A conduit liner system comprising a length of flexurally resilient liner material (10) having first and second ends (11, 12) a first radius of curvature greater than the radius of curvature R3 of the inner surface (17) of a conduit (16) to be lined and when elastically deformed a second radius of curvature R2 smaller than that of said inner conduit surface (17) and a restraining means adapted to hold said liner at said radius R2, and wherein release of the restraining means permits said liner (10) to return to said first radius of curvature until prevented by interaction with inner conduit surface (17) provided that ends (11) and (12) overlap. |
