Utilities Innovation Project
• Developed by JFNDT in line with European legislation
• Identify and locate service pipes easily, without the need for excavation
• Rapidly differentiate between different types of service pipe
• Lightweight
• Quick to deploy
Lead discriminator
The inability to identify and locate service pipes easily, without the need for excavation, has resulted in higher than necessary levels of blanket phosphate dosing and high numbers of aborted visits on lead replacement programmes.
The lead discriminator is lightweight and fast to deploy. It is similar in appearance to a ground penetrating radar and requires no excavation nor connection to the service pipe. It takes between 30 seconds and 3 minutes to survey and analyse a typical service pipe.
Lead discriminator
A new approach to the acquisition and processing of 3D SONAR data has led to significant improvements in the analysis and reporting of volume and dispersal patterns of settlements within harbours, settlement tanks and storage facilities.
• Typical survey time : 45 minutes at high resolution
• Maximum Range : 40 metres diameter
• Maximum Operating Depth: 200msw (deeper on request)

Techniques• In-situ stress measurement in concrete by instrumented coring
• In-situ stress measurement in concrete by pressure compensation slotting
• In-situ stress measurement in steel tendons and reinforcement bars by controlled strain relief drilling
Testing and monitoring of concrete structures
• Specific structural defects identified during inspection
• Investigate known problems associated with common construction details (e.g. post-tensioning systems, concrete half joints)
• Insufficient load carrying capacity from assessment
• Construction operations may affect structure
• Changes in building use
• Postpone expenditure on strengthening/ reconstruction
• Monitor features that are difficult to inspect
Why monitor?
Testing and monitoring of concrete structures
Can justify safe delay of repairs, or avoid expense
Monitoring can tell you valuable information about your asset
Data remotely presented to clients requirements
We are experienced in providing bespoke systems for clients
