Ground Penetrating Radar & Concrete Scanning in SLO County

What Is Ground Penetrating Radar?

GPR sends radar pulses into concrete or soil and reads the reflections that bounce back from objects below the surface. The result is a real-time picture of what's inside a slab or under the ground — no digging, no drilling, no guesswork.

It's the right tool where electromagnetic locating can't reach: inside concrete, and for non-conductive targets like PVC pipe that carry no traceable signal.

Concrete Scanning Before You Cut or Core

Concrete scanning is GPR applied to slabs, decks, and walls. We scan before any cutting, coring, drilling, or anchoring so you know precisely what's embedded.

• Rebar and welded wire mesh
• Post-tension (PT) cables — critical to avoid before cutting
• Electrical conduit and embedded pipe
• Voids, honeycombing, and slab thickness
• Radiant heating lines and in-slab utilities

Subsurface GPR for Ground and Soil

GPR isn't just for concrete. In soil, it helps image targets that electromagnetic locating alone can miss — which makes it a strong complement to a standard utility locate on complex or undocumented sites.

• Non-metallic pipe such as PVC and HDPE
• Underground storage tanks and vaults
• Voids, disturbed soil, and buried debris
• Septic components and undocumented structures

When You Need GPR

Scan before core drilling, saw cutting, trenching through a slab, anchoring heavy equipment, or any structural modification. A few minutes of scanning prevents a struck post-tension cable, a flooded conduit, or a dangerous electrical strike — the kind of mistake that triggers emergency repairs and shuts a job down.

What You Get

Clear surface marks showing what's below, depth estimates where conditions allow, and a straight explanation of what we found so you can move forward with confidence. Call (805) 549-5752 to schedule a scan.
