Abstract
A piling-jacket system (10) and method involves a piling jacket (12) having a side, vertically-slit, open port arrangement (14) with an internal flap valve in the shape of a duct (48) attached to a cord (56) which extends externally of the piling jacket to positively force the duct flap valve closed. The piling jacket system includes a steel band (84) at the top of the piling jacket which clamps the piling jacket in a notch (86,88) cut in a piling (80) to be repaired with the piling-jacket system. When the piling jacket is thusly hung from the piling, the lower portion of the piling jacket, pulling down on the vertically-slit open port tends to close the open port. A portable, rigid, access tube (66) is placed through the vertically-slit open port to hold it open for the insertion of a grout-supply hose.
