Borehole Rod Extensometer
Precise Monitoring for Ground Displacements
The Borehole Rod Extensometer EST-002 is a geotechnical instrument designed for monitoring relative displacement between points deep underground and a reference point at the surface. Ideal for a wide range of applications including settlement monitoring, deep excavation, and deformation of walls or rock masses, this tool offers high accuracy for long-term monitoring.
Key Features:
- Material: Fiberglass or stainless steel rods
- Number of rods: 1 to 6
- Range: From 50mm to 2000mm
- Accuracy: Exceptional precision with minimal thermal expansion due to fiberglass construction
- Protection Rating: IP67 (dust and waterproof)
- Installation: Easy to install with anchoring system; suitable for both manual and automated readings
Applications:
- Monitoring ground settlement in foundations
- Monitoring deep excavation projects
- Detecting and analyzing deformation in bulkheads and retaining walls
- Tracking rock mass displacement
- Monitoring tunnel and dam behavior
Ideal for projects requiring high-precision geotechnical monitoring, the EST-002 ensures optimal performance even in the most demanding conditions.

Turning ground movements into actionable insights
Geotechnical Monitoring

Geotechnical monitoring is essential for understanding how soil and rock masses behave under the stress of construction and natural forces. By providing continuous insights into ground movements and deformations, it helps engineers anticipate risks, protect infrastructure, and ensure the safety of people and assets. Advanced instruments designed for geotechnical applications make it possible to achieve reliable, long-term measurements even in the most challenging environments, turning complex data into actionable knowledge.
