CIPP (Cured-In-Place-Pipe) relining is a trenchless repair method that installs a new pipe inside your existing damaged pipe. A flexible liner made of polyester or fibreglass felt is saturated with a structural thermosetting resin, inserted into the drain, and inflated to press firmly against the pipe walls. The resin is then cured (hardened) using hot water, steam, or UV light, forming a rigid, jointless, corrosion-resistant pipe-within-a-pipe.

1. CCTV survey — The damaged drain is surveyed to map every defect, measure pipe diameter, and confirm that relining is the appropriate repair method.
2. Pipe preparation — The drain is cleared using jetting and/or rodding to remove blockages, debris, and root mass. For pitch fibre drains, re-rounding is carried out to restore the circular profile.
3. Liner installation — The resin-saturated liner is pulled or inverted into the pipe through an existing access point (manhole or inspection chamber).
4. Inflation — The liner is inflated using air pressure to push it tightly against the host pipe walls, conforming to the pipe’s shape and sealing every crack, fracture, and joint.
5. Curing — The resin is cured to form a hard, structural pipe. Curing methods include circulating hot water, steam, or UV light, depending on the resin system.
6. Reconnection & verification — Lateral connections (branches feeding into the relined pipe) are reopened using a robotic cutter. A final CCTV survey verifies the completed reline.

• No excavation required — No digging up gardens, driveways, floors, or pathways. All work is carried out through existing access points.
• 50+ year expected lifespan — The cured liner is a structural, load-bearing pipe designed for long-term service.
• Jointless construction — The liner forms a seamless pipe with no joints, eliminating the most common root entry and displacement points.
• Chemical & corrosion resistant — The cured resin is resistant to chemical attack, scaling, and biological degradation.
• Improved flow characteristics — The smooth internal surface of the liner can actually improve flow rates compared to the original pipe.
• 10-year DrainsCo guarantee — Covering both the liner material and our workmanship.

CIPP relining is effective for cracked, fractured, root-damaged, displaced, corroded, and deformed (pitch fibre) pipes from 100mm to 600mm+ diameter. It is not suitable for fully collapsed pipes where the bore has been lost, or in very rare cases where the pipe material cannot support a liner. A CCTV survey confirms suitability.

A patch repair is a targeted, no-dig repair that addresses a single defect without relining the entire pipe. A short section of resin-impregnated material is positioned over the specific crack, fracture, or damaged joint using a packer (inflatable positioning device), then cured in place to form a localised structural repair.

• A single crack or fracture — One isolated defect on an otherwise sound pipe doesn’t justify a full reline.
• An individual displaced joint — One joint that has shifted, allowing root intrusion or leakage, while the rest of the system is intact.
• A root entry point — Where roots are entering through a specific joint or crack that can be sealed by a patch.
• Budget-conscious repair — Patch repair is more affordable than full relining when the damage is localised.

Patch repairs carry the same 10-year DrainsCo guarantee as full CIPP relining, covering the repaired section.

1. CCTV location of the defect — The exact position, size, and nature of the defect are mapped on camera.
2. Pipe cleaning — The affected area is jetted clean to ensure the patch bonds securely.
3. Patch preparation — A resin-saturated patch of the correct size is prepared and loaded onto the positioning packer.
4. Positioning & inflation — The packer is advanced to the exact defect location using CCTV guidance and inflated, pressing the patch against the pipe wall over the defect.
5. Curing & verification — The resin cures to form a hard, bonded repair. A final CCTV survey confirms the patch is correctly placed and sealed.
