Monitor Ground Movement

Reliable instrumentation for monitoring ground movement

Reliable geotechnical instrumentation and monitoring for construction, infrastructure and civil engineering projects. From continuous monitoring of embankments, structural settlement, load and stress testing, NVM provides the instrumentation, installation and technical expertise to give you confidence in what is happening on site.

Where monitoring matters

Embankments

Monitor settlement, pore pressure and deformation during construction and throughout the life of the embankment.

Slopes & Landslides

Track subsurface movement and groundwater conditions to identify changes in slope stability and emerging instability.

Typical instrumentation
Inclinometers · Piezometers · Settlement systems · Data loggers

Tunnels & Excavations

Monitor ground movement and settlement around excavations to help protect works, nearby structures and infrastructure.

Dams

Measure pore pressure, settlement and deformation to assess dam performance, stability and long-term behaviour.

Foundations

Monitor settlement and structural response to verify foundation performance during construction and under changing loads.

Ground Improvement

Measure settlement and pore pressure to verify consolidation and confirm that ground improvement is achieving its design objectives.

Typical instrumentation

Piezometers · Settlement systems · Inclinometers · Data loggers

Structural Movement

Monitor changes in movement, rotation and cracking to identify developing structural deformation over time.

Retaining Structures

Track wall movement, ground deformation and groundwater pressure to assess the performance of retaining structures during excavation and construction.

The right instrumentation for your site

No two sites behave in exactly the same way. The right monitoring system depends on the ground conditions, structures involved, construction activity and the type of movement or change that needs to be measured.

NVM can specify, supply and install individual instruments or combine multiple technologies into a complete monitoring system. By bringing measurements together, we can give project teams a clearer understanding of ground and structural behaviour and help identify changes before they become a problem.

Groundwater pressure

Piezometers systems

Monitor pore water pressure and understand changing ground conditions.

Our piezometer systems measure pore water pressure within soil and rock, providing valuable data to help assess slope stability, excavation conditions and the performance of earthworks and containment structures.

We provide a range of piezometer technologies, including standpipe, pneumatic and vibrating wire piezometers, selected to suit the ground conditions and monitoring requirements of your project.

Reliable pore pressure data helps design and construction teams establish safe rates of fill, excavation and dewatering, identify changes in ground conditions and manage geotechnical risk throughout a project.

Lateral ground movement

Inclinometer systems

Monitor ground and structural movement with confidence.

Our inclinometer monitoring systems provide accurate data on ground movement, lateral displacement and pile deflection, helping you understand how your site and structures are performing throughout construction.

By monitoring slopes, piles, retaining structures and holding anchors, we can identify changes in movement and determine whether conditions are stable, accelerating or responding to remedial measures.

This gives your design and construction teams the information they need to identify potential issues early, manage geotechnical risk and take preventative action—helping keep your project within agreed safety, performance and design limits.

Structural Movement

Tiltmeters

Monitor structural movement and changes in inclination.

Tiltmeters measure changes in the inclination of structures and provide an early indication of movement or deformation. They are particularly useful where excavation, tunnelling, dewatering, loading or ground movement could affect the stability or performance of an existing structure.

Tilt monitoring can be used on retaining walls, bridges, buildings, dams and other structures to identify changes over time, assess the effectiveness of stabilisation measures and provide early warning of developing movement.

Reliable tilt data gives project teams the information they need to understand structural behaviour, respond to changes and take corrective action when required.

Crack Monitoring

Crack meters

Track changes in cracks, joints and structural movement.

Crackmeters provide precise measurements of changes in the width and movement of cracks in buildings, bridges, retaining structures, tunnels and other assets.

They can be used to establish baseline conditions and monitor whether cracks are stable, opening, closing or responding to construction activity or remedial works. This is particularly valuable where excavation, tunnelling, ground movement or structural loading could affect existing structures.

Continuous or periodic crack monitoring provides clear evidence of changes over time, helping engineers assess structural behaviour, identify developing issues and determine whether further investigation or intervention is required.

Vertical displacement

Settlement Systems

Measure settlement, consolidation and ground movement over time.

Settlement systems provide accurate measurements of vertical movement in soil, embankments, foundations and other structures. They can be used to monitor settlement and heave during construction, consolidation following loading or preloading, and changes associated with dewatering or tunnelling.

By tracking settlement throughout a project, engineers can compare actual ground behaviour with expected performance, identify developing movement and make informed decisions about construction and remediation.

Settlement monitoring can be applied to embankments, foundations, fills, storage tanks and other areas where changes in ground level need to be measured reliably.

Stress & Load Monitoring.

Pressure Cells

Measure load and stress within soil and structural materials.

Pressure cells are used to measure changes in stress and load within soil, rock and structural elements. They provide valuable information on how loads are distributed and how ground or structures respond during construction and throughout their service life.

Pressure cells can be used in embankments, dams, foundations and other geotechnical applications where understanding changes in internal stress is important to assessing performance and stability.

Reliable pressure measurements allow engineers to compare actual conditions with design expectations, monitor changes as construction progresses and identify potential issues at an early stage.

Displacement

Extensometers

Measure displacement and deformation between defined points.

Extensometers provide accurate measurements of movement or deformation within ground and structures. They can be used to monitor changes across excavations, tunnels, slopes, foundations and other areas where displacement needs to be measured over time.

By detecting small changes in distance between monitoring points, extensometers can help identify ground movement, deformation or convergence and provide valuable information on how conditions are developing.

Extensometer monitoring can be used alongside other geotechnical instrumentation to build a more complete understanding of ground and structural behaviour and support informed engineering decisions.

Automated data collection

Data Loggers / Telemetry

Automate data collection and keep track of changing site conditions. Our data logging systems automatically collect and store measurements from geotechnical instrumentation and sensors, providing a continuous record of ground and structural conditions throughout the monitoring period. Data loggers can be configured to record measurements at defined intervals, allowing monitoring systems to operate 24 hours a day with minimal manual intervention. This provides a more complete picture of changes over time and can help identify trends or developing issues that may not be captured through periodic manual readings. Collected data can be downloaded, reviewed and analysed using dedicated software, giving engineers and project teams access to reliable monitoring information to support informed decision-making and geotechnical risk management.
