Solutions for a complex world: Void Detection & Location Article by: Shawn Calendine | hydroGEOPHYSICS   The existence of voids in the subsurface can lead to significant ground surface failures and can pose a severe hazard for structures and people on the earth’s surface. Voids can…
  Solutions for a complex world: Pinpointing industrial pond liner leaks Article by: Shawn Calendine | hydroGEOPHYSICS   An unfortunate but simple truth about industrial geosynthetic liners (impermeable engineered geomembranes and HDPE sheets) is that most will eventually leak.  This…
Making Waves and Enhancing Site Investigations Dr. Nigel Crook uses a sledgehammer to hit a seismic source that generates controlled seismic energy used to perform both reflection and refraction seismic surveys.   Article by:   Jeremy Strohmeyer | Senior Project Manager |…
Joe Cain Pushing a Ground Penetrating Radar (GPR) cart at an urban site to locate subsurface pipes.   The greatest risks and unknowns at redevelopment sites are typically within the subsurface, this can pose significant challenges and require broad site assessments to be contracted by…
IP is a geophysical field technique used to quantify the chargeability of the subsurface.   Polarize your subsurface, not your client relations! Article by Moira Poje – hydroGEOPHYSICS Geoscientist As engineering and consulting professionals, we grapple with the challenges of designing…
By Moira Poje – hydroGEOPHYSICS Geoscientist   From site planning and geologic mapping to environmental/metallurgical characterization and monitoring, industries need flexible technologies to obtain information about the subsurface. Like a subsurface “camera,” electrical resistivity…
