Ground Penetrating Radar (GPR) – Non-Destructive Subsurface Scanning
At GEOCIVIL, our Ground Penetrating Radar (GPR) technology offers a reliable, non-destructive method for scanning a wide range of surfaces. Whether you’re detecting voids, reinforcing concrete, or locating utilities, our GPR units provide accurate and detailed subsurface data that helps reduce risk and cost across your projects.
GPR is a highly efficient tool for sensing both metallic and non-metallic features beneath the surface, making it invaluable for void detection, utility location, and structural assessment. This simple yet powerful technique ensures that unforeseen conditions are identified early, allowing you to manage projects safely and cost-effectively.
Our GPR Units
Noggin 1000MHz
Our Noggin 1000MHz is one of the most specialised GPR units available, specifically designed for shallow investigations. This unit excels at detecting voids and reinforcement in concrete floors and walls. It saves all scanned data, allowing us to conduct further analysis off-site using specialised computer software. This off-site data analysis is an essential part of our GPR investigations, producing detailed, easy-to-interpret images for clients and highlighting critical subsurface features.
- Ideal for shallow subsurface investigations.
- Detects voids and reinforcement in concrete.
- Off-site data analysis for more detailed insights.
- Saves data for further review and reporting.
Noggin 250MHz
Our Noggin 250MHz unit is specifically used for utility location. It’s perfect for detecting utilities like power lines, gas pipes, water mains, sewage, fibre optic cables, and more. This unit is frequently employed alongside field testing to ensure that drilling is conducted in safe and accurate locations. GPR utility locates are now becoming a standard requirement before any excavation or drilling, ensuring that costly and dangerous mistakes are avoided.
- Specialises in detecting underground utilities.
- Commonly used before excavation or drilling to ensure safety.
- Identifies power, gas, water, and sewer lines, as well as fibre and cable networks.
Applications of GPR
GPR is an invaluable tool across a wide range of applications, including:
- Pavement works: Detect voids or weak spots in roadways, preventing costly repairs.
- Land development: Assess subsurface conditions for future development projects.
- Residential and commercial projects: Identify buried utilities and assess concrete structures to ensure safe construction.
- Concrete structure assessment: Detect reinforcement, voids, and other features within concrete floors, walls, or bridges.
By identifying the “unforeseen” in your subsurface conditions, GPR can help limit unnecessary costs and mitigate risks, while providing essential data to better manage your projects.
