Horizontal strain meter for monitoring lateral deformation in earth-fill dams and embankments.
The Geolook Vibrating Wire Soil Extensometer is designed to monitor lateral deformation and strain in earth-fill dams, embankments, and soil structures. Unlike borehole extensometers which measure vertical or angled movement in drilled holes, this instrument is installed horizontally in trenches during construction. It consists of two end flanges connected by a telescopic stainless steel rod protected by a PVC pipe. A vibrating wire displacement transducer measures the change in distance between the flanges, providing a precise measurement of soil extension or compression along the sensor's axis.

While settlement gauges measure vertical drop, the Soil Extensometer measures horizontal stretch or squeeze. This is critical in earth dams where internal cracking can occur if the core stretches too much due to differential settlement.
By installing these sensors in a chain across the dam core, engineers can detect potential tension cracks before they threaten the structure's integrity.
For a complete profile of ground movement, multiple units can be installed in series (end-to-end).
For example, a 50-meter long trench might contain ten 5-meter long extensometers. This creates a continuous monitoring line that reveals exactly which section of the embankment is stretching or compressing.
Buried sensors face immense crushing forces from the soil above. The G72-V560 features a unique telescopic outer housing.
This outer pipe moves freely with the soil, protecting the sensitive inner measuring rod from vertical soil weight and friction, ensuring that the sensor only records the true horizontal strain between the end flanges.
