How Trenchless Pipe Lining Is Performed

Trenchless pipe lining is a process wherein a “new pipe” is created within a damaged pipe to restore functionality. Although this pipe rehabilitation method has been around for decades, many are still largely unfamiliar with how it works. If you’re a property owner or facility manager faced with sewer pipe problems, it might be beneficial to consider trenchless pipe lining in Sioux Falls, SD.

When pipe lining companies like yours truly are called upon for a job, these steps are typically what’s carried out.

Initial Pipe Inspection

Our team will not start off any sewer pipe lining project without inspecting the affected pipe first. We do so with the help of a camera that’s specially designed to fit into sewer pipes while providing clear, real time footage. We conduct a pipe inspection to determine if the process is in fact suitable for the condition of the pipe and the nature or extent of the problem.

Cleaning the Pipe

Once all the relevant information has been retrieved, the pipe is cleaned by directing a high-pressurized jet of water through the pipe by the hydro jetting technique. This removes all the dirt that may be clogging the pipes. When a tree root blocks a pipe, a rotating blade is inserted inside the pipe to cut the roots. The cleaning process ensures the CIPP pipe lining is successful and the liner adheres properly.

Taking Measurements

The pipe is measured to determine the amount of liner required for the process. This is an important step, with very little room for error, as it can directly affect the success of the procedure.

Pipelining

The actual trenchless pipelining process makes use of a flexible felt liner tube saturated with epoxy resin. The resin used is carefully measured and mixed according to the amount of liner required, which was determined during the measurement of the pipe. The mixture is then poured into the tube liner and turned, flipped and rolled a number of times to ensure proper impregnation of the liner with resin. Using an advanced inverter drum, the liner is inverted inside out by blowing air pressure into it while it is being inserted into the affected pie.

The inverted liner has resin on the outside, bonding and sealing with the existing host pipe. It adheres to the walls of the existing pipe in around 30 minutes to form an airtight seal with the existing pipe.

With those few simple steps, the work in your yard will be completed leaving your pipes in top-notch condition. The SD Lining Solutions team offers various trenchless solutions, including cast iron pipe lining.
