A resin system for impregnating a liner element made of a resin-absorbing material for rehabilitating a pipeline. In addition, the invention relates to a method for lining a pipeline by means of a liner element of resin-absorbing material and a rehabilitation device for performing the method. The resin system according to the invention comprises three components (A), (B) and (C) wherein component (A) is a reactive resin, wherein component (B) is an additive, wherein component (C) comprises nanoscale bodies, and wherein component (C) can be excited by ultrasound, UV radiation or microwave radiation to trigger the curing of the resin system. In the method according to the invention and the rehabilitation device according to the invention, a mobile curing device is used, which is passed through the inverted liner element.
