REPLACING DAMAGED PILE WITH NEW CONCRETE PILE
UNDER CONCRETE DECK
: Pile deterioration
or damage has been experienced
reduce the structural integrity of the section of pier. Concrete pile cap and
decking precludes replacing with timber pile.
Description of Repair: Cut a hole in the concrete deck between timber pile
bents. Drive new concrete pile. Cut the pile below the top of the concrete deck.
Form the capital under the deck, on top of the new pile. Cast the capital and the
new section of concrete deck (see Figure 6-8) including splicing in new
reinforcing bars. Epoxy coat bars where possible.
Application: Limited, mainly due to cost. If fixed structures are on deck, or if
deterioration is wide spread, this approach may not be practical.
Future Inspection Requirement: Same as with new concrete piles and concrete
