A flooding and grouting valve is provided for use in an offshore jacket. The valve mechanism includes a flood valve portion including an opening to ambient water and a rotatable gate for selectively covering and uncovering the opening. The valve mechanism also includes a check valve mounted on the gate for rotation therewith. The check valve includes a passage which communicates with the interior of the gate, whereby the check valve and gate together form a passage for conducting grout. The check valve is to be connected to a grout supply line such that opening of the check valve is opened by the action of incoming grout. A conduit-type, drive rod is rotatably mounted on the jacket, is connected to the check valve, and serves as a grout conduit. The rod extends to an upper end of the jacket whereby an operator at the water surface may rotate the check valve, and thus the gate, to open or close the flood openings.
