly: a millimetre of settlement, a shift in slope angle, a change in internal strain. Left unmonitored, these early indicators can develop into failures that impact safety, production and operational continuity.

Our solutions

Comprehensive Deformation
Monitoring Solutions.

We provide a full range of deformation monitoring systems designed to detect movement in slopes, embankments, foundations and structures. From deep borehole sensors to surface displacement tools, each solution is engineered for long-term accuracy and seamless integration into modern data platforms.

Deformation Monitoring

Deformation monitoring combines subsurface and surface measurement technologies to track how ground and structures move over time. Our solutions range from deep borehole instrumentation to wide-area displacement systems, all engineered for accuracy, longterm reliability and performance in harsh mining and civil environments.

We provide supply and installation of distributed fibre optic systems for continuous, high-resolution measurements.

Capabilities

Distributed Strain (DSS)

  • Detects strain along the entire cable length

  • Identifies shear zones, deformation, settlement, bending


Distributed Temperature (DTS)

  • Identifies seepage, leaks, thermal movement, groundwater behaviour


Distributed Acoustic Sensing (DAS)

  • Detects vibrations and acoustic energy

  • Useful for slope activity, cracking events, or pipeline disturbances


Your Offering

  • Installation up to the interrogator unit

  • All required software and data plugins

  • No in-house analysis, but full data delivery and integration



Applications

  • TSF embankments

  • Slopes and waste dumps

  • Pipelines and buried structures

  • Dams and foundations

  • Deep borehole deformation (strain profiling)


TDR systems are an effective early-warning tool for detecting deformation along buried cables or structures.

Applications

  • Slope movement

  • TSF embankment deformation

  • Buried pipelines (though fibre is often preferable)

  • Deep borehole installations (client provides drilling)


Capabilities

  • Coaxial cable installation where accessible

  • Telemetry integration

  • Configurable movement thresholds and alarm triggers

  • Clients use the TDR output for their modelling and interpretation

We install and commission high-precision GNSS sensors capable of long-term 3D displacement monitoring over wide areas.

Key Features

  • Millimetric 3D displacement accuracy for long-term structural and geotechnical monitoring

  • Extremely long battery life suitable for remote, unattended deployments

  • Low-power RTK corrections using long-range communication

  • Ideal for monitoring:

    • Pit walls

    • TSF crests

    • Large structures

    • Regional settlement/heave



GNSS systems complement borehole-based instrumentation by capturing large-scale surface movement where drilling is impractical.

We install full inclinometer casing for subsurface deformation monitoring and provide both manual measurements and automated solutions depending on the monitoring requirement.

Applications

  • Slope stability in open pits

  • TSF embankment monitoring

  • Retaining wall behaviour

  • Underground convergence and deformation

  • Excavations and foundations


Capabilities

  • Full casing installation in drilled boreholes

  • Training and commissioning for client-led manual readings

  • Automated IPI strings for continuous subsurface deformation

  • Long strings and complex borehole orientations

  • Underground and angled installations


Digital inclinometer chains (SAA-type systems) are included within our IPI offering for high-resolution continuous deformation profiles.

Extensometers are essential for monitoring internal ground displacement and structural deformation at depth.

We provide and install:

  • Multi-point borehole extensometers (MPBX)

  • Rod extensometers

  • Borehole anchor extensometers

  • Deep and angled installations

  • Surface readout or full telemetry integration


Use cases

  • Embankment stability

  • Underground deformation

  • Structural movement in foundations and abutments

  • Tracking settlement and heave through multiple horizons


We install settlement instruments for fill placement, embankment construction, and long-term TSF and foundation behaviour.

These systems provide:

  • Vertical displacement tracking

  • Consolidation performance

  • Fill settlement during staged construction

  • Telemetry integration for real-time observation


Both pneumatic and vibrating wire configurations are supported.

Tilt sensors provide highly sensitive movement detection for structural and geotechnical applications.

Applications

  • Buildings and retaining walls

  • Crushers, conveyors, and mechanical structures

  • TSF embankments and open pit infrastructure

  • Tanks, silos, stacks, and portals


Capabilities

  • Uniaxial or biaxial configurations

  • Long-term monitoring with alarm thresholds

  • Full telemetry integration

  • Event-based triggers for sudden movement

Integration With Groundwater Monitoring

Ground deformation and pore pressure behaviour are often closely linked. By integrating deformation sensors with groundwater instrumentation, we provide a more complete understanding of effective stress, shear strength and slope or embankment stability. This combined approach helps engineers diagnose causes of movement and manage risk with greater confidence.
Book a Consultation
Many forms of ground deformation are directly influenced by pore water pressure. Changes in pore pressure affect effective stress and shear strength, which in turn influence:
  • Slope stability
  • TSF embankment behaviour
  • Foundation performance
  • Consolidation and settlement
For this reason, deformation and groundwater monitoring are often deployed together to build a more complete understanding of behaviour and risk.

In other applications—such as structures founded directly on competent bedrock—the interaction between pore pressure and deformation is more site-dependent, and groundwater data may only play a supplementary role.

We base the monitoring design on site-specific conditions and engineering requirements.

Telemetry & Data Integration

All deformation instruments can be connected into a unified telemetry network, enabling continuous or scheduled data acquisition, long-range communication and real-time visualisation. Our data platforms support alarms, event detection and combined groundwater–deformation datasets, giving engineers clear, reliable insight into how ground and structural behaviour evolves over time.

All deformation instruments can be fully integrated into modern telemetry systems, enabling:
  • Continuous or periodic data acquisition
  • Low-power long-range communication
  • Real-time dashboards and visualisation
  • Alarm thresholds and event notifications
  • Unified platforms combining groundwater + deformation datasets
  • Underground and surface deployments
