Pull-in-Place
Pull-in-Place (PIP) pipe lining is an effective procedure that restores corroded or eroded drain, waste, and vent piping systems without the costly expense and disruption of pipe replacement.
Pipe replacement in aging facilities, the traditional alternative to pipe lining, comes with a host of concerns and issues that must be dealt with, some of which can render such work highly prohibitive.

Pipe lining provides an efficient, effective alternative with many benefits, which include:
- Significant savings over other methods
- Increases useful life of piping system
- Very little disruption, if any
- Preservation of building structure and surrounding landscape or hardscape
- Eco-friendly "Green" practices
- Protective liner prevents corrosion and leaching of harmful elements into the soil or building structure
- A "No Dig" trenchless technology
- Increases flow capacity
Pull-in-Place pipe lining works under a wide range of circumstances.
- Commercial, Industrial, and Government
- Hospitals/Medical Facilities
- Underground Main Lines
- Sanitary Drainage/Sewer Pipes Only
- Vertical Stacks - Kitchen, Laundry, & Vents
- Horizontal Underground Pipes - Under Slab
- Branch Lines as Small as 2"
- Lateral Lines - From City Main to Building
- Has two access points (upstream and downstream)
- Ability to use one access and push liner into place
- Installation of the liner is a controlled and placed type of installation
- Multiply 45° and 90° bends can be accomplished in one pull
- 2" to 12" in Diameter Pipes
These are reasons why pipe relining is a better solution than pipe replacement.
THE PROCESS
1. Initial inspection of the pipe will be performed by using a Close Circuit TV (CCTV) camera. During the inspection we will measure the length and diameter of pipe as well as locate any problems (corrosion, tree roots, cracks, blockages, off sets).
2. Thoroughly clean the interior surface of the pipe by using proprietary mechanical tools to remove corrosion, tree roots, and blockages.
3. A second camera inspection is completed to confirm the condition of the pipe, verify that it is clean, and to remove any debris.
4. A felt liner is measured and cut to the dimensions of the pipe that is being lined, such as length and diameter. The felt liner is saturated with a two-part epoxy and inserted into the upstream access point.
5. An inflatable bladder is inflated (that was previously placed inside the felt liner) inside of the epoxy saturated liner. By inflating the bladder this allows the felt bladder to take shape of the inside of the pipe while it cures.
6. After the epoxy cured and the felt liner is hardened the bladder is extracted and leaving a pipe inside a pipe.
7. A third camera inspection is completed to insure the entire pipe was lined.
8. Any branch lines would either be gapped or reinstated.
9. The end process is a fitted, smooth, and corrosion - resistant new pipe wall.
