A Guide To Cured-in-Place Pipe Repair
Underground pipe repair is more cost-effective with trenchless solutions like CIPP point repair. Learn more with this guide to cured-in-place pipe repair.
How CIPP Point Repair Works
The CIPP process allows pipeline operators to repair a damaged pipe from the inside. This creates a versatile solution to damaged pipes in a wide range of shapes and sizes. CIPP pipe lining is jointless, seamless, and flexible enough to fit into the new pipe. At the same time, the material is strong enough to provide structural integrity while holding up against the products that flow through the pipeline. How do operators complete a CIPP point repair? This guide to cured-in-place pipe repair breaks the process down into two major steps: reconnaissance and installation.
Pipeline workers must first inspect the pipeline to locate the damage. Workers use cameras to televise the interior of the pipeline. This also shows workers any roots, dirt, or other debris that they will have to clean out before they can begin the installation process. Once pipeline workers have a clear image of the pipe and their workspace, they will take precise measurements of the pipeline and use this information to prepare the CIPP pipe lining and materials.
The installation process begins with pipeline workers folding the relining material around their point repair packer. Workers will then bundle the packer and liner together and tie the bundle with string, rubber bands, or other ties that will break once the packer inflates. Next, workers insert the packer into the pipeline. Once the packer is in place, workers inflate the packer to press the liner up against the pipe. Workers then use hot water, hot air, or another curing agent to harden the lining and effectively seal the damaged portion of pipeline. At the end of the process, workers deflate and remove the packer, and the pipeline is ready for service once more.
The Benefits of CIPP Point Repair
Buried pipes are difficult for workers to reach. Without solutions such as CIPP repair, workers would have to dig up the pipe and stop service while they cut and replaced portions. The ease and efficiency of CIPP point repair allows workers to complete a job in a single day. This minimizes service disruption and makes life easier for both end-users and pipeline owners.

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product. Please review our Warranty, Terms and Conditions.
Note 1: Mechanical and Molded Rubber Plugs are generally used for testing because fabricated Multi-Flex® style plugs may allow some seepage unless customized for a positive seal.
Note 2: We are constantly upgrading our products and while we try to keep the websites up to date it is possible more current specifications may be on a quote or confirming order. Images are typically representative and may not be an exact representation especially of the item size.
