Abstract
A tubular structure is reinforced or reinstated by providing a reinforcing layer in its interior in spaced relation to the existing structure so that a cavity is formed. Plastics or polymer material, preferably a compact elastomer, is injected into the cavity and cures to bond the existing structure and reinforcing layer together so that shear forces are transferred and the reinforced structure behaves as a composite body.
