# SewerRelining.ca

> Sewer relining (CIPP) explained from the liner up — resins, cures, reinstatement, prep, lifespan, standards, and when a line cannot be lined. SewerRelining.ca is part of the HAUSE Sewer network — an independent Canadian information and service-request network (not a contractor). Contact: sewers@hause.ca, 403-679-3100.

Sewer relining, or cured-in-place pipe (CIPP) lining, renews a buried sewer from the inside. A flexible tube of felt or glass fibre is saturated with resin, inverted or pulled into the cleaned host pipe, pressed against its wall and hardened with hot water, steam, UV light or time. The result is a jointless pipe inside the old one, designed for the loads it must carry.

### Engineering
- [Liner thickness and ASTM F1216: how a liner wall is designed](https://sewerrelining.ca/guides/liner-thickness-and-astm-f1216/): How CIPP liner thickness is designed under ASTM F1216: partially vs fully deteriorated pipe, groundwater, ovality, soil and traffic loads, and testing.

### Materials
- [CIPP liner tubes: felt, glass fibre, membranes and bladders](https://sewerrelining.ca/guides/cipp-liner-tubes/): The fabric tube inside a sewer liner: felt and glass-fibre types, coatings and membranes, preliners, calibration hoses and bladders, and what each changes.
- [CIPP resins: epoxy, polyester, vinyl ester and silicate](https://sewerrelining.ca/guides/cipp-resins/): The resins that harden a sewer liner: unsaturated polyester, vinyl ester, epoxy and silicate systems, styrene, UV resins, and what to ask about a resin.

### Performance
- [CIPP liner failures: wrinkles, lifts, delamination and soft resin](https://sewerrelining.ca/guides/cipp-liner-failures/): The defects a relined sewer can have: wrinkles and fins, lifts, delamination, uncured resin, dry spots, unsealed ends and bad cuts, with causes and fixes.
- [How long does sewer relining last?](https://sewerrelining.ca/guides/how-long-does-sewer-relining-last/): How long a CIPP sewer liner lasts: the 50-year design life, the 1971 Hackney liner, creep and long-term properties, what shortens a liner’s life, and warranties.

### Process
- [CIPP curing methods: hot water, steam, UV light and ambient](https://sewerrelining.ca/guides/cipp-curing-methods/): How a sewer liner is cured: circulated hot water, steam, UV lamp trains in glass-fibre liners, and ambient cure, with the records each should leave.
- [Cleaning and descaling a sewer before it is lined](https://sewerrelining.ca/guides/cleaning-and-descaling-before-lining/): How a sewer is prepared for a CIPP liner: jetting, root cutting, cast iron descaling, grinding protruding taps, flow control and the post-cleaning video.
- [How sewer relining works, stage by stage](https://sewerrelining.ca/guides/how-sewer-relining-works/): How sewer relining works from the first camera run to the final video: measuring, flow control, cleaning, wet-out, inversion, cure, reinstatement and records.
- [Inversion vs pull-in-place: how a liner gets into the pipe](https://sewerrelining.ca/guides/inversion-vs-pull-in-place/): The two ways a CIPP liner is installed: inversion by water or air pressure (ASTM F1216) and pull-in-place with a calibration hose (F1743, F2019), compared.
- [Wet-out and calibration: how a liner tube is saturated with resin](https://sewerrelining.ca/guides/wet-out-and-calibration/): How a CIPP liner tube is wet out: resin volume, vacuum impregnation, calibration rollers, cold storage, plant or site wet-out, and the defects it causes.

### Safety
- [CIPP lining smell and styrene: what to know and what to do](https://sewerrelining.ca/guides/cipp-lining-smell-and-styrene/): Why sewer relining smells like plastic or glue, what styrene is, what Toronto and Calgary tell residents, what NIOSH found for workers, and how to keep odour out.
