This article will look at three standard pipe lining methods: Slip-lining, Spray-in-place pipe, and cured-in-place pipe. Learn more about each method’s work and what to expect during a project. Listed below are the pros and cons of each technique. We’ll also cover tips to make the process go smoothly. To learn more, refer to a pipe lining company.

Spray-in-place pipe

SIPP is not a novel concept; it was used in the early 1900s with hand-applied cement mortar. Several decades later, cement mortar was sprayed into larger diameter pipes and, finally, smaller diameter pipes. Spray-in-place pipe lining is a new method for repairing leaks in sewer lines. It’s a quick and cost-effective way to fix your sewer line. 

The process begins with the creation of a small access point. Then, the lining is poured or sprayed into the existing pipe. Once the lining has cured, it hardens into a brand-new pipe. Polymers and epoxies, which mix the resin and a hardening agent in a liquid form until combined and allowed to react chemically, are also used for SIPP. When the reaction is finished, they become 100 percent solids. Epoxy comprises a resin called bisphenol A and a hardening ingredient called epichlorohydrin. The reaction is started by adding a catalyst and heating it to extremely high temperatures. However, some epoxies’ setting time necessitates using a different service connection.

Cured-in-place pipe

The term cured-in-place pipe refers to a jointless, seamless method of pipe rehabilitation. This method has numerous advantages. First of all, it is a trenchless process. Second, it is a faster and cheaper option than traditional methods. Third, it does not require the excavation of a trench to complete the installation. And finally, it can be performed in the exact location as the original pipe.

Pipe Lining

CIPP pipe lining can be installed on pipes of any diameter from six to nine feet. And it is highly versatile, as it can be used for everything from short-liner repairs to full-system repair installations of more than 2000 feet. CIPP lining requires fewer repairs and can be applied to pipes up to 36 inches in diameter. It is ineffective in repairing a blocked pipe due to water pressure, but it can be used in certain situations.

The advantages of CIPP over other methods are that it provides structural pipe relining within the existing pipe and can extend the life of the liner by up to 50 years.


Slip-lining in pipe liners involves inserting a PE100 liner into an existing host pipe. The new pipe fits into the host, which should be free of bends and deformities. In a typical installation, this will require little to no digging. It’s also a safe, long-term solution for most applications. 

The most common application for slip-lining involves pulling a new pipe inside the existing one. The new pipe is inserted into the old pipe and reduces its diameter. It covers any connections that would otherwise have to be cut out later. Self-hardening epoxy is applied to the ends of the new pipe to prevent leakage from the old pipe. The most recent technique for pipe lining uses this technique.
