Pipe Lining and Pipe Bursting: A Helpful Comparison of Top Trenchless Methods

When underground pipes become damaged, homeowners often worry about the cost and disruption of traditional repairs. Thankfully, trenchless technology offers less invasive options. Two common and widely used techniques are pipe bursting and trenchless pipe lining in Chesterfield, VA. USA Pipe Repair shares a simple comparison to help you understand how each method works and which may be best for your situation.

How Pipe Lining Works

Pipe lining, also known as cured-in-place pipe (CIPP) lining, involves inserting a flexible tube coated with resin into the damaged pipe. Once in place, the resin-impregnated liner is inflated and cured, creating a new pipe within the old one. CIPP pipe lining is typically used for repairing pipes with minor to moderate damage, such as cracks, leaks, or minor corrosion.

One major advantage of cast iron pipe lining is its ability to restore the system’s integrity without the need to fully replace the existing infrastructure. The new liner creates a smooth, jointless surface that is more resistant to corrosion, root intrusion, and other common causes of pipe failure. 

It is, however, generally not suitable for pipes that have collapsed or suffered severe structural damage. This is because the liner needs a structurally sound and intact existing pipe to adhere to.

A Look at Pipe Bursting

Pipe bursting is a trenchless technique often used when the original pipe is too damaged for sewer pipe lining. It involves breaking apart the old pipe using a bursting head, while simultaneously pulling a new pipe into its place. 

Aside from its effectiveness in fully replacing outdated or compromised pipes in a speedy manner, pipe bursting has the added advantage of being able to slightly increase the diameter of the replaced pipe, thus improving flow and capacity. Typically, the new pipe is made of high-density polyethylene (HDPE) or another material with similar strength and durability.

Not Sure Which Trenchless Method is Right for You?

Thankfully, you don’t have to make that decision on your own. Your trenchless contractor will evaluate the unique needs of your project and recommend the best method. As discussed earlier, a primary factor in determining which method to use is the type of damage or issue you are facing with your current pipeline. Still, other factors such as soil conditions, location of utilities, and budget can also play a role.
