Optimized for engineering structure assessment and urban infrastructure surveys.
Supports multi-frequency configurations for combined shallow/high-resolution and deeper/low-frequency scans.
Extended battery operation (8+ hours) for continuous fieldwork.
Rugged IP66 protection for outdoor and construction environments.
Modular software with options for pavement auto-tracking, bridge structure analysis, and 3D utility mapping.

Ground Penetrating Radar (GPR) is widely applied in geological hazard assessment, geotechnical engineering investigations and design, as well as in various civil infrastructure inspection projects. It is capable of detecting and identifying both metallic and non-metallic subsurface targets within a certain depth. The main applications include:

Geological Hazard Assessment:
GPR is used to detect subsurface anomalies such as voids, cavities, and fractured zones that may pose potential geological risks.

Geotechnical Engineering Investigation:
In engineering site investigations, GPR helps identify underground anomalies such as karst features, collapse zones, and fractured belts, providing critical data for design and risk control.

Municipal Utility Mapping:
GPR is utilized in urban construction to locate and map underground metallic and non-metallic pipelines, reducing the risk of accidental damage during excavation.

Road and Bridge Surveys:
It supports the detection of unfavorable geological conditions during the site selection and construction of roads and bridges, contributing to safer and more reliable designs.

Tunnel Inspection and Forecasting:
GPR is used for advanced geological prediction in tunneling and for inspecting the quality and integrity of tunnel structures during and after construction.
