How Trenchless Sewer Pipelining Works

Fortunately, there are several different types of trenchless sewer pipelining that can be used. These methods include spray lining, slip lining, and brush coating. The best trenchless pipelining for your home or business depends on several factors, including cost, the size of your pipes, and your specific needs.


Several factors will determine the cost of a trenchless sewer pipeline, whether you are looking for a minor repair or an entire sewer line replacement. These factors include the depth of the sewer line, the line’s size, and the pipe’s condition.

The cost of trenchless sewer pipelining will vary greatly depending on the situation. For example, the price of pipe lining is generally higher than traditional pipe bursting. But it’s also important to understand that trenchless sewer pipelining costs as much as half of what it would cost to replace the pipe using traditional methods.

Trenchless techniques are more expensive upfront but save you money in the long run. They also require less maintenance and can save you time and energy. The cost of trenchless pipe lining varies by pipe size but averages around $150 per foot.

Slip lining

Using the slip-lining method to repair an existing sewer line is an effective and economical way to fix pipes. Typically used for minor problems, such as leaks, slip lining can provide a sturdy pipeline without replacing the entire system.

The slip-lining method involves installing a PE100 liner pipe into the existing pipe. The resin-impregnated liner is pulled into the pipe and cured in place. The new line will have a smaller inside diameter but a thicker wall and a larger outside diameter.

Slip lining can be segmental or continuous. Generally, continuous slip lining uses one straight pipe. However, it can also be segmental, utilizing individual pipe pieces.

This method is particularly effective at restoring hydraulics in a system. However, it is less flexible than the cured-in-place method. It can be a problem if the pipe breaks during installation.

Spray lining

Whether you have an old cast iron sewer line or a small branch line, spray lining can effectively repair your pipes. It is also a great way to prevent corrosion in your pipes.

There are several different spray-lining techniques. You may have heard of cured-in-place pipe lining (CIPP) or structural pipe lining. You can fix pipelines without digging by employing one of these techniques.

There are other trenchless sewers pipelining methods, including slip-lining and pipe bursting. They involve pulling a smaller diameter pipe into the existing pipe. It can hurt your pipes’ flow capacity.

Pipe bursting involves breaking up your pipes underground. The bursting head is slightly bigger than the pipe. So it pulls through the old pipe. The new line can be the same diameter or the next larger diameter.

Brush coating

With brush coating, you can upgrade an outdated sewer line or replace an existing one without digging up your backyard. It’s also a relatively inexpensive option; you can expect it to last for several decades.

Brush coating is a method that involves using a set of brushes to push an epoxy resin into your pipe. The process is relatively easy and can be completed in less than a week.

The process works best on pipes with cracks less than two inches wide. It’s also a great way to protect your sewer from corrosion.

There are many types of trenchless technology, and they all have advantages. So it’s essential to know which one you’re going to use.

Cure-in-place lining

CIPP, cured-in-place pipe lining, is a trenchless technique to restore or repair sewer and water pipes. It is an alternative to digging and is better for homeowners. However, it does require special skills and knowledge to perform.

The lining process starts with a wet-out stage, where the pipe is cleaned out, and a new liner is installed. A CIPP liner is a fiber-reinforced fabric with a polymer film to protect it. The liner is then inverted into the pipe with air pressure.

Other plastic pipe installation techniques take longer than installing a CIPP liner.

Additionally, it is more economical. Installations with CIPP typically last 50 years. It is also suitable for short runs of pipes.

There are two types of CIPP pipe relining. Typically, they are made from woven fabric, but other materials are available.
