Abstract: A concrete slab or a tubular concrete pipe is provided with a wall surface or liner to protect the concrete member from marinefouling organisms. The surface or liner incorporates an expanded shale aggregate, which aggregate has been impregnated with chemicals toxic to marine organisms. The toxic material will leach out very slowly over a long period to provide the desired protection. Such protective surfaces or liners are readily removable and can easily be replaced when the toxic chemicals are completely leached out.

Abstract: Plastic ropes composed of polyethylene and polypropylene strands exposed to high hydrostatic pressure materially increase in tensile strength without a corresponding increase in strand diameter.
