Delivering engineering-grade buried services surveys and underground utility mapping across South Africa. We integrate multi-frequency Ground Penetrating Radar (GPR), electromagnetic locating, and Stonex GNSS / Total Station surveying to produce accurate CAD (.DWG), GIS, Google Earth (.KML), and PDF utility reports.

Select the exact subsurface investigation or pipeline service your project requires—from pre-excavation sweeps and slab coring clearance to CCTV camera diagnostics.
Subsurface & Concrete
High-resolution radar scanning to locate buried utilities, map rebar & post-tension tendons before core drilling, and detect subsurface anomalies.
All Buried Services
Complete underground scanning services combining GPR and electromagnetic locating to detect buried water pipes, electrical cables, and fibre in one visit.
Rebar & Post-Tension
Non-destructive slab and wall scanning to map rebar grids, post-tensioned tendons, embedded conduits, and cover depth before core drilling or cutting.
Metal, PVC & Concrete
Accurately locate and map buried water mains, sewer lines, gas pipes, and stormwater drains—whether metallic, PVC, HDPE, or fibre-cement.
Power & Fibre-Optic
Pinpoint live high- and low-voltage electrical power cables, street lighting feeders, and telecommunications or fibre ducts before digging.
Internal Camera Survey
Robotic crawler and push-rod camera inspections inside stormwater and sewer pipes to diagnose blockages, cracks, and root intrusion without digging.
You don’t just get a technician walking around with a scanner—you get immediate physical markings on the ground plus engineering-grade digital utility maps for your design and safety files.
Output 01 · Same Day
Every detected water pipe, power cable, telecom sleeve, or rebar grid is clearly marked on the ground or concrete slab with alignment arrows and estimated depth callouts so your crew can work safely right away.
Output 02 · Digital Map
Surveyed with our Stonex GNSS & Total Station instruments, all detected underground utilities are plotted onto high-resolution aerial imagery and CAD drawings for your engineers and architects.
Output 03 · Full Report
Comprehensive project documentation featuring annotated site photographs, radargram depth profiles, utility schedules, and methodology sign-off for your construction health & safety file.
Paint marks on the ground eventually wash away—engineering and construction teams need permanent digital records. As a dedicated GPR survey company, we capture the exact X-Y coordinates and burial depths of all detected underground services and overlay them onto aerial orthophotos and CAD drawings.
Comprehensive pre-design utility surveys for road upgrades, commercial developments, solar/wind farms, and industrial plants to eliminate utility clashes during the design phase.
All surface paint markings, manholes, valve chambers, and utility alignments are picked up with survey-grade GPS/Total Station and exported directly for your CAD draughtsmen.
Detailed written and photographic GPR reports including survey methodology, radargram depth profiles, utility attribute schedules, and confidence ratings.
Capture existing surface features, invert levels, manhole coordinates, and newly installed pipeline trenches before backfilling.
End-to-end subsurface detection, land survey pickup, and CAD drafting.
We review existing site drawings and establish GNSS / Total Station survey control across your project boundary.
Our utility surveyors locate and mark all buried water, sewer, stormwater, gas, electrical, and telecom lines.
Every marked utility alignment, depth point, and surface chamber is logged with centimetre-level GNSS or Total Station accuracy.
Our CAD & geomatics team processes the field data into layered AutoCAD (.DWG/.DXF), Google Earth (.KML), and PDF survey reports.

Our GPR survey report includes an executive summary, survey methodology, annotated site photographs of surface markings, interpreted radargram profiles, a schedule of detected utilities with estimated depths, and digital plan drawings in PDF, KML (Google Earth), and optional AutoCAD (.DWG/.DXF) formats.
Yes. If you provide your existing topographical survey or site layout in DWG/DXF format or coordinate system (e.g., Lo27 / Lo29 / WGS84), we georeference our utility detections directly onto your drawing layers.
Yes. Our survey teams mobilize nationwide for multi-hectare commercial precincts, mining corridors, municipal pipeline routes, and industrial facilities.
