Slab Leak Epoxy Repair - No Jackhammer or Reroute | Nu Flow


What is a slab leak? A slab leak is a pinhole leak that has developed in a copper pipe below the concrete floor of your home. There are several ways to determine if you have a slab leak:

  • High water bill
  • Water sound, but nothing is running
  • Wet planters near the house
  • Warm spots on the floor
  • Wet baseboards and flooring

The Nu Flow solution: Avoid unnecessary damage to your home with Nu Flow's single line restoration! No need to jackhammer or reroute a leaking line, we will repair the active leak with our epoxy coating technology. Not only will our epoxy repair save you time and money, it will also eliminate any future leaks from this problematic line. Epoxy repair is typically 50%+ cheaper than other alternatives!

FREE inspection: At no cost to you, Nu Flow will perform a visual inspection and a pressure test of your home. Once we have confirmed that a slab leak is present, we can offer you our leak detection service in order to pinpoint the active leak. The goal of our leak detection service is to locate both ends of the leaking line so that our epoxy repair can be made.

How It Works



To properly repair your active leak we must isolate the line from the plumbing system. This requires two small openings… point A (where the pipe enters the ground) and point B (where the pipe exits the ground).


A pressure test is performed to determine the size of the leak and the number of coats that may be needed to seal the leak.


Using dehumidified compressed air we purge out any remaining water and properly dry the pipes. In order ensure good adhesion of the epoxy to the pipe, a safe abrading agent is then blown through the pipe to eliminate any corrosion or build up. The pipe is now clean and ready for epoxy restoration.

Epoxy Repair

A calculated measurement of epoxy is then blown through the pipe and air pressure is adjusted to ensure a successful repair of the leak. Following the coating application, conditioned and controlled air flows through the pipes to facilitate epoxy curing.


A final pressure test is performed to confirm that the leak has been repaired. The pipe is then reconnected to the system, and water is turned on. No more leaks!

The Benefits

Safe and Durable:
Nu Flow's epoxy is Truesdail Laboratories certified safe to NSF/ANSI Standard 61. Nu Flow's epoxy was developed and patented by the U.S. Navy and has been successfully applied by Nu Flow technicians since the mid-1980s for the U.S. government and in domestic, commercial, industrial, and other applications. Testing engineers estimate the life expectancy of the epoxy is roughly 100 years.

Cost Effective:
Single line epoxy coating is as much as 50% less expensive than traditional re-route costs. No need to jackhammer your floors or tear apart your walls and ceilings! Epoxy Coating is a non-invasive process, so there is no major destruction to your home!

Minimal Downtime / Disruption:
The single line process takes a fraction of the time compared to traditional re-route methods. We eliminate the additional time of demolition, re-construction, painting and cleaning. With epoxy repair the pipe is repaired and reconnected to the system within 24 hours.

Our epoxy coating process was developed and patented by the U.S. Navy and has been successfully installed by Nu Flow technicians nationwide for nearly 30 years.
