    Being that the diesel supposedly soaked into and through the cement, wouldn't a possible solution be to put the effected area under vacuum with a bleeder material? Very similar to a vacuum bagging setup? It would seem that doing this with some kind of fabric to absorb the extracted diesel would be a decent solution, followed by degreasing.

    I don't think diesel will soak through cement, It has to have cracks hair line or not.

    Im not saying its dangerous either or that the hull is weaker -it depends on how big the area is .. Knocking it out and filling may be a weaker job than it is already.

    Im not an expert on cement boats.

    Good reparations on ferro cement are made with an epoxy mortar which is stronger that any cement mortar for ferro. Normally diesel would not go through a well cured mortar unless there are too much polyester microfibers in the mix or air bubbles, so it's very likely that the mortar is fractured. The diesel will follow also the path of the wires of the mesh, maybe galvanized. Diesel fuel and zinc are totally incompatible...
