Every method below is run by our own crews on our own instruments. Combining two or three is often what turns an ambiguous anomaly into an answer, so most pages say plainly which other method belongs alongside — and where a method will not work on your ground, we would rather tell you before you commission it.
Ground-penetrating radar
The highest-resolution picture available of the first few feet of ground, and the only geophysical method that images inside a concrete slab. Radar is where most of our work starts.
ApplicationsConcrete scanning and imaging
Before anybody cores, cuts or drills. Rebar, post-tension tendons, conduit and slab thickness located and marked on the surface, with the crew standing there waiting.
ApplicationsUtility locating and subsurface utility engineering
One-call marks the utilities their members own. Everything else on the site — the private network, the abandoned lines, the ones nobody has a record of — is the part that stops a job.
02 / ElectromagneticElectromagnetic surveys & TDEM
Where radar stops, electromagnetics usually starts. Conductive ground defeats radar and is exactly what EM measures well — which is why the two methods so often run together.
03 / ElectricalElectrical resistivity site assessments
The method that sections the ground. Where a project needs to know what the geology actually does with depth — not what a boring 200 ft away suggested — resistivity imaging is usually the answer.
04 / SeismicSeismic surveys — refraction and reflection
Elastic waves measure how stiff the ground is, not just where the layers are — which is why seismic answers engineering questions the other methods cannot touch.
Seismic / CodeSeismic site classification — MASW and ReMi
ASCE 7-22 assigns site class by shear-wave velocity alone. If your geotechnical report derived a class from blow counts, it no longer rests on an accepted basis.
05 / Potential fieldMagnetic surveys
A passive method that needs no source and no ground contact. If the target contains iron or steel, magnetics will usually find it faster and cheaper than anything else.
Renewables / MagneticsAbandoned oil and gas well location
Estimates put undocumented orphaned wells in the United States somewhere between 310,000 and 800,000. Solar and wind developments cover large acreage in precisely the country where they were drilled.
05 / Potential fieldMicrogravity surveys
Every other method looks for something. Gravity looks for the absence of something — which makes it the most direct way to prove a void exists, and one of the few that works where radar and resistivity are both defeated.
06 / Laser scanningLiDAR and 3D laser scanning
Millimeter capture of what is actually there, rather than what the record drawing says was built. A registered point cloud you can measure, section and hand straight to a designer.
07 / Thermal imagingInfrared thermography
Heat gives a defect away long before anything has to be opened up, lifted or cut. A service in its own right, inside buildings and out, with handheld cameras and a thermography drone.
08 / ThermalSoil thermal resistivity testing
How quickly the ground carries heat away decides how much current a buried cable can carry. Assume it, and the feeder is either undersized or paid for twice.
09 / BoreholeBorehole geophysical logging
Where a hole already exists, log it. A single logged borehole can convert an entire surface survey from an interpretation into a calibrated measurement.
DeliverablesGIS mapping and CAD deliverables
A finding nobody can locate again is not a finding. Everything we collect is positioned to survey grade and delivered in a form your designers can build on directly.
Ask before you commission
Tell us the target, the ground and the constraint and we will say whether this method answers it, whether it needs a second method alongside, or whether something else entirely is the better route. That conversation is free and it is usually short.
