- Seismographs for monitoring blasting and dynamic loading conditions.
- Impact echo and spectral analysis for integrity testing of piles and drilled shafts.
- Sonic logging for assessment of material quality in concrete caissons, diaphragm walls, mass   concrete foundations, dams and cut-off walls.
- Parallel seismic testing for evaluation of foundation type and depth beneath existing structures.
- Mechanical impedance testing for location of voids and assessment of support condition beneath   concrete floors, pavement slabs, airport runways and tunnel linings.
- Transient dynamic response for integrity and fixation evaluation in structures.
- Vibration analyzers and accelerometers to quantify the magnitude and frequency of the   background vibration levels within a facility.
- Impulse radar (GPR) to define rebar locations and subsurface anomalies such as foundations,   buried tanks and voids.
