Electromagnetic detection is a non-invasive method used to locate underground utilities like metal pipes and live cables without the need for excavation. At Electromagnetic Detection, we use advanced electromagnetic location (EML) techniques to deliver fast, accurate results for projects across the UK.

Our electromagnetic detection services in Greater Manchester help engineers, planners, and contractors avoid costly damage, reduce delays, and maintain regulatory compliance. Whether for pre-design planning, site clearance, or utility mapping, our surveys provide essential underground insights safely and efficiently.

What Is Electromagnetic Detection And How Does It Work?

In Greater Manchester, Electromagnetic detection, or EML, is a proven method for locating metallic underground utilities using signal induction and tracing.

A transmitter induces an electrical signal onto a utility line, which is then picked up by a receiver. By following this signal above ground, surveyors can trace the path and depth of cables, metal pipes, and other conductive assets.

EML is often used in Greater Manchester as a primary tool in utility detection surveys, offering reliable results for a wide range of infrastructure.

What Types Of Utilities Can Electromagnetic Detection In Greater Manchester Locate?

Electromagnetic detection in Greater Manchester is a precise and non-invasive method used in electrical test and measurement to locate underground utilities containing conductive materials. This technique is essential for identifying:

• Live electrical cables – Enables the safe tracing of active power lines to prevent electrical hazards during excavation.
• Metallic gas pipelines – Detects underground gas pipes made of metal, reducing the risk of ruptures or leaks.
• Conductive water mains – Accurately locates buried metal water pipes to assist in maintenance or redesign planning.
• Telecom ducts with metallic sheathing – Identifies communication cables that incorporate conductive elements, ensuring system integrity.
• Tracer-wired non-metallic pipes – Makes plastic or composite pipelines detectable through integrated tracer wire technology.
• Vacant metallic conduits – Detects unoccupied metal ducts using signal clamps for future utility planning.
• Street lighting and control cables – Locates circuits powering lighting infrastructure when an active signal is applied.

Used widely in electrical engineering, electromagnetic detection supports safe excavation, asset mapping, and infrastructure development by providing accurate, real-time subsurface data without the need for disruptive digging.

How Much Does Electromagnetic Detection Cost in Greater Manchester?

Electromagnetic detection survey in Greater Manchester costs start from £400 to £800, while larger or more complex projects requiring CAD deliverables or GPS integration may cost more. These prices depend on factors like site area, utility density, and reporting requirements.

Pricing also considers whether active or passive tracing is required, the type of equipment used, and whether the service forms part of a wider PAS 128 utility mapping project.

When Should Electromagnetic Detection In Greater Manchester Be Used In A Project?

Electromagnetic detection in Greater Manchester should be used before any excavation, piling, or intrusive groundworks in a project. Electromagnetic detection identifies buried services during planning, design, and site risk assessments.

In Greater Manchester, electromagnetic detection is required before trenching, road crossings, or utility upgrades. Electromagnetic detection also supports reactive maintenance and fault location by tracing known or suspected underground services.

What Are The Advantages Of Electromagnetic Detection Over Other Methods?

Electromagnetic detection in Greater Manchester is highly accurate for metallic utilities, with quick setup and minimal disruption to site operations. It can be used on live or de-energised lines and provides immediate visual feedback to the operator.

It’s often faster than ground penetrating radar and excels in areas where services in Greater Manchester are known to be metallic or tracer-wired. It also aligns with PAS 128 methodology, making it a trusted first step in compliant utility survey workflows.

What Equipment Is Used In Electromagnetic Detection Surveys in Greater Manchester?

Electromagnetic detection surveys in Greater Manchester use a cable locator receiver, a signal generator (transmitter), and inductive accessories such as clamps or flexible tracers.

Electromagnetic detection equipment in Greater Manchester may include GPS receivers or total stations for georeferenced mapping. Electromagnetic detection requires frequency and mode adjustments based on utility type and site conditions.
