The rehabilitation of manhole top sections forms part of drain maintenance work. In order to adjust and replace manhole top sections, considerable efforts are more necessary than ever because, in comparison with former times, especially high demands are placed on the evenness of the road surface which, as a result of the heavy traffic, is subjected to increased strains and stresses. This paper shows the results of a research programme. The target of the project was to evaluate substantial examinations of different rehabilitation methods for manhole covers. The large number of damages to manhole covers shows that there are weak points in rehabilitation methods. To find these weak points was an additional point of the research programme. The examinations demonstrated the principal failures of a lot of rehabilitation methods. On the whole the mistakes were found to be the use of inappropriate materials and the methods used on site. Recommendations are made for improvement of the rehabilitation methods and to heighten the duration of the use of rehabilitated manhole covers.
