Underground Drainage: Buried but Not Forgotten

When you’re working above ground, a small mistake might mean a quick fix. But once you’ve filled in that trench, there’s no going back. That’s why with underground drainage, it pays to do it right first time — because nobody wants to be digging it up again six months later.

You Only Get One Shot Underground

If it’s going to live under your driveway, patio, or extension, it needs to last. Cheap drainage pipes might look similar, but once they’re buried, small differences in quality can turn into big problems — leaks, blockages, or collapsed joints that you can’t see until they’ve made a mess of your garden.

Every pipe and fitting we sell is FloPlast quality — BS EN 1401-1 Kitemark certified and made in the UK. That means precise socket fits, watertight seals, and high-impact PVC-U that’s built to take pressure from soil and ground movement.It’s the kind of reliability that keeps your shovel in the shed, where it belongs.

Designed to Last a Lifetime

FloPlast underground drainage isn’t just strong — it’s smartly engineered. The pipes flex just enough to handle seasonal shifts and heavy loads without cracking, and the smooth internal walls help prevent silt build-up.

Every bend, junction and gully is manufactured to the same standard, so installation is simple, connections are secure, and flow is uninterrupted. No wrestling with mismatched parts — everything clicks, locks, and lasts.

Real-World Reliability

Whether you’re connecting a rainwater downpipe, installing a new gully, or linking into an existing chamber, FloPlast 110mm underground pipe is the trade choice for good reason.It’s trusted by builders, groundworkers, and DIYers alike — not because it’s flashy, but because it works.You install it once, cover it up, and never have to think about it again.

Buy Once, Dig Once

There’s a saying we stand by: “Buy cheap, buy twice.”Nowhere is that truer than with underground drainage. The cost of re-digging and replacing a failed system easily outweighs any saving on bargain-bin pipework.

At The Plastics Shed, we only stock drainage products we’d be happy to install ourselves — solid, reliable, and made to outlast the job.
