Drain relining outside London.

Cured-in-place pipe (CIPP) drain relining is the specialist no-dig repair for cracked, fractured, root-invaded, or partially collapsed drains. A resin-impregnated felt or fibreglass liner is inverted or winched into the host pipe, inflated, and cured to form a new structural pipe inside the old one. The result is a smooth-bore, jointless, 50-year-design-life repair with no excavation, no reinstatement of paths or driveways, and no drainage shutdown beyond a few hours. It is the obvious answer where digging is impractical, but it requires kit, training, and resin chemistry that most local drainage firms do not carry.

We run UV-cured and steam-cured liner systems with WRc-approved resin (typically Brawoliner, IMPREG, or Per Aarsleff), capable of installations up to 100m in a single shot on 100mm to 225mm host pipes, plus patch-liner repairs for spot fractures down to 50mm runs. Every job is preceded by a jetting clean and a CCTV pre-install survey, lined to BS EN 13566, with a post-install CCTV pass as the as-built record. Kit, resin, UV-train or steam calibration, and a qualified lining engineer are all in the day rate.

How an out-of-area CIPP install runs

Eight stages, every one of them documented on the CCTV pre and post-install record.

1. 1
   Free phone scope-out
   A 10 to 15 minute call to understand the symptoms, the property age, what surveys have already been done, and whether CIPP is even the right answer for the run in question.
2. 2
   CCTV pre-install survey
   A day on site with high-pressure jetting, push-rod and tracked CCTV, distance and gradient logging, and a written report identifying the host-pipe diameter, defect locations, and liner specification.
3. 3
   Written quote with mileage breakdown
   Liner type and length, resin volume, day rate per engineer, mileage at HMRC AMAP £0.45 per mile each way from the nearest M25 junction, and a fixed total. Signed off in writing before the diary is reserved.
4. 4
   Arrival, jetting, and final clean
   Jet/vac unit and CIPP rig on site. Host pipe re-cleaned, root cut where present, and any debris vacuumed out. Final CCTV pass to confirm the bore is clean enough to accept the liner.
5. 5
   Liner impregnation
   Resin volume calculated per metre, liner laid out, vacuum-impregnated under controlled conditions with the manufacturer-specified pot life. UV liners loaded into the inversion drum, steam liners into the calibration sleeve.
6. 6
   Liner installed and cured
   Liner inverted or winched into the host pipe under controlled air pressure. UV light-train drawn through, or controlled steam injection started, until the resin reaches full cure per the resin technical sheet.
7. 7
   End-cutting and lateral reinstatement
   Liner ends trimmed flush at the chambers, and lateral connections reinstated using a tracked robotic cutter back to the original profile.
8. 8
   Post-install CCTV and handover
   Final tracked CCTV of the entire lined run, supplied as MP4 plus a written report referencing BS EN 13566 compliance and a 50-year design-life statement for the resin system used.
