Measure the energy transferred by either an SPT hammer or a Becker Drill to increase the accuracy of energy measurement.

SPT Energy Calibration

SPT Energy Calibration consists of measuring the energy transferred by the Standard Penetration Test (SPT) hammer to the SPT rod.

Becker Drill

GRL Engineers implement the Becker Penetration Test (BPT) to measure the energy output of the diesel hammer used in the test, and to calculate the end bearing component of the driven Becker casing.
