What Is Drain Re-Lining?
Drain relining — also known as cured-in-place pipe (CIPP) lining — is a trenchless repair method that installs a new structural liner inside your existing drain pipe. The liner is made of resin-saturated felt or fibreglass, inserted into the damaged pipe, inflated against the pipe walls, and cured to form a seamless, jointless pipe-within-a-pipe.
This method repairs cracks, fractures, displaced joints, root ingress points, and minor structural defects without excavation. The cured liner has a smooth internal surface that improves flow, resists root penetration, and prevents future ground water infiltration.
Relining is suitable for pipes from 100mm to 600mm in diameter, including domestic waste pipes, surface water drains, and combined drainage systems. It works on clay, PVC, concrete, cast iron, and pitch fibre pipe materials.
The process is significantly faster, cleaner, and less expensive than traditional excavation and pipe replacement — particularly for drains running under driveways, patios, buildings, or landscaped gardens where the cost of reinstatement would be substantial.
What Happens When Damaged Drains Are Left Unrepaired?
Cracked or displaced drain pipes do not heal. Every week left unrepaired, ground water infiltrates through the defects, washing soil particles into the pipe. This process — called erosion voids — gradually removes the soil supporting the pipe, your driveway, your patio, or your foundations.
Tree roots exploit cracks and displaced joints aggressively. A hairline fracture provides enough moisture signal for roots to enter and expand. Within months, a minor joint displacement becomes a root-packed obstruction causing recurring blockages and further pipe damage.
Leaking drains in clay soil cause ground heave. Leaking drains in sandy soil cause subsidence. Both scenarios can damage your property's foundations. Insurance claims for subsidence require evidence that the drainage system was properly maintained — unrepaired known defects will void your claim.
Traditional excavation to replace a damaged drain section under a driveway can cost £4,000–£12,000 including reinstatement. The same repair using relining typically costs £1,500–£4,000 with no reinstatement required. Delaying the decision doesn't reduce the cost — it increases it.
How We Re-Line Your Drain
CCTV Pre-Survey
We inspect the drain using HD cameras to confirm the location, extent, and nature of the damage. This determines whether relining is viable and identifies any preparation work needed.
Drain Preparation
We clean the pipe thoroughly using high-pressure jetting to remove debris, scale, roots, and deposits. The pipe must be clean for the liner to bond properly. Root cutting is performed if necessary.
Liner Installation
The resin-saturated liner is pulled or inverted into position inside the pipe, precisely covering the damaged section. The liner is inflated against the pipe walls using air pressure to ensure full contact.
Curing
The resin cures to form a rigid, structural pipe-within-a-pipe. Curing methods include ambient cure (natural hardening over several hours) or UV/hot water cure (accelerated curing in under an hour) depending on the specification.
Post-Lining CCTV Check
We reinspect the lined section with CCTV to confirm the liner is fully bonded, free of wrinkles or defects, and that all lateral connections are open and flowing correctly. You receive the footage and a written completion report.
Why Relining Beats Excavation
No Excavation
Your driveway, patio, garden, and property remain untouched. No diggers, no spoil heaps, no reinstatement costs, no weeks of disruption.
50-Year Design Life
Cured-in-place liners are designed to last 50+ years. The seamless, jointless construction eliminates the weak points that caused the original failure.
Improved Flow
The smooth internal surface of the cured liner reduces friction and improves water flow compared to the original pipe — particularly in older clay and cast iron systems.
Root-Proof
The seamless construction eliminates joints — the primary entry point for tree roots. Once lined, roots cannot penetrate the pipe.
Cost-Effective
Relining typically costs 40–60% less than excavation and replacement when reinstatement costs are factored in. For drains under buildings or structures, the savings are even greater.
Fast Completion
Most domestic relining jobs are completed in a single day. Your drainage system is back in service within hours, not weeks.
Drain Re-Lining: Materials, Methods & Applications
We use several relining systems depending on the pipe diameter, defect type, and access conditions. Patch liners repair isolated defects — a single crack or displaced joint — without lining the entire pipe run. Full liners cover the complete section from access point to access point, creating a continuous new pipe.
Liner materials include polyester felt saturated with epoxy or polyester resin (standard domestic applications), fibreglass reinforced liners (structural rehabilitation of severely damaged pipes), and silicate resin liners (chemical-resistant applications for commercial or industrial drainage).
Curing methods affect both cost and turnaround time. Ambient cure liners harden naturally over 4–12 hours and are the most cost-effective option for routine domestic repairs. UV-cured liners use ultraviolet light to harden the resin in under an hour, allowing same-day reinstatement. Hot water cure and steam cure methods offer precise temperature control for critical applications.
Relining is effective for cracks, fractures, displaced joints (up to approximately 20mm displacement), root ingress points, and minor deformation. It is not suitable for fully collapsed pipes, severely deformed sections (where the pipe has lost more than 40% of its original shape), or pipes with major structural failure requiring excavation.
For pitch fibre pipes — common in UK properties built between 1945 and 1975 — relining is often the preferred solution. Pitch fibre deteriorates over time, becoming soft and deforming under soil pressure. Relining restores structural rigidity without the cost and disruption of excavating and replacing the entire pitch fibre system.
Lateral connections — the junctions where branch pipes enter the main drain — require careful management during relining. Our installation method preserves lateral connections by reopening them after the liner has cured, using robotic cutting equipment operated through the lined pipe. This ensures all connected pipes continue to flow correctly.
We provide a material and workmanship guarantee on all relining installations. The guarantee period depends on the system used and the condition of the host pipe. Typical guarantees range from 10 to 25 years, with the liner itself designed to last 50+ years.
