Ground Penetrating Radar (GPR) Survey Prices: Understanding GPR Technology for Borehole Surveys
Ground Penetrating Radar (GPR) has transformed subsurface imaging in South Africa. This non-invasive method provides crucial insights for borehole surveys. It’s now a top choice for many industries.
What is Ground Penetrating Radar Technology
GPR creates detailed underground images using high-frequency electromagnetic waves. It’s a powerful non-destructive testing tool that collects data in real-time. The technology detects both metallic and non-metallic objects, making it highly versatile.
How GPR Works in Borehole Applications
In borehole surveys, GPR antennas are lowered into drilled holes. They send and receive signals that bounce off subsurface features. This process creates a detailed map of the underground environment.
The choice of antenna frequency affects depth penetration and resolution. Lower frequencies reach deeper but provide lower resolutions.
Benefits of GPR for Subsurface Investigation
GPR offers high-precision imaging, enabling accurate and cost-effective utility location. Its non-invasive nature makes it ideal for sensitive areas. Traditional methods might be too disruptive in such locations.
- Real-time results for quick decision-making
- High accuracy in locating buried objects
- Cost-effective compared to traditional methods
- Environmentally friendly approach
GPR mapping fees and ground radar detection costs vary. However, the technology often proves cost-effective in the long run. It allows for targeted ground investigations, potentially saving significant time and money.

Depth Capabilities and Coverage Areas – Ground Penetrating Radar (GPR) Survey Prices
GPR survey depth varies across South Africa’s diverse soil conditions. We’ll explore maximum depth penetration, survey coverage areas, and factors affecting GPR performance.
Maximum Depth Penetration in Different Soil Types
Soil composition greatly influences GPR depth penetration. In dry sandy soils, our equipment can reach depths of 30 metres.
This allows for thorough subsurface analysis. However, clay-rich or conductive soils may limit penetration to a few metres.
Survey Coverage Area Specifications
GPR coverage area typically spans 100 to 10,000 square metres daily. This range depends on required resolution and site accessibility.
For detailed surveys of underground tanks and utilities, we use 1-metre line spacing. This ensures accurate and cost-effective results.
Limitations and Environmental Factors – Ground Penetrating Radar (GPR) Survey Prices
Environmental factors impact GPR depth and survey effectiveness. Soil moisture, metallic objects, and vegetation can affect GPR performance.
GPR frequency is crucial. Lower frequencies offer better penetration but lower resolution. Higher frequencies provide improved resolution at the cost of depth.
In clean, dry, sandy soil, our low-frequency antennas can detect targets 30 metres deep. This showcases our equipment’s impressive depth penetration capabilities.
