The method and apparatus for forming an encapsulation or encasement about a structural member that is particularly well suited for use in a marine environment is disclosed. A two component polymer system for protective and repair encapsulation is pumpable in two separate streams to the location of the structural member to be encapsulated. The two reactive components are combined in a static mixer immediately prior to being injected within the surrounding translucent jacket. By combining the reactive components immediately prior to use, premature set up is avoided and the resulting grout may be directed to flow upwardly in the jacket for enhancing final properties. By suitable coloring of the components, visual monitoring of the final mxing and distribution in the translucent form or jacket of the encapsulation material may be monitored. A field test for determining bond strength of the encapsulation polymer to the structural member is also disclosed.
