In-situ Testing
The Testing Process
Obtaining accurate geotechnical parameters of underlying soils is critical for the design of all temporary and permanent structures; in-situ testing reduces the effect of soil disturbance and allows testing in relatively undisturbed soils when open excavations can be avoided.
These test methods include:
Plate Bearing Tests
California Bearing Ratio (CBR) / Dynamic Cone Penetrometer (DCP)
We also offer several test options to provide strength profiles of underlying soils by means of:
Standard Penetration Tests (SPT)
Dynamic Probe Testing
Hand Shear Vane and Pocket Penetrometer
In-situ testing also allows the measurement of permeability, ground gas concentrations and groundwater levels which are measured within trial pits or borehole installations. These include:
Falling/rising head permeability test
Percolation Testing
Permeability/Soakaway Testing in accordance with BRE Digest 365
Borehole gas and groundwater monitoring
