CIPP Sewer Lining

CIPP stands for cured-in-place pipe — a category of trenchless pipe rehabilitation covered by ASTM standards F1216 (inversion installation) and F1743 (pulled-in-place installation). The finished liner is a fully structural pipe, meaning it can stand on its own even if the surrounding host pipe deteriorates further. That's an important distinction: CIPP isn't a coating or a patch. It's a real pipe installed inside another pipe.

The installation is straightforward in concept: a flexible tube (usually needle-punched polyester or fiberglass) is saturated with a two-part thermoset resin, inserted through an existing access point, inflated so it presses against the host pipe wall, and cured until the resin hardens. What comes out the other side is a seamless, jointless, chemically-resistant pipe.

We match the resin to the job. For most residential sewer laterals in Columbia and the Midlands, we default to a two-part epoxy — it's forgiving during installation, produces a robust cured liner, and has an excellent long-term track record on the pipe materials we typically see (cast iron, clay, Orangeburg). For more demanding environments — industrial waste streams, higher temperatures, aggressive chemistry — we use vinyl-ester resin, which is more chemically resistant but requires tighter installation control.

Cure method depends on liner size, resin type, and site conditions:

Ambient and steam cure cover almost all residential and light-commercial CIPP work in Columbia, SC.

We're happy to discuss the specific system and standards behind any quote we give you — good CIPP work has nothing to hide.

A properly installed CIPP liner is smooth, seamless, and slightly lighter in color than the original pipe. On camera it presents as one continuous surface with no visible joints, no ridges, and no folds. Water flows over it hydraulically better than the original pipe — often improving drainage in older lines. We camera every lined pipe on completion and share the footage with you.

CIPP is the right answer when a pipe is structurally deteriorated but still holds its shape. Cracks, longitudinal splits, root intrusion, corrosion, and channeling are all textbook CIPP cases. Full collapses, severe belly-shaped sags, and pipes that have completely lost their round shape usually require a different approach — either pipe bursting or targeted excavation. We tell you which category your pipe is in after a camera inspection, and we don't pretend CIPP fits a job it doesn't.

• Ambient cure — the liner is left inflated at room temperature for several hours while the resin hardens on its own. Slowest but simplest.
• Steam cure — heated air (typically ~180°F) is pushed through the inflated liner, accelerating the cure to under an hour for small residential runs. This is our default for most jobs.
• Hot-water cure — recirculating hot water through the liner; common for larger municipal work.
• UV cure — a UV light train is pulled through the liner; very fast but requires specialized equipment. Used mostly on municipal mainlines.
• ASTM F1216 and ASTM F1743 — the primary installation standards for inversion and pulled-in-place liners.
• ASTM D5813 — the material standard for CIPP resins and liners.
• Manufacturer certification for the specific liner system being installed. Legitimate CIPP systems require installer certification.
• Trenchless Pipe Lining (overview) — the broader category CIPP belongs to.
• Sewer Camera Inspection — the diagnostic that determines whether CIPP fits your pipe.
• Hydro Jetting — often used to prep a line before CIPP installation.

Every CIPP job we do starts with a camera inspection so you know exactly what's in your line. Then we quote in writing before we touch anything.
