NEAR SURFACE GEOPHYSICS & ASSET INTEGRITY
Near-surface geophysics is an efficient means of shallow subsurface investigation. FISAS geophysics and asset integrity service teams use the latest geophysical equipment and modern software to collect and provide high quality data on subsurface conditions for engineering design, and buried assets integrity for maintenance planning.
