<p>The invention provides a method and apparatus for lining a conduit (1) such as a pipe with deformable plastics liner pipe. The method comprises: (i) deforming the liner (7) along its length to a cross section with reduced external dimensions relative to the dimension of the undeformed liner, (ii) binding the liner by helically winding an elongate flexible element around the liner along its length to maintain it in said deformed cross section; (iii) drawing the bound liner into the conduit to be lined; (iv) releasing the binding to allow the liner (7) to assume a cross section substantially corresponding with the internal cross section of the conduit (1).</p> |
