SR-6: COATING/CATHODIC PROTECTION OF STEEL SHEET PILE WALL
Problem:
Sheet pile wall has surface deterioration. Protection against further
corrosion is required.
Description of Repairs: Two procedures provide corrosion protection for steel
sheet piling:
Coatings. See Paragraph 3-4.3.1 (Submerged and Splash Zone). See
Figure 8-6.
Cathodic Protection: For sacrificial anode system, weld or bolt anodes
below low water on the steel. Determine size, type, and spacing of anodes to suit
structure and environment. A low resistance electrical connection between
adjacent piling must be made (see Figure 8-6). For impressed current systems,
place anodes off the face of the sheet pile wall.
Future Inspection Requirement: Increased inspection may be required,
particularly in areas where ice may be present, in order to detect signs of
abrasion of the mastic or removal of the anodes and renewed corrosion of the
sheet piling.
