GPR Survey in Hampshire

1.What is Ground Penetrating Radar (GPR) survey in Hampshire?

Ground Penetrating Radar (GPR) survey is a non-invasive geological method that uses radar pulses to image the subsurface. It involves transmitting radio waves into the ground and recording the reflected signals from underground structures.

Ground Penetrating Radar (GPR) survey in Hampshire can detect:

• Utilities
• Archaeological features 
• Faults in concrete floor slabs
• Voids and sinkholes
• Buried obstructions
• Rebar 
• Geological layers
• Under floor heating pipes
• Post tension cables
• Tree roots
• Bamboo rhizomes 
• Chimney flues

Our Ground Penetrating Radar (GPR) surveys in Hampshire are reliable and cost efficient.

2. What is the cost of Ground Penetrating Radar (GPR) survey in Hampshire?

The cost of a GPR survey in Hampshire is evaluated on the project-to-project basis. However, since our company is located in Hampshire the cost of your survey will not include additional charges like travel and overnight stay. 

3. Why would I choose GPR survey in Hampshire?

Hampshire, thanks to its proximity to our capital is often a place where Londoners move to escape fast-paced life. This influx of professionals boosts region’s attractiveness from private developer perspective. Choosing GPR survey in Hampshire for detecting utilities will keep your building site safer for employees and lower the risk of accidental damage to existing underground pipe and cable system. 

Hampshire is also valuable region from archaeological point of view. The archaeological findings in Hampshire were so significant that the County established Hampshire Field Club and Archaeological Society to recognise its heritage. Archaeological GPR surveys in Hampshire help to put a new light on already discovered sites as well as discovering new ones.

4. How GPR survey in Hampshire is performed?

Ground Penetrating Radar (GPR) surveys in Hampshire, as in other locations, typically follow a systemic process to ensure accurate subsurface imaging. Below is a general outline of how a GPR survey is conducted:

-Preparation and planning- this step includes site assessment, either in a form of a site visit or online research. Based on compiled information about terrain, obstacles, and any potential interference sources, a survey objective is clearly defined, and the area can be surveyed with confidence.

-Equipment setup- The choice of antenna frequency/ frequencies will depend on the desired penetration depth and resolution; lower frequencies penetrate deeper but provide less detail, while higher frequencies offer more detail but shallower penetration. The equipment will be calibrated for the specific site conditions like eg. soil dielectric constant.

-Data collection- typically area is scanned in an orthogonal grid or using GPS for accurate positioning.

-Data processing- in the first instance, the recorded data is transferred to a computer for detailed processing. In our advance GPR software, we will apply filters to remove noise, correct for signal drift, and enhance the signal-to-noise ratio. 

-Interpretation- at this step we will analyse the data and identify and interpret significant reflections that indicate different subsurface structures or materials eg. utility lines, voids, archaeological features). All findings will be compiled into an AutoCAD drawing.

-Reporting- our findings and interpretations will be discussed in a detailed report, which will be issued together with an AutoCAD drawing. We will also provide recommendations based on the survey results; the recommendations may include areas for further investigation or specific actions if utilities or hazards were detected.
