Bridge Structural Health Monitoring Systems

With more than 60 years of experience, Soil Instruments is a recognized UK market leader in bridge monitoring. We deliver integrated monitoring solutions that combine robust sensors, intelligent datalogging, and remote connectivity to provide continuous, actionable insights into bridge safety and performance.

By transforming complex structural and geotechnical data into clear intelligence, we help engineers manage risk, optimize maintenance, and extend asset life with confidence.

Dataloggers and Remote Platforms (VWLOG2, GPRS, Sensly Monitoring Platform)

Read, record, and display data from multiple bridge sensors into a unified monitoring system.

Enable remote cellular transmission allowing asset managers to access near real-time information without frequent site visits.

Inclinometers (Digital Inclinometer, GEOSmart, Smart In-place Inclinometer, Inclinometer Casing)

Monitor horizontal subsurface deformation and potential slip-plane movement in embankments, slopes, and abutments supporting bridges.

Provide early warning of instability that could compromise foundations or approach structures.

Joint and Crack Monitoring (VW Crackmeter, VW Triaxial Jointmeter, Mechanical Jointmeter)

Track opening and closing of expansion joints and cracks in bridge decks, piers, and abutments.

Help distinguish normal thermal or traffic-induced movement from emerging structural distress.

Load and Pressure Cells (VW Load Cell, Strain Gauge Load Cell)

Measure loads in tendons and ground anchors to confirm that post-tensioning and anchorage systems perform as designed.

Support long-term assessment of load redistribution, corrosion effects, and rehabilitation measures.

Tilt sensors (Mems Tiltsensor)

Monitor rotation of key structural components such as decks, piers, towers, and bearings.

Identify changes in stiffness or support conditions that might indicate settlement or damage.

Piezometers and Water Level Meters (VW Piezometer, Standpipe Piezometer, Water Level Meter)

Measure pore water pressures in soils surrounding bridge foundations and approach embankments.

Support management of scour, seepage, and soft ground conditions that influence long-term stability.

Fiber Optic Sensors (SOFO deformation Sensors, Distributed Strain Sensors)

Accurately measure the long-term deformations of concrete elements to identify material degradation and quantify long-term rheological effects.

Detect and localize cracks in steel and concrete load-bearing elements.
