Many waste-water system operators are unsure of what can be achieved by main sewer repair methods and what quality is attainable. Twelve different techniques from the three groups of methods: “Injection/grouting + injection methods”, “Short-liners” and “Internal sleeves” have been comparatively tested under defined and replicable conditions using the IKT Comparative Test “Repair methods for main sewers”. The principal focus was the testing of the techniques in IKT test rigs under conditions approximating to actual practice. The IKT Comparative Test provides reliable and impartial information on the quality of the techniques tested and statements concerning the general suitability of the individual techniques and method groups
