ABSTRACT:
A weakened underwater section of deteriorating pile is provided with a concrete splint. One of two companion seal members is first installed below the weakened section. A split tubular form is then installed about the section. The lower end of the form provides the second of the companion seal members that engages beneath the first seal member. The form is supported from above as water is pumped from the form. The buoyant upthrust moves the companion sealing members into firm sealing engagement. After the suspension for the form is adjusted, concrete is poured into the nearly dry form. The concrete mix is not compromised by contamination with seawater and a structurally sound splint is formed.
