Direct push HRSC tools—MIP, HPT, UVOST, TarGOST®—are powerful. But without site-wide context, investigations can still feel like assembling a puzzle with missing pieces.
That’s where GeoTrax Survey™ adds strategic value.
When used before direct push mobilization, GeoTrax Survey™ provides continuous lateral imaging across the site, identifying preferential flowpaths, LNAPL/DNAPL zones, and subsurface heterogeneity that discrete borings alone may miss. Instead of spacing borings on a grid and hoping to intersect impacts, teams can target borings based on real geophysical insight.
The result?
Fewer surprises. Smarter probe placement. More efficient drilling programs.
GeoTrax Survey™ is also independent of lithology. Where direct push encounters refusal, imaging can continue—providing continuity in areas where drilling cannot.
Importantly, GeoTrax Survey ™ and direct push HRSC are complementary:
Together, they correlate strongly and provide both detail and context. HRSC confirms permeability and contaminant presence; GeoTrax Survey™ defines extent and connectivity. The image below compares GeoTrax Survey™, TarGOST®, and conventional soil-boring: the GeoTrax Survey™ images were able to map the vertical/horizontal extents of DNAPL related impacts across the imaging domain where the impacted zones correlated with the more moderately electrically resistive anomalies (i.e., orange zones).
Conventional sampling and laboratory analyses still play a critical role, but when GeoTrax Survey™ guides the investigation, those samples are more targeted—and more defensible.
