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:
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.
