Preventing concrete from spilling into waterway

[HSNIC]

I am involved in fixing a concrete bulkhead wall that is along a tidal water channel. The owner of the channel is sensitive to the construction. Over the bulkhead wall is an abandoned set of railroad siding and proposed building setback about 90ft from the channel.

The wall is in disrepair due to spalling. There are holes and crevices scattered througout along the face of the wall. As of now, the plan is to have these holes filled from a raft floating in the channel. Does anyone know of a way (or system) of applying concrete/grout to the wall without some of it spilling into the waterway?

Any special permits needed?

Have you studied the forces on this wall? Crack, crevasses and spalling would indicate the wall is no longer a structure but waste material. Permits may include Army COE, Watershed District. In some areas even a local appearance bd.

Grouting can be done without spilling any grout, not too easy but should be possible. Methods depend on the exact location.We provided a solution to grouting in a radiation contaminated area where the client was extremely concerned that none of the radiation contaminated grouted material would be released into the environment.Pump and return inside special bags or you can cover the area in fabriform material that will allow water to escape but not cement fines.Depends on what and where you are trying to grout.
