Pipe Relining and Other Types of Sewer Line Repair Technology

Talk to anyone of your friends about their ideal property and they are likely to tell you that a detached home with a sprawling lawn and large oak trees would be the perfect retreat at the end of the day. Lovely are trees and plants but as a homeowner, you should be aware that underneath is a potentially expensive repair waiting to happen – root intrusion on pipes.

The limited options of homeowners a few decades ago saw them spending a fortune for replacing pipes at the event of root intrusion. When this happens, apart from the very expensive amount needed to complete the project, there are also concerns of excessive digging, property disruption and long days of work. As a whole, pipe replacement does not just come with a hefty price but with a lot of hassle too.

The good news for homeowners, there are many more options for pipe repair that they can opt for. Aside from pipe replacement, there is pipe relining and other types of sewer line repair technology that can be chosen from.

About Sewer Line Repair Technology

Sewer Line Repair Technology is the collective term for different methods, equipment and material that make it possible for technicians to repair, lay and maintain pipes with minimal digging while some technologies do not require any digging at all. There different types of pipe lining systems that can be used for different types of plumbing problems.

Types of Sewer Line Repair Technology

Cured-In-Place Pipe

The CIPP is a type of technology that quickly and efficiently repair pipe sections that are still in relatively good condition but need added strength. In this process, the pipe is relined using seamless PVC liner to seal the cracks and void of the pipe. The old pipe would first be cleaned using a hydro jet to remove any clogs and to clear of root intrusions. The liner will then be sealed using high pressure steam run through the liner. This process could not be used for pipes that have weakened or are in unstable condition.

Pipe Bursting

Pipe bursting is used to replace the existing sewer line. The process involves a small opening made at each end of the pipe that will be replaced. The moment the openings are made into the pipe, a thick cable is inserted through on end to end and a spear-shaped tool for bursting is attached. The HDPE section of the pipe is attached to the other end and as the bursting head is pumped through, it “bursts” the old pipe is replaced with a new pipe. This process is advisable for pipes in bad condition that they can’t be relined using the CIPP process.

Pull-in-Place Lining

This process uses fibreglass and resin to line the existing pipe which has cracks or has partial gaps. There are two small holes that should be dug for the process- one before and one after the area that will be fixed. The liner is pulled in place using a wench and then it is cured with heat or steam.

Inversion Lining

The inverted lining method is used to seal a pipe that is still in solid condition but could still have a few cracks or gaps. The process involves digging a small hole near the area where the inversion liner must be placed. The liner is usually made of felt tube and resin. It results in a smooth and joint less lateral which makes it strong and durable.

Moling

The process of moling means laying down new pipes to keep from damaging the landscape. This is done with the help of a special machine driven pneumatically through the soil and into the proposed path of the pipe. The mole is a steel cylinder that is about 60 cm long and is 6 cm in diameter. A hole is created by the mole and the pipe can be placed simply.
