CIPP Lining

Tip: Vacuuming Out Air Pockets When Wetting Out

Vacuuming a CIPP lateral liner eliminates entrained air from a liner tube. Lack of vacuum impregnation will leave dry spots that allow roots to penetrate over time where no resin is present. It also meets the ASTM standards for CIPP lining. For more information contact Pipe Lining Supply at +1-888-354-6464 or email us at info@pipeliningsupply.com.

Tip: Expense and Revenue

When we’re new to technology, we tend to take every job that comes along. More than one has failed to tackle a job that everyone else has turned down as too difficult or impossible to complete. If the expenses to get it down are more than the revenue, you are ahead by turning down the […]

Tip: Pipe Diameter

Pipe diameters on laterals usually make a transition in sizes somewhere between the building and the sewer main. For CIPP projects, you can select one of two methods from a variety of liners. You can buy pre-made transition bags sewed to transition from one diameter to another in various lengths, or you can buy liner […]

Pull-In-Place CIPP Liner VS Inversion CIPP Liner

“I’m confused. I was shopping for a lining system to install liners at the WWETT show but left not buying anything. One vendor told me inversion was the only way to install liner as it would travel farther than pull-in-place, and another vendor told me that pull-in-place liner was better because it didn’t squeeze out […]

Special Resin For PVC Pipe vs. Other Pipe

“My supplier told me I had to use a special epoxy resin to line PVC pipe. Is there different resin formulations for different types of host pipe material or is this guy blowing smoke?” Either your supplier is mistaken in their understanding or they are indeed blowing smoke but there is no resin formulations that […]

Winning & Losing in the Market Place

“I’m in an area that mostly digs up and replaces the pipe. When I present CIPP lateral lining as a possible alternative, most of my customers would prefer to dig up the old pipe and put a new one in. Do you have any tips that would help be more successful in presenting lining over […]
