Feasibility Study

Non Destructive Testing (NDT)



As experts in cathodic protection and electrochemical repair CCSL are perfectly placed to advise our clients on the most appropriate form of repair for their structure.

Feasibility studies allow us to collect data through non destructive testing, trial specific treatments and analyse the practical issues and requirements of your structure.

A typical feasibility study would consist of the following:

  • Assessment and prioritisation of repair requirements
  • Collection of parameters required for the design of credible repair options
  • Trial and performance assessment of repair options
  • Budgeting of suitable repair schemes

Following successful trial and selection of repair techniques CCSL can offer a service to design, install implement the selected repair solution for our clients.

Non Destructive Testing (NDT)

CCSL can provide services to implement and interpret a range of non-destructive testing and sampling techniques.

Through non destructive testing it is possible to determine many factors which may contribute to the proliferation and initiation of corrosion in concrete, masonries, soils and waters. The correct combination of techniques allows us to determine the likely cause, extent and future risk of corrosion and what this means to your structure.

CCSL can provide services relating to following:

  • Hammer Tap Sounding Survey
  • Half-cell Potential Survey
  • Resistivity Survey
  • LPR Measurement (Corrosion Rate)
  • Determination of Cover Depth
  • Chloride ion content sampling and determination
  • Carbonation Testing
  • Petrographic Analysis
  • Water and Cement Content for Concrete

CCSL are UKAS Accredited to ISO/IEC 17025:2017 registration number 10830 (click here to see our certificate) to undertake the following activities:


CCSL have an extensive track record of survey works applied pipelines within the oil, gas, petrochemical and utilities industry worldwide.

Employing Close Interval Potentials Survey (CIPS) and Direct Current Voltage Gradient (DCVG) techniques CCSL can provide detailed information relating to the performance of existing cathodic protection systems and the integrity of coatings applied to pipelines.

CCSL have been employing these techniques for over twenty years to the satisfaction of blue chip clients throughout the world.
