What is Pipe Lining?

Pipe relining, commonly referred to by its other names such as epoxy pipe lining or CIPP lining (cured-in-place pipe), is a non-invasive sewer repair procedure in which a new pipe is constructed directly within existing ones without cutting or trenching; providing fast, simple, and cost effective repairs for pipes. Denver Sewer And Water’s team of highly trained technicians is committed to offering customers in Denver top-quality Trenchless sewer line repair in Denver at an affordable cost and without stress or strain. We understand the hassle associated with such work and strive to make this process as straightforward and stress-free as possible for them.

Before inserting a pipe liner, all pipes are first examined using a sewer camera, and cleaned using hydro jetting. Next, a brand new liner for your existing one is placed and then inflated, creating an all-new pipe without leaks from pinholes that is designed to last a long time.


  • Cost effective
  • Faster than traditional pipe replacement
  • Long lasting pipe lining solution
  • Environmentally friendly


  • Hard to remove
  • Must be installed correctly

After carefully inspecting your home’s damaged sewer pipes, it’s time to begin thinking about repairs to restore them. Uncertain about what lies ahead – expensive digging, replacing of old systems with new, potential damage to property etc – trenchless technology offers homeowners an affordable yet effective alternative that’s both cost-efficient and time efficient.

Trenchless pipe lining is often employed to repair damaged sewer pipes which are manageable and simple to repair. Trained professionals who employ trenchless pipe lining apply epoxy Permaliner inside damaged pipes before curing the liner using air pressure, creating what is commonly referred to as “cured-in-place pipe,” or CIPP.

Plumbers can use these lining solutions for repairs to manhole-to-manhole pipeline lines, lateral linings and even targeted repairs on segmented pipes, known as sectional point repair. Moreover, their efficiency reduces lengthy labor hours saving homeowners both time and money in labor costs.

Types of Sewer Pipe Lining Advice

Internal Pipe Coating

It is commonly employed both in homes and commercial environments due to not destroying flooring or walls in order to access pipes that need repair. Once draining has taken place, an epoxy coating will be applied directly on to those tubes which require repairs.

Following treatment, all cracks, leaks or leaks will be completely repaired, making the pipe as good as new and increasing water flow through it! Furthermore, pipes may become resistant to internal corrosion while decreasing formation of deposits on their interior walls.

Pipe Bursting

Although this option may create some interruptions due to drilling of holes, don’t fret as pipe bursting is only required in cases of severely damaged sewer pipes that need replacing immediately.

At the core of each pipe lies a “bursting head.” When moved across an existing line, this “bursting head” splits it and pulls a new one behind it, completely replacing the old system.

Cured-in Place Piping (CIPP)

Cured-In-Place Piping (CIPP) refers to pipe systems fabricated with cured material for installation into existing infrastructure and used without modification during their service lives.

Internal Pipe Coating is similar to Pipe Bursting; however, unlike its name implies it does not repair the outside of a pipe; rather it repairs damage on its interior surface. Therefore this method is ideal for lines experiencing minor damages caused by common plumbing issues.

After draining and drying the pipes, a liner is secured in place by steam that is hot to ensure its adhesion to cracks in the pipe that require filling – without disrupting your house or area in any way. The benefit is no disruption from this method!

Pull-in Place (PIP)

Pull-In Place is another method available to repair any damages that CIPP cannot remedy. As its name implies, the pull-In Place system involves placing and sealing fiberglass or resin liners using steam or heat for installation and fixation – similar to how CIPP works but different from its techniques used.
