Insitu shear vane and piston sampling
Matrix Drilling can help you with your testing needs. We adapt a piston sampling method.
This method of testing is used for undisturbed sampling of soft to firm cohesive soils, sediments and fine-grained tailings.
Usually, it is used for sampling for laboratory strength and compressibility testing.
Features:
- Detailled field investigation of undrained shear strength and sensitivity of soft and medium stiff clays.
- From 0-30 metres by hand jack, even through hard layers of clay, sand and silt.
- Two vane sizes. Measurement range from 0 – 60kPa and 0 – 100kPa.
- Top level accuracy results, can be used for earth fill foundations and embankments.
Features:
- For undisturbed samples in very soft to stiff clays
- Stationary piston to avoid disturbances in overpressuredor very soft or loose soils
- Appropriate for sampling above and below ground waterlevel, at 0 to 30 m depth
- Combination use: Extension rods and tubes of the Geonorvane instrument H-10
- Can be used with most pushers, penetrometers
