What Is Bluelight Pipe Relining?

Repair Damaged Pipes From the Inside.

Bluelight drain relining is a trenchless method used to rehabilitate damaged or deteriorating underground pipework without the extensive excavation associated with traditional drain repairs.

A flexible liner coated with specially formulated resin is inserted into the existing pipe. Once positioned and inflated, it moulds to the internal wall of the pipe and is cured using blue LED light, creating a new continuous inner structure.

The process can seal cracks, leaks and other defects while helping restore structural integrity and flow characteristics within the existing drainage system. It forms part of our wider drain relining capability for repairing damaged pipework without conventional replacement.

KD Drainage and Asbestos offers Bluelight lining as a specialist repair option across the South East for both domestic and commercial drainage projects.

Key Advantages

Trenchless repair with considerably less disruption.

✓ No major excavation required

LED Curing

How the System Works

Bluelight Uses Controlled LED Curing Inside the Pipe.

Before relining is recommended, a CCTV drain survey can be used to inspect the condition, route and dimensions of the pipework and establish whether trenchless repair is suitable.

The Bluelight system uses LED heads operating at a blue-light wavelength of approximately 450nm. The liner is combined with a specialist resin containing a photo-initiator designed to react to that light source.

Once the liner has been correctly positioned, the LED curing head passes through the pipework and activates the resin, allowing the liner to harden in a controlled and comparatively short period of time.

This combines the flexibility of modern liner systems with the speed and control of light curing, making it particularly useful for smaller-diameter wastewater pipes and more complex drainage layouts.

Bluelight Technology

A Faster, More Controlled Way to Cure CIPP Liners.

Traditional CIPP curing can involve heat, water or extended cure times. Bluelight uses LED technology to activate the resin directly within the liner.

The system also allows the liner to be checked before curing and can reduce the time equipment needs to remain on site.

For suitable applications, this can mean faster installation, less disruption and a more efficient rehabilitation process than excavating and replacing entire sections of drainage.

Benefits of Bluelight Pipe Lining

Designed to Reduce Downtime, Excavation and Disruption.

Rapid Curing

LED curing can harden the resin in a relatively short period, reducing installation time and downtime.

Durable Repair

Creates a continuous inner liner designed to seal cracks, leaks and other defects.

Versatile

Suitable for a range of pipe materials, diameters, bends and drainage layouts.

Low Space Requirement

Can be particularly useful where access is restricted or excavation would be disruptive.

Reduced Disruption

The trenchless approach can avoid much of the digging associated with conventional pipe replacement.

Case Study

Six Tower Blocks. 14+ Storeys. Minimal Disruption.

A commercial Bluelight lining project completed for Axis Europe PLC after deterioration was identified within vertical rainwater pipework across six tower blocks in Essex.

Project Background

Deteriorating rainwater pipes across six Essex tower blocks.

KD Drainage and Asbestos was engaged by Axis Europe PLC to carry out CCTV surveys of accessible drainage at six residential tower blocks.

The investigation identified deterioration within the vertical rainwater pipework. Because conventional replacement would have caused significant disruption to residents, CIPP rehabilitation was selected as the repair method.

The Challenge

The pipework extended vertically from more than 14 storeys, creating a significant access and logistics challenge for getting the relining equipment safely into position.

The Solution

The Bluelight system and PAA-F inversion liner were selected to rehabilitate six lengths of 150mm pitch-fibre rainwater pipe.

Internal measurements were taken to confirm pipe diameter and liner lengths before the liner design was developed with the material supplier to meet structural and hydraulic requirements.

Mast-climber platforms were used to safely transfer the equipment to roof level. Pre-lining CCTV surveys and lateral measurements were then completed before installation.

The Result

Completed safely, on time and with minimal disruption.

All liners were installed and cured to specification, lateral connections were reopened and post-installation CCTV surveys were completed before the site was stripped down. The project was delivered safely, with minimal disruption, on time and within budget.

Commercial Capability

Suitable for complex and access-sensitive projects.

The project demonstrates how trenchless Bluelight rehabilitation can be used where conventional excavation or pipe replacement would create substantial disruption.

Bluelight Lining FAQs

Common Questions About LED Pipe Relining.

What lengths can be cured?

Standard installations can typically cure pipe lengths up to around 100 metres, although longer lengths may be possible depending on the project and system design.

What pipe materials can be relined?

Bluelight lining can be used with a range of drainage materials including PVC, clay, concrete and cast iron, subject to inspection and suitability.

How long can a Bluelight repair last?

A correctly designed and installed liner is intended to provide long-term rehabilitation of the existing pipework, with service life depending on the system, installation and site conditions.

Is Bluelight suitable for every damaged pipe?

No. Relining may not be appropriate where a pipe is severely collapsed, badly displaced or structurally unsuitable. A CCTV inspection and engineering assessment are used to determine whether lining is a viable repair option.

Can Bluelight lining be used commercially?

Yes. KD Drainage uses Bluelight lining for domestic work and larger commercial projects where trenchless rehabilitation is suitable.

Does Bluelight lining work around bends?

The system is designed for use across a range of pipe layouts, including bends and junctions, although the exact suitability depends on pipe diameter, geometry and condition.

Bluelight Pipe Relining

Need to Repair Damaged Pipework Without Major Excavation?

If a CCTV investigation has identified cracked, leaking or deteriorating pipework, Bluelight lining may provide a trenchless alternative to conventional excavation and replacement.

Where relining is not suitable because the pipework is severely displaced or collapsed, our wider drain repair services can provide an alternative solution.

Speak to KD Drainage and we can assess the drainage system and advise whether LED-cured CIPP lining is appropriate for the project.

 Trustindex verifies that the original source of the review is Google. As a longstanding Chartered Surveyor, Chartered Building Engineer and former Building Inspector, I would state that this company were the most impressive in all respects relative to the investigation, conclusion, and swift rectification of the failed system at my home. The chaps that attended were extremely professional and unusually very competent in their duties from start to completion. I would recommend them wholeheartedly on projects ongoing.
