Ground-Penetrating Radar & Subsurface Investigation
GPR scanning locates rebar, conduit, utilities, voids, and subsurface anomalies before drilling, cutting, or excavation. Findings are GPS-referenced and integrate with GIS, LiDAR, survey, and CAD data. GPR results depend on soil, material, depth, moisture, antenna frequency, access, and site conditions — we explain those limitations up front.

GPR findings depend on soil, material, depth, moisture, antenna frequency, access, and site conditions. Regulated work is performed by, reviewed by, stamped by, or subcontracted to appropriately licensed professionals when required by Hawaiʻi law.
Frequently Asked Questions
Can GPR find everything underground?
No technology can. GPR performance depends on soil conductivity, moisture, target depth and material, antenna frequency, and site access. We disclose the confidence and limitations of every scan.
