CIPP / Pipe Lining
CIPP, or cured-in-place pipe lining, is a trenchless repair that pulls a resin-soaked liner into a damaged sewer pipe and hardens it into a new pipe inside the old one.
CIPP stands for cured-in-place pipe, a trenchless way to rebuild a failing sewer line without digging it up. A flexible felt or fiberglass liner is saturated with resin, pulled or inverted into the old pipe through an existing access point, and then cured, with hot water, steam, or UV light, until it sets hard. The result is a smooth, jointless pipe formed inside the old one, sealing cracks and stopping the gaps where roots got in.
Homeowners reach for lining when a camera inspection shows a cracked, corroded, or root-infiltrated lateral that is still structurally whole enough to host a liner. The appeal is that the yard, driveway, patio, or landscaping stays mostly intact, since the crew works through one or two small access pits instead of trenching the whole run. The new liner also slightly narrows the pipe’s inside diameter, but the smoother surface usually keeps flow capacity about the same.
Lining is not right for every case. A pipe that has collapsed, badly sagged, or lost too much of its wall needs pipe bursting or a traditional dig-and-replace instead. A plumber decides between lining and replacement based on what the camera shows.

- Drain Field / Leach Field : A drain field, or leach field, is the network of buried perforated pipes and gravel that releases treated septic effluent into the soil for final filtering.
- Septic Tank : A septic tank is the buried watertight container that holds household wastewater long enough for solids to settle out before the liquid flows to the drain field.
- Backwater Valve : A backwater valve is a one-way gate installed in a sewer line that lets wastewater flow out but slams shut to stop sewage from flooding back into the house.
- Effluent : Effluent is the clarified liquid wastewater that flows out of a septic tank to the drain field after the solids have settled and floated out of it.
