Overview
Ground Penetrating Radar Survey in Kenya
Ground Penetrating Radar (GPR) surveys use electromagnetic pulses to detect and map buried utilities, voids, rebar, and subsurface anomalies without excavation. GPR is the primary tool for pre-excavation utility mapping, concrete scanning, and void detection across construction sites in Nairobi and beyond.
SmartGrid Surveying uses GSSI-class GPR systems with experienced operators, delivering same-day preliminary findings and detailed reports with CAD-ready drawings.
Searching for a ground penetrating radar survey near you? Our GPR teams are based in Nairobi and dispatch across Kenya — Kiambu, Nakuru, Kisumu, Mombasa — with most requests mobilized within 24 hours.

Compliance
Subsurface Utility Engineering (SUE) Compliance
We apply international SUE standards to every utility mapping project — giving engineers the confidence to excavate safely:
SUE Level D
Records & Desk Studies
Compile existing as-builts and utility records to build an initial risk picture before fieldwork.
SUE Level C
Surface Utility Mapping
Locate and record visible surface features — manholes, valves, poles — and correlate them with records.
SUE Level B
GPR & Geophysical Detection
Deploy GPR and EM locators to detect, map and classify buried utilities without excavation.
SUE Level A
Physical Verification (Potholing)
Safely expose utilities to confirm exact depth, size and material before construction.
Ensures engineering-grade confidence before excavation
Transparency
Technical Limitations (Transparency You Can Trust)
Ground Penetrating Radar performance depends on site conditions. We tell you exactly what to expect:
Clay Soils
Heavy clay attenuates the radar signal and reduces effective penetration depth.
Dense Reinforcement
Concentrated rebar and mesh cause signal scattering and clutter inside concrete.
Wet Ground
High soil moisture changes the dielectric response and can mask target signatures.
Maximum Effective Depth
Typical detection depth varies between 0.5m – 4m depending on soil and antenna configuration.
We combine GPR with EM locating & site verification to improve reliability.

FAQs
Frequently Asked Questions
A GPR (Ground Penetrating Radar) survey uses electromagnetic pulses fired into the ground to locate buried utilities, rebar, voids, and other subsurface features without excavation or drilling. The radar unit is pushed across the surface and the reflected signals are processed into a map showing the depth and position of detected features.
Detection depth depends on soil type. In sandy or volcanic soils we typically achieve 3-8 meters of penetration, while wet clay heavily attenuates the signal and may limit depth to 1-2 meters. Where deeper targets are expected, we deploy lower-frequency antennas and combine GPR with electromagnetic locators.
Yes. Concrete scanning is one of the most common GPR applications — we locate rebar, post-tension cables, conduits, and voids within slabs, walls, and beams quickly and without any damage to the structure.
Preliminary findings and on-site markouts are provided immediately after scanning. Full interpreted reports and CAD drawings are delivered within the timeline agreed for your project — typically a few days depending on site size.
Completely safe. GPR emits low-power radio waves — there is no radiation risk to people, and the method is entirely non-destructive, making it ideal for occupied buildings, hospitals, and live industrial facilities.
Our GPR teams are based in Nairobi and mobilize countrywide — Kiambu, Nakuru, Kisumu, Mombasa, and beyond — with most requests scheduled within 24 hours.
