What this service does
Ground Penetrating Radar surveys use electromagnetic energy to identify changes below the surface without excavation. The technique is especially useful when buried services may be non-metallic, records are incomplete, or project teams need a continuous view of subsurface conditions rather than point confirmation alone.
Common applications
- Utility detection before excavation
- Void and anomaly investigation
- Pre-borehole and piling clearance
- Road and pavement investigation
- As-built verification support
Methodology
We start by reviewing drawings, target depth, planned intrusive works and access constraints. Field collection is then completed using a survey pattern appropriate to the site, with complementary locating methods used where they improve confidence. Findings are interpreted, positioned and issued in clear engineering deliverables.
Limitations and quality control
GPR performance depends on antenna frequency, target size, soil conductivity, moisture, salinity and site access. Dry sandy ground can be favorable; conductive clay or saline ground may reduce penetration. We therefore plan surveys around actual field performance and combine methods where appropriate.
Typical deliverables
- Marked-up plans and/or CAD drawings
- Depth annotations where technically supportable
- Survey coverage and methodology record
- Engineering report with findings and limitations
- GIS-compatible outputs when required
