    An ongoing concern that geotechnical engineers must deal with continually is the indeterminable amount of disturbance that thin-walled tube samples are subjected to during sampling, handling, and transporting. The effects of the extrusion process should be of equal or greater concern. The monitoring and limiting of forces (loads) to which the sample is subjected during extrusion provides for some control of the degree of disturbance. This control is most critical for soft, loose, unsaturated, and sensitive soils. A simple method for calibrating an extruder is given.
