Abstract : The patent is about a resin solution comprising a sea-water-insoluble, nontoxic resin-plasticizer system dissolved in a sea water soluble solvent. Also, an antistatic agent is contained in the solution to enhance spreadability. The resin solution is fed through an extrusion head disposed underwater and in close proximity to the sediment of the ocean floor. The resin-plasticizer system of the solution has a relative high specific gravity greater than 1.0 so that, when the system precipitates in the sea-water, it drops onto the sediment. Preferably, the extrusion head is moved along at a controlled rate to form a continuous sheet of a desired thickness.
