GPR Survey in Chhattisgarh

Construction and infrastructure development works may sometimes go beyond what we see on the surface level. The presence of underground cables, pipes, drainage, reinforcements, underground structures and cavities may pose unforeseen difficulties during excavation and development. Thus, proper knowledge of subsurface environment becomes necessary before undertaking any construction activity. GPR Survey in Chhattisgarh serves as a non-destructive way of studying the subsurface environment without undertaking extensive excavation at once. GPR Technology utilizes electromagnetic waves to identify and map subsurface objects enabling construction professionals, contractors, infrastructure developers, and project owners to know the possibilities that may exist underground before starting the process.

ASurvey offers GPR along with some other surveying solutions such as geotechnical investigation, DGPS, mine survey, pipeline route survey, topographic survey, geophysical survey and soil testing.

What is GPR Survey?

GPR, which stands for Ground Penetrating Radar, is a method of geophysical surveying that is done to study the subsurface conditions. In this method, an electromagnetic pulse is transmitted into the earth’s surface, which gets reflected back by various objects present in the subsurface.

There are some of the features that can be investigated using a professional GPR Survey in Chhattisgarh such as:

• Underground electricity lines
• Water and sewer pipes
• Telecommunication ducts
• Buried utility lines
• Foundations made of concrete
• Rebar
• Cavities
• Underground structures
• Subsurface anomalies

The depth and level of detection would vary depending upon soil type, moisture content, material type, frequency of the antenna, and target features.

Importance of GPR Survey in Chhattisgarh

There is considerable construction, industry, mining, road and pipeline projects and infrastructure development in Chhattisgarh. The cities and industrial zones like Raipur, Bilaspur, Durg, Bhilai, Korba and others have different kinds of pre-existing infrastructures and ground conditions.

Prior to excavation, drilling, laying foundations or constructing roads, there is a need for project management team to be aware of what exists underground.

The GPR Survey in Chhattisgarh can assist in conducting such initial investigations, which will be able to aid project managers with better planning of the excavation, foundations, utilities and structural changes.

ASurvey operates from Korba, Chhattisgarh, and includes mining and minerals projects, construction and infrastructure projects, industrial and plant projects, dams and hydro projects, and roads and pipeline projects under its sectors.

Applications of GPR Survey

1. Buried Utility Detection

Through GPR surveys, the detection of underground utility systems like pipelines, cables, conduits, and drains can be done to avoid any problems in excavation.

2. Site Investigation Before Construction

Before embarking on any construction activity, additional investigation into what exists in the soil beneath can be conducted using GPR survey technology. This is especially applicable in developed sites where there could be previous buildings or buried features.

3. Reinforcement and Concrete Feature Detection

GPR surveys can be used to detect reinforced and embedded features in concrete buildings. Information gathered through such surveys can be used during renovation, repairs or construction of any feature.

4. Road/Pavement Investigation

In road construction and rehabilitation, investigation of the subsoil can be conducted using the GPR technology. This helps in detecting voids or anomalies under the road/pavement structure.

5. Detection of Cavities and Voids

The existence of underground cavities or voids can pose serious challenges when constructing or building infrastructure on the land. Through GPR surveys, such areas can be detected and investigated.

Process of GPR Survey

A professional GPR Survey in Chhattisgarh usually involves the following process steps.

Step 1: Analysis of Requirements for the Project

The survey team studies the objectives of the project, site conditions, relevant drawings, and locations to be surveyed.

Step 2: Preparation for the Survey

The survey location, the paths for scanning, equipment, and proper antenna frequency are decided based on the site and the requirements of the survey.

Step 3: Performing GPR Scanning

The GPR equipment is used to scan the survey area to receive the reflection signals of electromagnetic waves from the underground materials.

Step 4: Data Processing

The acquired data is processed using the appropriate digital techniques to obtain important reflections.

Step 5: Data Interpretation

The survey professionals interpret the data to identify potential utilities, structures, voids, reinforcement, and other features detectable by GPR.

Step 6: Report Preparation

The results of the survey can be shown through the use of maps, profile, drawings, images, observations, and technical reports depending on the requirements of the project.

Geophysical survey using GPR in combination with Geotechnical investigation

While GPR is a useful technique for initial studies, it cannot substitute every type of geotechnical test that needs to be carried out. GPR gives non-destructive information about all detectable subsurface objects, while geotechnical investigation gives direct information about soils and rocks.

Thus, when carrying out GPR survey in Chhattisgarh and conducting proper geotechnical investigation, one gets better results regarding ground conditions.

In case of foundation works, further investigations such as boring, soil samples, SPT or pile tests etc. may be required according to the project design. ASurvey provides geotechnical investigation and soil testing as one of their services.
