How CIPP Is Different From Directional Drilling?

Introduction

Both CIPP and Directional Drilling are types of trenchless plumbing. Advances in plumbing technology have created ways to install and do major repair work to sewer lines without using traditional methods such as backhoe trench digging. The costs homeowners and businesses incur can amount to thousands of dollars for the replacement or restoration of the landscape and hardscape. That is why CIPP and directional drilling have become two of the most popular and cost-effective ways of dealing with broken sewer lines.

CIPP

CIPP is an acronym for Cured In Place Pipe. This approach to Sewer Line Repair uses a corrosive resistant resin that is applied to the inside of the existing sewer line. Before applying the resin to the interior walls of the line, the plumber clears out all debris from inside the pipe and follows up by cleaning the inside of the pipe. A video inspection is then made of the pipe for the record to demonstrate the inside of the pipe is clean prior to applying the resin. The resin is then sprayed to create a single, continuous, jointless seal that can last as long as 50 years. Once the resin has completely dried, a second inspection is conducted to make sure there are no holes, pits, or anything that would cause the new line to fail.

Directional Drilling

Directional drilling is a Trenchless Method that involves preparing the insertion of an underground sewer line in several steps. First, the area where the line is to be placed is inspected for any potential obstructions and other problems that can interfere with the safe drilling. A hole is drilled on an angle to clear the way for the insertion of the sewer pipe. Several holes, called pilot holes, are drilled to track the progress of the drilling. As the drilling continues a reamer is inserted to create a hole about 1/4th larger than the size of the pipe to be inserted. The new line is then pulled through the hole and the connections are finalized.

When To Use

CIPP is used when the goal is to repair or retain the existing sewer line. Directional drilling is used to replace a sewer line.

CIPP does not involve any drilling, but instead the installation is done through existing sewer lines and connections. Directional drilling requires the pilot holes to be made, but apart from those your hardscape and landscape remain intact.

CIPP is the better choice when the line to be repaired runs under a sidewalk your walkway because it will not affect the terrain above it.

Directional drilling is the choice when a new line needs to be installed. Depending on the layout, a new line can be installed in close proximity to an existing line.

Both are environmentally friendly

Both will save you considerable time and money compared to the more traditional alternatives

Only an experienced plumber can make the best recommendation for your particular situation. But it is important for you to know the basics and the differences between the two trenchless methods so you can know what options are available to you and the cost saving that come with the different methods.
