Foundation Investigation

For new and old infrastructural projects where neither as-built nor condition information is available, we provide several avenues to investigate image foundation structures including piles (and deep foundations) in earth and marine environments.


Such applications include:


  • Pile integrity testing (PIT) or“Low-strain dynamic pile test in accordance to ASTM D5882-16 and AS 2159-2009 methodology.


  • Depth and condition assessment of foundation (concrete, wooden, steel)


  • Structural life-span assessment (insurance and real estate)


  • Forensic investigations after natural disasters, hurricanes, earth quakes, flooding


  • Post-damage evaluation


  • Safe planning of horizontal drilling and subsurface infrastructure expansion projects


Parallel Seismic


Parallel Seismic (PS) is a borehole test method developed for the determination of unknown depth of foundation elements. It can also detect major anomalies within a foundation as well as provide the surrounding soil velocity profile information


The depth of the foundation is determined by plotting the first arrival times as a function of depth and observing the depth where a change of slope occurs.


Alternatively, the foundation depth can be determined by observing the depth where the signal amplitude of the first arrival energy is appreciably reduced.


Simplified Geophysical Interpretation 


Results are presented in a simplified format relevant to engineering purpose. Outputs may include:


  • Depth of foundation
  • Lithology and velocities of medium
  • Location of defect along the foundation,
  • Moduli properties (Bulk modulus, Shear modulus) for engineering design.
