Don’t Wait for the Ground to Give Way!
Sinkholes and underground karst voids present major risks to infrastructure—from collapsing roadways to compromised building foundations. Waiting for surface subsidence is waiting too long.

Why rely on single-method guessing games or costly exploratory drilling when you can get a complete subsurface picture? At Bigman Geophysical, we use a powerful multi-sensor approach to catch hidden voids before they breach the surface:
Geonics EM38B Electromagnetic Induction: Rapidly scans broad areas for soil conductivity changes, tracking moisture pooling and soil variations to create a site-wide anomaly map.

Ground Penetrating Radar (GPR): Delivers targeted, high-resolution 3D imaging to map the exact dimensions of voids, soil raveling, and structural risks.
Together, this multi-sensor synergy saves time, eliminates blind drilling guesswork, and protects critical infrastructure.

No single NDT technology can do it all.

When evaluating concrete structures, relying solely on Ground Penetrating Radar (GPR) leaves critical blind spots. Dense rebar mats can cause signal shadowing, and paper-thin air delaminations often pass right through electromagnetic waves unnoticed.
By combining GPR with Ultrasonic Pulse Echo (UPE), we bridge the gap between electromagnetic mapping and acoustic precision:

Speed & Mapping (GPR): Rapidly scans large surface areas to deliver precise 3D layouts of rebar, conduits, and slab thickness.
Integrity & Flaw Detection (UPE): Uses acoustic impedance to pinpoint subtle air gaps, honeycombing, internal cracking, and delaminations.

Eliminate the guess work before coring, saw-cutting, or retrofitting.
Eliminate diagnostic blind spots with a complete, multi-physics approach.

Severing a post-tension (PT) cable isn't just an expensive construction mishap—it's a critical structural hazard and severe life-safety risk.
PT cables sit under tens of thousands of pounds of force. Striking one during routine core drilling, saw-cutting, or anchoring can cause the tendon to burst violently through the concrete slab, leading to severe injuries, sudden structural load failure, and immediate site shutdowns.
Because PT cables drape up and down throughout a slab rather than staying in flat grids like rebar, specialized Ground Penetrating Radar (GPR) scanning is essential before any blade touches the surface:

Isolates PT Cables from Rebar: Tracks continuous 3D scan profiles to identify the signature parabolic "drape" of PT tendons.

Maps Depth & Clearance: Pinpoints concrete cover with millimeter precision to establish safe zones for drilling and anchoring.

Provides Real-Time Site Marking: Maps cable trajectories directly onto the slab surface, giving cutting crews a clear roadmap.

Don't leave structural integrity to chance. Replace guesswork with safety and certainty before your next coring or renovation project.
