HA Performance Trial

2004 saw the results of the TRL GPR Performance Trial 2003/2004 conveyed to the
participants and, as expected, Impulse Geophysics passed all required elements of
the trial.

Additionally Impulse Geophysics took part in the more techinally demanding 'optional'
test elements and were the only contractor able to measure the thickness of the
upper bituminous/PQ concrete road layer in the absence of core calibration
information to the standard required. Cores taken for calibration purposes are no
longer required. Cores are only needed to identify materials.
