Collapsed Drain Repair Haywards Heath | No Dig Fix

The call came in on a Wednesday afternoon. A homeowner on one of the newer streets off Bolnore Village Road had noticed the ground near their back fence was sinking slightly, just a shallow dip in the lawn that hadn't been there last spring. Their downstairs toilet was sluggish too, not blocked outright, just slower than it should be. They'd already tried a plunger, poured a kettle of hot water down, and called a general plumber who'd had a look and said it might be worth getting the drains checked properly.

They were right to push it. That soft patch in a garden can mean several things, and not all of them are serious. But combined with a slow toilet, it pointed somewhere specific.

What We Found When We Arrived

I pulled up mid-afternoon, had a quick chat with the owner, then pushed the CCTV camera into the nearest inspection chamber at the side of the house. The first ten metres of drain looked fine, standard 100mm clay pipe running towards the rear of the plot, a little greasy but nothing alarming.

Then the picture changed.

At around eleven metres, the pipe had partially collapsed. Not a crack, not a root intrusion, an actual structural failure where the pipe had buckled inward, narrowing the bore by roughly sixty percent. Just beyond that point, sediment and debris had piled up against the obstruction and the surrounding soil had started to migrate in through the gap, which explained the sinking lawn above it.

Clay pipes of that age aren't unusual out on the Bolnore development's boundary plots, where older runs sometimes meet newer connections. Ground movement, a damp winter, the weight of vehicles on a driveway further along the shared run, any of these can finish off a pipe that's already been under stress for years.

I showed the owner the footage on the monitor. No guesswork, no estimate, they could see it themselves.

The Before

Left alone, this was going to become a full blockage and a larger hole in the garden. It wasn't an emergency yet, but it was close.

How We Fixed It

The owner's first question was the one almost everyone asks. "Do you have to dig up the garden?"

Not for this one. No-dig drain relining, sometimes called cured-in-place pipe lining or CIPP, is exactly what the job called for. Here's how it went.

Step one: clear the run. Before you can reline anything, the pipe has to be clean. I set up the high-pressure water jetter and worked the debris and sediment out through the inspection chamber. This took about forty minutes. The soft ground above the collapse meant I kept the pressure controlled rather than going full bore, no point stressing the pipe further.

Step two: re-survey. Once the line was clear, I ran the camera through again to confirm the exact length of damaged pipe, check for any secondary cracks further along, and make sure there were no other surprises. There weren't. Clean run from about fourteen metres onward.

Step three: insert the liner. A flexible felt liner, pre-saturated with resin, is fed through the pipe from the inspection chamber. It's not a rigid insert, it folds to fit the existing bore and pushes right through the damaged section. Once it's in position, an inflatable bladder expands it out against the pipe walls, holding it tight while the resin cures.

Step four: cure and reinstate. Resin cure time varies with temperature. On that afternoon it took just under ninety minutes. Once cured, the bladder is deflated and pulled back out. What you're left with is effectively a new pipe inside the old one, smooth-walled, root-resistant, and fully structural.

Step five: final CCTV pass. I always run the camera through one more time after a relining job. The owner watched the footage. Smooth bore, no deformation, no gaps at the joints. Job done.

Total time on site: just under four hours.

The After

No trench. No turf lifted. No topsoil mounded up on the patio. The only visible sign that anything had happened was a small spoil pile of the jetting debris, and that bagged up and went with me.

The toilet flushed normally before I'd even packed the van. The owner said it felt different immediately, a proper strong flush rather than the tired gurgle they'd been living with for weeks.

The liner carries a 20-year guarantee on the remedial work. That's not a sales line, it's a documented guarantee on the repair itself. If that relined section fails within twenty years, we come back and fix it. The owner has that in writing.

What This Means for Your Garden

If you've got a soft patch in your lawn, especially near where you'd expect a drain run to pass, don't just fill it with topsoil and move on. That dip is the ground telling you something has shifted below it. It might be a soakaway, it might be a leaking water main, but if you've got any drainage symptoms inside the house at the same time, a CCTV survey is the quickest way to know what you're actually dealing with.

A survey here in the RH16 and RH17 postcodes takes an hour or less in most cases. You get the footage, a plain-English explanation, and a fixed price before anything is agreed. No obligation to use us for the repair.

For most partial collapses caught at this stage, relining is the right answer. Cheaper than excavation, faster, and it doesn't leave your garden looking like a building site.

Drainsco covers Haywards Heath and the surrounding RH postcodes around the clock, engineers available 24/7, no call-out fee, and a clear price before we start. If something doesn't look right in your garden or your drains are behaving oddly, give us a call and we'll take a look.
