Ground Penetrating Radar
Subsurface imaging and detection services for construction, infrastructure and industrial applications in Houston and Dallas, Texas.
How it works
Ground Penetrating Radar (GPR) uses high-frequency electromagnetic pulses transmitted into the ground to detect subsurface features based on contrasts in material properties such as density, moisture, and dielectric composition. Reflected signals from interfaces—such as soil layers, groundwater, voids, rock, or embedded objects like rebar and utilities—are captured and displayed in real time as a 2D profile (radargram) as the antenna moves across the surface. Higher frequencies provide greater resolution but shallower penetration, typically up to 30 feet depending on soil conditions, with performance reduced in conductive materials like clay or saline groundwater. GPR is primarily used to map near-surface anomalies and structural elements, making it highly effective for applications such as concrete scanning, void detection, utility locating, and subsurface condition assessment, while allowing field technicians flexibility to adjust methods based on site-specific conditions.
Applications
-
Concrete Scanning
GPR concrete scanning locates post-tension cables, rebar, conduits and voids within concrete structures - giving your team the subsurface information needed before any drilling, coring or cutting begins. OmniVueNDT offers both real-time 2D scanning and advanced 3D grid-based imaging depending on project requirements.
-
Pavement Thickness Analysis
OmniVueNDT's RoadScan-GPR system evaluates pavement layer thickness and roadway conditions non-destructively at highway speeds. Results are delivered in GIS-integrated format to support asset management and infrastructure planning for DOT agencies and engineering firms.
-
Subsurface Void Mapping
Prior to crane placement or heavy equipment operations, OmniVueNDT performs GPR-based void mapping to identify hidden voids and loss-of-support conditions beneath industrial pads and pavement systems — reducing risk before high-load operations begin.
-
Utility Locating
OmniVueNDT uses GPR combined with electromagnetic detection technology to accurately locate and map buried utilities before excavation or construction begins - preventing costly strikes and keeping projects on schedule.
