What is Trenchless Sewer Repair?

Trenchless sewer repair is a cost-effective, time-saving, and lasting solution to replace broken underground sewer pipes.

Trenchless technology only involves finding two access points. For example, we can dig one 4ft by 4ft pit for one and remove a toilet for the other. There are two different options for how we can replace your pipes below. But before we go into that, see how trenchless technology is better than conventional methods, and how we at New Flow Plumbing have mastered the craft.

Is Trenchless Sewer Repair Better?

Conventional sewer line repair can involve tearing up your yard, ripping apart floors and walls inside your home, and can take days to complete. When that’s done, you’re left with the cost of replacing and repairing all the damage to your property.

Trenchless technology is fast, only taking a few hours once the work begins. We can keep your home looking good while the work is being completed.
We perform a CCTV inspection of your pipes and assess which method is the most effective. A camera is fed into cleanouts, a vent stack opening, or by removing a toilet. (We will put everything back together once we’re done.)

Trenchless Sewer Pipe Lining

Also called structural pipe lining, or cured-in-place lining (CIPP), involves a special, epoxy-impregnated liner to create a new pipe directly inside your old one. CIPP is designed to last up to 50 years!

Note: The pipe’s diameter does become slightly smaller but it increases your new pipes flow capacity.

Pipe Bursting

If a pipe is too damaged to be lined, losing its structural integrity, we will use pipe bursting instead. It has some limitations that make it more ideal for straight runs of pipe (the HDPE material would have trouble navigating bends in your sewer). HDPE is designed to last up to 100 years!
  1. Again, we perform a CCTV inspection and see how the pipe is holding up. We make sure we are not able to use pipe lining.
  1. Next, we find our two access points, one on each end of the pipe, typically in your yard.
  1. The brand new HDPE (high-density polyethylene) pipe is attached to a winch with a cone-shaped bursting head and pulled through the damaged pipe. The damaged pipe is broken apart as the new pipe takes its place.
  1. We perform another CCTV inspection to ensure everything is completed and then fill in any pits or reinstall any fixtures we removed.

This is an environmentally-friendly process that involves no chemicals.

Can All Pipes Be Repaired Using Trenchless Technology?

This method can be used for cracked, corroded, leaky, or misaligned pipes. If they’re under homes, commercial buildings, or landscaping that you do not want to be torn up, trenchless technology can take care of it! We can also fix any vertical stacks in multi-story buildings and lateral lines that connect to a city sewer or septic tank.

Note: Sometimes a sewer pipe is so badly damaged that no trenchless repair method is usable.

When it’s impossible to use a trenchless repair, we use conventional sewer replacement methods

How Much Does Trenchless Sewer Repair Cost?

Trenchless sewer repair typically saves property owners between 30-40% of their entire project cost.

Trenchless sewer repair quotes may be anywhere from 30-50% more than the conventional sewer repair methods, but it is still a cost-effective solution because we do not destroy your property to get to the pipe. This means we save you thousands of dollars on restoration and clean up costs.

Whatever solution is needed, we at New Flow Plumbing can find your problem and fix it in no time!
