Terra Monitoring | Excellence in Action

Geotechnical Instrumentation

We specialise in the supply and installation of sensors that monitor the heartbeat of sub-surface conditions.

• VIBRATING WIRE PIEZOMETERS (VWP’s): For quality monitoring of pore water pressure in dams and tailings storage facilities.
• INCLINOMETERS & EXTENSOMETERS: Providing precise measurements of lateral and vertical ground movement to detect early signs of instability.
• SHAPEARRAYS: An advancement of traditional inclinometers, ShapeArrays consist of a string of segments connected by flexible joints. These are installed into boreholes or attached to structures to provide automated, real-time 3D deformation data. ShapeArrays remain in the ground to provide continuous high-resolution spatial data without the need for manual probing.
• TILTMETERS & CRACK GAUGES: Critical for structural health monitoring in buildings, bridges and tunnels.

Wireless Data Acquisition Systems

In recent years, there has been a significant increase in the demand for near real-time monitoring, a service we are proud to offer. Equipment pieces are connected to remote data loggers that send through measurement readings remotely to a centralised control room and send through notifications to selected contacts directly. Thus, eliminating the need for manual reading to be taken.

• ALERTS: Instant notifications via SMS or email can be configured should movements exceed pre-determined safety thresholds.
• COMPATIBILITY: Our technicians are able to connect most measuring devices to the remote logging systems, allowing you a hands-on approach for mitigating risks.

Our collaboration with Geomech Africa and Geomechanics allows us to offer an integrated, turnkey service. For instance, on a single tailings project, the Group can provide sonic drilling, ideal for tailings soil conditions, S-CPTu testing, and various other in-situ services with the subsequent installation of world-leading monitoring instrumentation, all managed under one roof.
