Trenchless Sewer & Drain Pipe Repair

Sewer & Drain

NuFlow has been helping property owners and managers solve sewer and drain problems for over 20 years.

There are several red flags that might mean more problems are starting. Contact your local NuFlow Certified Contractor to help you avoid costly pipe failures down the road!

  • Repeat sewer stoppages
  • Unpleasant odors
  • Slow flushing toilets
  • Slow drains in showers and sinks
  • Gurgling drains
  • Persistent insect or rodent issues

These problems are often caused by old sewer and drain pipes suffering from:

Most jobs require only one or two days to complete!

Utilizing cutting-edge technology, trenchless sewer repair has never been easier. With trenchless sewer repair, the need for digging trenches is eliminated, all that is needed is an access point to allow for the saturated liner to be slid into place.

The flexible liner and liquid epoxy cures in place inside the old pipe, creating a rigid “pipe within a pipe.”

Trenchless sewer line repair also cuts restorative costs, creates little material waste and extends the life of your drain lines. If you are struggling with a sewer emergency, time is of the essence, and NuFlow’s trenchless sewer repair can help you keep your mind at ease.

What kind of problems does NuFlow structural lining technologies address?

Group 8370 (2)

Aging and Corroded Sewer Lines

Most facilities/structures built prior to the early 1970s have sewer lines composed of primarily cast iron and clay. These lines are subject to cracking and rusting out at the bottom, which leads to root intrusion at the joints and cracks.

Root intrusion into sewer pipe systems is reported to cause 50% of all sewer blockages. Interference of trees into sewer systems is likely to occur in older systems and in cracked pipes. Factors that contribute to damage include older pipes with joints, shallow pipes, small-dimension pipes and fast-growing tree species. Cost associated with caring for root intrusion in the past has been expensive and laborious and unfortunately, is rarely a long-term fix.

NuFlow structural lining technologies protect against further intrusion in joints and cracks. Because of the nature of root intrusion, it is best to reinforce and protect pipes before major intrusions have taken place.

Ground Movement Affecting Pipe Integrity

Major seismic activity can cause breaks in sewer pipe lines, but more frequently, minor seismic activity causes cracking and structural damage at the joints.

The seamless, “jointless” nature of the NuFlow pipe lining method means not only is the existing problem solved, but the new, seamless pipe will avert future problems as well.

Calcification in Sewer Lines

Over time, sewer lines will calcify as calcium deposits from the water build up over time and create a coating that clogs up household pipes and drain lines. This is especially true for buildings with hard water due to its high levels of calcium.

NuFlow epoxy lining makes it impossible for calcium deposits to adhere to the interior walls of the new epoxy barrier pipe, preventing future calcification.

Where Can Pipe Lining Be Used? Just about Anywhere!

Corrosion and pinhole leaks are the main culprits in thousands of plumbing issues every year, from single family homes to multi-story commercial buildings. Older buildings are more likely to have copper water lines and drains made of cast iron, both subject to corrosion over time.

Trenchless sewer and drain pipe repair is appropriate for all types of buildings including:

  • Single family homes and multi-tenant buildings
  • High rise condo and apartments
  • Commercial properties
  • Hospitals
  • Historic buildings
  • Schools
  • Any building or structure with sewer drain, waste and vent systems

Trenchless sewer pipe repair is ideal for crowded urban areas that have lots of pedestrians and underground utilities. This technology allows underground utilities to be repaired safely while minimizing inconvenience and personal risk.

Once pipes are repaired you will notice several benefits:

  • Improved flow rate
  • Structurally sound pipes
  • No groundwater contamination
  • No tree root invasion
