What you receive
-
Maps of every layer and every finding
-
The report, and the survey itself in AMG Viewer Edition on your computer: every finding at its place on the map, to be queried years later, for tracking and monitoring. One year of licence included
-
Exports to Excel, CSV, DXF, GeoJSON, LandXML, Shapefile and KMZ for your GIS and CAD
What ground penetrating radar measures
-
Layer thicknesses along the whole section
-
Moisture, voids and delamination
-
Cracks, and in structures the reinforcement and the prestressing cables
Why trust the data
-
AMG Software, our own processing chain, built on twenty years of GPR research and on what our clients need
-
Strict methodologies and processes for on-site data collection
-
Years of experience with the equipment of the major GPR manufacturers and with other non-destructive methods
-
Each client and each project treated as unique: the equipment and the methods adapted to the client’s needs
Independent of the equipment manufacturer
-
The manufacturers sell instruments. AMG is the diagnostics expertise
-
Choose GSSI, Kontur or other manufacturers: the system that fits your needs
-
AMG Software processes the data whatever the manufacturer; AMG Viewer Edition delivers the diagnosis and unlocks automatic reporting, on your computer
Predict. Prevent. Preserve.
Maintenance by condition, not by calendar. In Finland alone, the state network’s repair backlog stood at 4.3 billion euros at the end of 2025, 2.6 billion of it on roads (Väylävirasto, 2026).
-
Predict: plans you can defend. Finland’s road agency already chooses its repaving from measured condition and backs its structural plans with bearing-capacity and ground-penetrating-radar surveys (Minister of Transport and Communications, 2025).
-
Prevent: lower lifecycle cost, fewer sudden closures. One dollar spent on preservation at the right time eliminates or delays six to ten dollars of rehabilitation or reconstruction later (Transportation Research Board, 2003).
-
Preserve: longer asset life, no coring, no closure. Each extra metre per kilometre of roughness raises car fuel use by 2 to 3 percent (Zaabar and Chatti, 2014).
