LEAK TIGHT JOINT AND METHOD, AND LEVELLING POLYMER FOR PROVIDING A SMOOTH SURFACE ON A CONCRETE BODY BEING JOINTED

摘要

A self-levelling polymer (30) including a thermosetting resin, is applied to the surface (20) of a concrete body (10) to give a smooth join surface (60) between the concrete body and another body. A backing strip (40) on the periphery of the concrete body acts to contain the polymer. A sealing device, for example a gasket, may be placed between the bodies and the bodies coupled together to provide a compressive force on the sealing device. The joint is used in containment vessels that are pressurised or under vacuum.
