C4 Plus Drainage Ltd
Expert drainage solutions for residential and commercial properties — fast, reliable no-dig drain repair with less mess and disruption.
Damaged drains can cause leaks, bad smells, slow flow, and repeat blockages. Drain relining repairs damaged pipes from the inside. It avoids digging up floors, paths, or driveways. This no-dig method helps us reduce mess and disruption.
Cracks, failed joints, and root damage can reduce the performance of a drain pipe. A correct diagnosis helps prevent unnecessary work. We inspect the affected pipe before drain relining. This helps us find the damage and its location.
Hidden pipe damage is difficult to assess from ground level. A drain CCTV inspection provides a clear view inside the drainage system. It can identify cracks, gaps, root entry, displaced joints, and other faults. Accurate drain surveys also help us decide whether relining is suitable.
A resin liner is inserted into the existing drain and cured against its inner wall. Once cured, the liner forms a new surface inside the old pipe. This no-dig drain repair method treats many pipe defects and helps avoid removing the existing pipe — reducing digging, mess, and reinstatement work.
Local damage does not always require a full liner. Drain patch lining targets a specific damaged section of pipe. A resin patch is positioned over the defect and cured to create a strong local repair for small cracks, holes, and failed joints.
A lasting repair depends on an accurate inspection and suitable installation. Clear advice is important when choosing drainage contractors — and each stage remains clear with our approach.
Drain relining repairs damage inside the existing pipe and can reduce the need for digging up gardens, floors, paths, and driveways.
A no-dig pipe repair keeps the existing pipe in place while creating a new internal surface — ideal for homes and commercial properties.
Repairing the existing pipe can reduce major reinstatement. Relining can seal cracks, gaps, and leaks and improve ageing pipework.
Suitable faults may not need full pipe replacement. Our trenchless drain repair offers a practical alternative to excavation.

Before
PreparationDuringAfterDrainage faults affect both older and newer properties. Our London and Surrey drainage services include detailed inspections to find the cause — covering homes, commercial sites, and private drainage systems.
Recurring blockages or leaks can indicate damage within the drainage system. Early inspection can identify the fault before further problems develop. Drain relining may provide a less disruptive way to restore the affected pipe. Need professional drainage services, sewer relining, or no-dig repair? Contact us to arrange an assessment — we'll inspect the pipe and recommend a suitable repair.
“I was very impressed by the work of Ryan and his team. They attended promptly. Used a metal detector to locate a manhole cover hidden two feet under soil on a hill in my front garden. Having located the blocked drain they cleared the blockage quickly and cleanly advising it was caused by flushing baby wipes etc down the toilet. He also advised I could pay for a more extensive cleaning of the drainage system and CCTV report at a later date if I wanted to. Two previous drainage experts were unable to locate the problem. One offered to conduct an expensive survey. Ryan saved me a lot of money.”

“Ryan and his colleague did a great job clearing the blockage in our drains/sewer. Unfortunately, a rat popped its head up while he was working and there were signs of a rat infestation which will need further investigation. I have no hesitation in recommending Ryan and will book him for the future work that needs carrying out. What was really commendable was that he didn’t charge for the job as he is doing such work free of charge during lockdown for the over 65’s and vulnerable people. A very nice man.”

“I had been recommended the guys at C4 previously. They came to our local school to fix an emergency drainage problem. We spoke to Ryan directly, and one of his team arrived on the same day! They managed to put a temporary quick fix in place, until they could rectify the problem permanently. Amazing service, quick, efficient and polite. Always happy to help out. I wouldn’t hesitate to recommend them in the future. Thanks again Ryan & the team at C4 Plus Drainage.”
