Abstract : Sheet piles, used as retaining walls, wharfs, and piers, are typically made of unprotected carbon steel (CS). This type is affordable and the general corrosion rate (wastage) is predicable. Despite the long and successful use of CS sheet pilings, there are reports of localized corrosion of CS pilings that have been identified as microbiologically influenced corrosion (MIC) ie. corrosion that is a result of the presence and activities of microorganisms. Microorganisms can produce localized attack including pitting, enhanced erosion corrosion, enhanced galvanic corrosion, stress corrosion cracking, and hydrogen embrittlement of CS. Microorganisms do not produce a unique corrosion morphology in CS that could not be produced abiotically.
