BEM™ (Broadband Electro-MagneticS), Non-Destructive Testing

BEM™ is a proven, global technique with several competitive NDT advantages.  Its accuracy for mapping corrosion and identifying discreet or localised flaws in ferrous infrastructures such as pipelines, storage tanks, ship hulls and a variety of objects has been independently verified and supported.  

It is also a truly non-destructive method, as it doesn’t require the removal of linings or coatings for inspections and subsequent refurbishment.  Rock Solid Group has BEM™ tools for both internal and external scanning for pipes from 150mm (6-inch) up to beyond 2.4 metre diameter pipelines (96-inch). 

BEM™ before Bust!

Pipe failures are happening regularly in major cities around the world on almost a daily basis as aged infrastructure approaches the end of their manufactured remaining life.  Utilities around the world with asset management responsibilities have a growing awareness of the need to BEM™ before Bust!

BEM™ Advantages! 

BEM™ is available in different configurations like the simple Hand Scanning Kit (HSK) to complex remotely operated submersible devices – applicable to any diameter or shape.  You can engage the full range of specialised services, rent/buy the equipment or become a licensee.  Certified training also available.

There are numerous benefits and advantages of BEM™ over other technologies for measuring wall thickness.

BEM™- Industries / Regions / Licensees / Customers

Into its third decade, BEM™ has become the technology of choice for a diverse range of customers across the Water, Wastewater, Gas and Nuclear power, Mining and Manufacturing Plant industries.  

Our BEM™ customer base spans the globe and is serviced both directly and via our BEM™ Licensees and Strategic Partners.


Our RSG AIM is an artificial intelligence tool that has been developed on the basis of Bayesian logic to provide a client with:

  • A stand-alone current evaluation of a pressure pipe network (A system health check)

  • As a tool to determine if invasive is needed and focus such investigation to areas determined by the audit data with recommendations for appropriate techniques

  • As a tool to identify replacement, remedial and repair works and where appropriate possible methodologies

  • Recommendations for on-going inspection, investigation both invasive and non-invasive

The tool also creates the basic information and methodology for ongoing condition assessment of the asset.

EXCOR™ Geochemical Soil Sampling

Soil samples are collected and sealed in PVC containers for shipping to our preferred soil testing laboratory.  

The laboratory output results summarize the following:

  • A brief description of the key characteristics of the soil

  • Soil resistivity (natural) (Ωm)

  • Minimal resistivity (Ωm)

  • Moisture (%)

  • pH

  • Redox potential (mV)

  • An overview of the soil samples alkalinity, aeration and level of corrosivity to the material type of the asset being inspected.

Ultrasonic Testing (UT)

UT ‘pinpoint’ position wall thickness data is usually collected on site both for cross-correlation to BEM™ as a quick and easy additional data source.  UT has limitations with rough, uneven, dirty or coated surfaces.  It also has some shortfalls when testing Cast Iron and Ductile Iron assets for thickness readings, due to the physical and metallurgic properties of these material types.


One of the learning from the Critical Pipe5-year study was that leaking pressure mains is a pre-warning for a potential burst.  Acoustic Leak Detection (ALD), is a common condition assessment tool.  Rock Solid Group has completed a number of pipeline condition assessment projects that included a step for ALD.
