Ground Penetrating Radar

Where GPR is Applicable:

• Reinforced and Unreinforced Concrete Slabs
• Bridge Decks and Pavements
• Floor Systems and Structural Walls
• Subgrade and Backfill Investigations
• Masonry, Rock, and Dry Ground Conditions

What GPR Can Detect or Characterize:

• Location and depth of rebar, PT cables, and conduits
• Slab thickness and multi-layer composition
• Detection of embedded utilities and metallic objects
• Identification of voids, honeycombing, or delaminations
• Mapping of corrosion-related anomalies or water ingress
• Internal characterization of floor, wall, or pavement systems

Key Benefits:

• Non-destructive and rapid deployment
• Real-time analysis in the field
• High-resolution imaging for near-surface investigations
• Reduces need for invasive exploratory demolition
• Enables better decision-making for rehabilitation or structural modification
