What Is a GPR Survey?

A GPR survey, or Ground Penetrating Radar survey, is a method we use to explore the subsurface structures of an area without any digging. It works by sending radar pulses into the ground and capturing the echoes that reflect back.

These radar pulses are generated by equipment such as a GSSI SIR 4000, an industry-standard GPR data acquisition system, which offers high-resolution images of the subsurface. The survey can identify buried utilities, pipes, voids and changes in material, such as soil and rock layers, providing vital information for construction and archaeological purposes.

This data is essential for urban development projects, allowing us to map below-ground hazards and reduce the risk of costly on-site surprises. We follow BS EN 302066-1:2019 standards to ensure precise and safe detection.

Our surveys typically cover depths of up to 10 metres depending on the ground conditions. The data we gather helps manage project risks and planning more effectively.

How Much Does a GPR Survey Cost in Cheshire?

The cost of a GPR survey in Cheshire typically ranges from £1,000 to £3,000 per day, depending on the size and complexity of the project area. The price can also fluctuate based on factors such as terrain type, with more uneven or rocky surfaces potentially requiring additional equipment like shielded antennas.

The depth of survey required can affect the choice of radar frequencies and the time taken: shallow surveys might use 400 MHz antennas for higher resolution, while deeper investigations may need 200 MHz antennas. Site accessibility, like urban environments or restricted zones, can also impact survey logistics and costs.

We adhere to industry standards like PAS 128 for utility detection, ensuring reliable data collection. We provide detailed quotes after assessing your specific needs.

What Types of GPR Surveys Are Available in Cheshire?

We offer a range of GPR survey types in Cheshire to suit various applications, using specialised equipment and methodologies for each task.

Utility Detection: Using GPR with multi-frequency antennas, we can locate pipes, cables, and other underground utilities. This step is essential for construction projects to prevent damaging critical infrastructure during excavation.
Void Detection: By employing GPR with varying antenna frequencies, we can effectively identify sinkholes or voids that may compromise structural integrity. This is particularly important for roadways and building foundations to ensure safety and stability.
Concrete Scanning: Our surveys use high-frequency GPR to assess concrete structures for embedments like rebar, post-tension cables, or defects. This process helps in renovation projects and safety assessments of buildings.
Archaeological Surveying: With non-invasive GPR techniques, we map historical sites to preserve their integrity while uncovering artefacts and structures. This approach is invaluable in heritage conservation efforts.

Each type is specifically designed to deliver precise results for different needs and sectors, allowing informed decision-making for our clients. Contact us to determine the best survey type for your project in Cheshire.

What Are the Benefits of GPR Surveys in Cheshire?

GPR surveys offer several benefits for your projects in Cheshire:

Non-invasive Exploration: Avoids the need for destructive digging, preserving the site's integrity. This is particularly useful for protecting historical sites or when working in urban areas with complex subterranean infrastructures.
Accurate Mapping: Provides clear images of subsurface features with precision down to centimetre levels, which aids in detailed planning and design. Our equipment meets the regulatory standards such as BS EN 302066 for quality assurance.
Risk Management: Helps identify potential hazards, like voids or unmarked utilities, before construction begins. This reduces the risk of delays and unforeseen costs, enhancing project safety and planning efficiency.
Versatile Applications: Suitable for construction, archaeology and environmental studies, GPR can be used to identify archaeological artefacts or assess soil contamination levels. It's adaptable across various environments, including wetlands and rocky terrains.

Frequently Asked Questions

How Long Does a GPR Survey Take?

A typical GPR survey can take from a few hours to several days, depending on the site size and complexity. We aim to complete surveys efficiently while maintaining accuracy.

Is GPR Survey Safe?

Yes, GPR surveys are safe as they use low-energy radar waves. This method poses no harm to the environment or people on site.

Do You Offer Services Beyond ST7 2?

Yes, we provide GPR survey services beyond the ST7 2 area. Our team covers a wide range of locations, ensuring you receive our support where needed.

What Do I Need to Prepare for a GPR Survey?

Ensure the survey area is accessible and clear of obstacles. Provide any existing site plans or utility records to help optimise the survey.

Can GPR Surveys Detect All Subsurface Conditions?

While GPR is versatile, it may have limitations in detecting materials that heavily absorb radar waves, such as clay soils. Our team advises on the best methods for your specific project needs.
