What is trenchless pipe repair and how does it work?

SPT Installing CIPP pipe liner to repair pipe

Trenchless pipe repair, also known as cured in place pipe (CIPP) lining, is a modern and cost-effective alternative to traditional excavation repair methods of the past. 

Traditional pipe lining and repair is costly and requires more time and resources than trenchless repair and lining. It also requires more manpower and, typically, more headaches. 

That’s why some companies, like SPT Ohio, have skipped past the messy and expensive pipe repairs of yesterday and instead fix your sewer pipe problems without even having to dig up your yard or add any new pipes. 

That’s right – no digging and no damage to your property. So how do we make it happen? Well, let us tell you. 


It all starts with a camera inspection to check for any root intrusions, cracks, leaks, or blockages. Then any debris is removed with a powerful Hydrojet, leaving your pipe free of any obstructions.


The bladder that will inflate the liner later is prepared. After that, a 2-part epoxy resin is mixed and cured into a custom-made, flexible, felt lining.

Once the epoxy has been poured into the liner, it is wetted out. This process allows the epoxy resin to be absorbed into the felt liner, turning it blue and making it nearly ready for placement. After preparing the epoxy, the outside of the liner is scored to ensure that the epoxy will adhere to the inside of your damaged pipe. 

A plastic sheet is then blown into the liner, followed by the already-prepared bladder. The plastic helps allow the bladder to be more easily maneuvered. 

Once the bladder is placed into the liner, it is taped in half for easier transportation and placement in the damaged pipe. 


Using an access point already on your property, the liner is then fed through your pipes, covering all cracks and failing sections within the pipe. 

Once everything is in place, the bladder is filled with air and left to cure in place for 3 to 4 hours. Once the “new pipe” has cured, the bladder is removed and one last camera inspection is done to make sure there are no issues with the liner, leaving you with a safely lined pipe-within-a-pipe that will serve you for years to come. 

No new pipes. No digging. No property damage. No problems. That’s innovation.
