ROCK MECHANICS
GRM offers rock mechanics monitoring, geotechnical monitoring and rock stress measurements.
Ground geophysics
Geophysical measurements provide information in particular about the soil, the structures installed in the soil, the depth of the rock surface and the properties of the bedrock.
The services can be carried out in a wide range of conditions, including populated and unpopulated areas, tunnels, water systems, boreholes.
Please contact us and we will be happy to help you choose the most suitable methods!.
Rock mechanics
Monitoring
A single automatic measuring instrument such as an extensometer or any other device measuring pressure, stress, collapse, displacement, pouring or temperature.
Multiple sensors connected to a larger logging system
Automatic alarms
Real-time data
Manual measurements such as tunnel convergence measurement
Automatic convergence measurement with the so-called Basset system
Rock stress measurements
Hydraulic fracturing is a coarse 2D stress measurement method that allows two principal stresses to be measured. Measurements can be taken from the ground or from below ground. The current equipment can be used in 100 m deep holes, but the depth scale can be increased if the project so requires. Measurement works in 46mm - 60mm holes.
GRM offers monitoring of rock stress changes with adhesive HID cells.
