Abstract

See full text

A renovation liner is installed in a pipework. More particularly, an end of the renovation liner is closed by an elastic end piece. The renovation liner is impregnated with a hardening impregnating agent. The renovation liner, together with its end piece, is slipped into a position in the pipework to be renovated. A pressure is provided and maintained in a space formed by the renovation liner and the elastic end piece in order to press the renovation liner against walls of the pipework until the impregnating agent of the renovation liner has hardened in shape. The elastic end piece is removed.
