1. Introduction to GPR Survey

Ground Penetrating Radar (GPR) is a non-invasive, advanced geophysical technique used to map subsurface structures and detect underground utilities, voids, and anomalies. At Bhoojal Survey, we specialize in providing accurate, reliable, and efficient GPR survey services tailored to meet the unique needs of our clients.

Ground Penetrating Radar Survey is mostly used for detecting underground pipelines, both metallic and non-metallic, installed beneath earth surfaces. In correlation with leak detection instruments, pipeline leakage detection can be traced.

Why Choose GPR Survey?

• Versatile: Suitable for various applications, including metallic pipe detection, non-metallic pipe detection, water pipeline detection, pipeline leakage detection, utility detection, concrete inspection, and archaeological surveys.

2. How Does GPR Work?

GPR works by emitting electromagnetic waves into the ground and analyzing the reflected signals. We transmit electromagnetic waves into the ground using a sender antenna. It hits objects, such as utility lines buried inside the ground, and the receiver antenna records the signal.

A lower frequency antenna penetrates deeper, while a higher frequency antenna penetrates shallow depths. The depth of the object depends on the time taken to reflect signals. Larger objects produce wider hyperbolas, while smaller objects create tighter ones. Deeper objects generate wider hyperbolas due to the increased travel time of the signal.

As the antenna moves over an object, the vertical distance (time of the reflected signal to arrive at the antenna) decreases until the antenna is above the object, and it increases as the antenna moves past the object. Therefore, a single object will appear in the GPR output data as a hyperbola.

Here’s how the process works:

1. Radar Pulse Emission: A GPR antenna emits electromagnetic waves into the ground.
2. Signal Reflection: The waves reflect off underground objects, such as pipes, cables, and voids.
3. Data Collection: The reflected signals are captured by the GPR system.
4. Data Analysis: Specialized software processes the data to create a detailed subsurface image.
5. Object Identification: Underground objects and anomalies are identified based on the reflected signals.

Advantages of GPR

• Accurate Object Location: Pinpoints exact locations of underground objects without excavation.
• Time-Efficient: Provides real-time data, reducing downtime.
• Cost-Effective: Minimizes project costs by avoiding unnecessary digging.
• Safe: Non-destructive method ensures safety for workers and the environment.

3. What is a GPR Survey?

A GPR survey is a geophysical method that uses high-frequency electromagnetic waves to map subsurface structures. It is widely used for detecting underground utilities, pipeline detection, and pipeline leakage detection. GPR works by emitting radar pulses into the ground and analyzing the reflected signals to create a detailed image of the subsurface.

Key Features of GPR Survey

• Non-Invasive: No digging or excavation required.
• High Accuracy: Provides precise location data for underground objects.
• Real-Time Data: Immediate results for quick decision-making.
• Versatile: Works on various soil types and materials, including concrete, asphalt, and soil.
• Depth Penetration: A lower frequency antenna penetrates deeper, while a higher frequency antenna penetrates shallow depths.

4. Applications of GPR Survey

GPR surveys have a wide range of applications across industries. Here are some key uses:

Utility Detection

• Locating Underground Utilities: Detects pipes, water pipelines, metallic and non-metallic pipelines, gas pipelines, and leakage detection cables to prevent damage during excavation.
• Mapping Utility Networks: Provides detailed maps of underground utility networks for planning and maintenance.

Concrete Inspection

• Rebar and Post-Tension Cable Detection: Identifies rebar and post-tension cables in concrete structures.
• Void Detection: Detects voids and cracks in concrete slabs and structures.

Archaeological Surveys
