Collapsed Drain Repair Sutton Coldfield | No Dig Fix
A Maney property had a fully collapsed drain under the garden. See what the CCTV found and how we relined it without lifting a single slab.
A call came in from a homeowner on one of the older streets off Maney Hill Road. Slow drainage throughout the ground floor, a faint smell near the utility room, and a patch of lawn that had started to feel soft underfoot. They'd had the drains rodded twice by another company in the past year. Both times it cleared briefly, then the symptoms returned.
That pattern, blockage, clear, blockage again, almost always means the obstruction is a symptom, not the cause. Something structural is going on.
What the camera found
We pushed the CCTV camera into the inspection chamber at the rear of the property and ran it along the drain towards the street. The first six metres looked rough but serviceable: some scaling, a couple of slightly displaced joints. Then, at around eight metres in, the picture told a different story.
A section of clay pipe, approximately 1.2 metres long, had partially collapsed. The crown of the pipe had fractured and folded inward, reducing the bore by roughly 60%. Silt and debris were backing up behind it every time the drain was used, clearing when pressure built sufficiently, then backing up again. Classic slow-drain cycle.
The pipe was running beneath a section of garden and, critically, under a section of original Victorian brickwork at the corner of the house. Digging it out the traditional way would have meant breaking through the garden, exposing the brickwork, and almost certainly disturbing the footings of a bay window. Not a conversation anyone wants to have.
The condition grading
We use WRc (Water Research Centre) defect grading on every CCTV survey. It gives the homeowner a clear picture of severity and urgency, not our word against theirs.
| Pipe section | Defect found | WRc grade | Action needed |
|---|---|---|---|
| 0 to 6 m | Joint displacement, light scaling | Grade 2 | Monitor, descale |
| 6 to 7.2 m | Partial collapse, crown fracture | Grade 5 | Immediate repair |
| 7.2 m to boundary | Minor root ingress, intact bore | Grade 3 | Root cut, monitor |
Grade 5 is the top of the scale. It means the pipe can fail completely at any point and is already affecting flow. There's no version of "leave it a bit longer" that ends well.
What we did
No-dig drain relining. Specifically, a cured-in-place pipe (CIPP) liner inserted through the existing inspection chamber.
The process, without the sales language, is this: a felt tube saturated with epoxy resin is inverted into the damaged pipe using water pressure. It folds around the collapsed section, pressed hard against whatever pipe wall remains. UV light is then run through the liner to cure the resin. Once set, you have a new, smooth-bore pipe formed inside the old one, bonded to it, continuous with the host pipe at each end.
The whole repair took around four hours on site. We jet-washed the pipe beforehand to clear the silt build-up, ran the liner through, cured it, then put the camera back in to confirm the bore was clear and the liner had seated correctly.
The post-repair footage showed a clean, unobstructed run from the chamber to the boundary. No soft underfoot garden. No broken brickwork. No disruption to the bay window at all.
The lesson for any Sutton Coldfield homeowner
Most of Maney, Tudor Hill and Whitehouse Common sits on Victorian-era drainage. Clay pipes, laid when this area was first developed, are now well over a hundred years old. They were built to last, and many have. But age, ground movement, and the root systems of mature trees take their toll.
If a drain keeps blocking after clearance, particularly in a property of this age, spend the money on a CCTV survey before spending it on more rodding. You might get a grade 2 result and a clean bill of health. Or you might find what we found on Maney Hill Road, and catch a Grade 5 collapse before the whole run fails.
Relining work at Drainsco carries a 20-year guarantee. That's on the repair itself, not on future blockages caused by what you put down the drain, but it's a meaningful assurance on the structural fix.
Drainsco covers all B72 to B76 postcodes, Sutton Coldfield and the surrounding villages. Engineers are available 24/7, there's no call-out fee, and you'll get a clear price before we start any work.
