AN OWNER'S TROUBLESHOOTING GUIDE TO CIP LINING
Abstract:Cured-in-place (CIP) pipe lining is widely used for trenchless pipeline renewal, particularly for gravity sewers. Conventional design, quality control, and payment procedures have evolved and technical specifications incorporating these procedures are widely available. The conventional specifications provide an adequate basis for bidding and project administration when the success or failure of a liner installation is clearly evident, but guidance is generally limited for potential outcomes where the value of the installed product is in question. A lining installation is subject to a variety of possible defects, from the aesthetic and inconsequential to the operationally or structurally unacceptable. This paper presents guidance for the owner concerning what can go wrong, why it occurs, and the preventive or corrective measures that should be incorporated into contract documents to provide an appropriate level of protection.
