Corrosion Analysis
Is rust and corrosion impacting the structural integrity of your tower?

Stop wasting valuable resources on failed rust and corrosion remediation attempts.

Every year, tower owners spend thousands of dollars trying to stop rust and corrosion from destroying their asset WITHOUT knowing the root cause. Its just an expensive Band-Aid. The most common attempt to remediate includes removing surface rust with a wire brush or grinding wheel and finishing with cold galvanizing compound. Unless corroded metal is properly addressed, painting over it encapsulates the corroding species and encourages further degradation of the underlying metal AND the finish painted layer.

In an effort provide a resolution to this problem, Waterford can provide a comprehensive assessment of the tower structure, components and foundation which includes the following:

  • Detailed site assessment
  • Component condition evaluation
  • Coating condition evaluation
  • Corrosion mechanism identification
  • Failure analysis (root cause)
  • Remaining life assessment (environmental impact?)
  • Performance Testing
  • Accelerated corrosion testing
  • Service environment simulations

 

 

 



Our experts can determine the root cause of corrosion failure, devise a mitigation strategy or conduct a remaining life assessment

 

  • Provides visibility into remaining life expectancy of tower asset based on scientific approach versus subjective guess work
  • Allows a proper remediation solution to be implemented as
    opposed to solely the typical “scrape & paint” method used
    by most remediation vendors
  • Using empirical data and a scientific approach adds valuable
    insight into the engineering process and leads to a significantly more accurate structural analysis

 

 

 

Using an electron microscope our experts were able to conclude that the corrosion affecting this structural bolt had not only penetrated deep beneath the metal surface, but had literally jumped. This is known as "Sporadic Internal Corrosion.

Unless addressed prior to reaching this level of corrosive degradation, there is literally NO way of preventing compromise to the structural integrity of the metal.

 

 

Diagnosing Corrosion Mechanisms

Waterford's experts understand that determining the root cause of the corrosion is critical to conducting Remaining Life Assessments. When a propert evaluation is peformed, a variety of factors are considered including:

 

  • General/Uniform corrosion
  • Galvanic and stray current corrosion
  • Intergranular and stress corrosion cracking
  • Crevice and Pitting corrosion
  • Microbiologically-Influenced Corrosion (MIC)
  • Environmentally assisted cracking
  • Corrosion fatigue
  • Fretting wear/oxidation
  • Particulate induced erosion corrosion or impingement attack

 

 

Proactively completing a comprehensive corrosion assessment is the ONLY way of accurately determining the cause and rate of corrosion to the tower steel, concrete and site components, as well as estimating the life that remains with or without proper remediation.

Investing in remediation only efforts may save the tower owner money, but ONLY when considering the first remediation attempt. Statistically, most of the towers that undergo traditional remediation tend to require repeat remediation efforts within 3-5 years and sometimes less depending on the location and environment. A comprehensive corrosion assessment combined with proper remediation saves the tower owner significantly over the long term and offers a permanent solution to the rust and corrosion problems that plague tower owners and compromise the value of their asset(s).
