WRc-Compliant Drain Relining

No-Dig Drain Relining London

Our London drain relining service is a CCTV survey-led procedure. Every project begins with a comprehensive internal inspection using high-resolution cameras to establish a precise WRc-style defect classification for the existing pipeline.

This diagnostic methodology ensures the structural integrity assessment is objective and documented. The resulting video and written report form the technical basis for determining the necessity and specification of the relining solution.

We provide this documented evidence, essential for property transactions, landlord compliance, and commercial property management. The no-dig epoxy resin relining process restores structural integrity with minimal disruption to your London property.

Pricing is structured based on the diagnostic survey findings, including pipe diameter, length of the defective section, and the complexity of access. A formal quotation follows the initial CCTV survey and defect report.

What you get

CCTV Survey-First Methodology: Every relining project is predicated on a full-diagnostic CCTV survey, never assumed.
WRc-Style Reporting: Defects are classified and documented to industry-standard protocols for unambiguous technical communication.
Insurance-Grade Documentation: High-resolution video evidence and detailed written reports support claims and dispute resolution.
Precise Resin Calibration: Epoxy resin mix and cure times are calculated based on the surveyed pipe diameter, length, and defect severity.
Minimal Ingress/Exit Excavation: Access typically requires only a small excavation at the launch and reception points, confirmed via survey.
Post-Relining CCTV Verification: A final survey provides documented proof of the new pipe's integrity and flow characteristics.

How it works

A method, not a guess

Diagnostic CCTV Survey

Our engineers deploy a push-rod or crawler-mounted CCTV camera to conduct a full-length inspection of the defective drain. This records high-definition video for analysis and reporting.

Defect Classification & Report

We analyse the footage to classify defects (e.g., fractures, displaced joints, root ingress) according to WRc guidelines. A formal report with timestamps and defect codes is produced.

Resin Liner Installation

Based on the survey data, a resin-impregnated liner is calibrated and inverted or pulled into place. It is then cured in situ using hot water or UV light to form a rigid, jointless new pipe.

Post-Installation Verification

A final CCTV survey is conducted inside the newly relined pipe. This verifies complete installation, provides evidence of restored integrity, and is included in the completion documentation.

Questions

Drain Relining FAQs for London homeowners

Why is a CCTV survey mandatory before drain relining?

A CCTV survey provides the only objective basis for a structural diagnosis. It confirms the suitability of relining, identifies precise defect locations for targeted repair, and establishes the baseline condition for all technical documentation and warranty provision.

What does WRc-style defect classification mean for my report?

It means defects are coded using a standardised system (e.g., 'BF' for broken pipe, 'DJ' for displaced joint). This eliminates ambiguity, providing clear, technical language suitable for conveyancing, landlord-tenant communications, and insurance assessments.

How does relining documentation support a property transaction?

The pre- and post-relining CCTV surveys and the accompanying engineer's report constitute a permanent record of the drain's condition and the remedial work undertaken. This is critical evidence for solicitors during conveyancing to demonstrate resolution of drainage issues.

Can relining be used for all drain defects in London?

No. The CCTV survey determines suitability. Severe collapses, heavily misaligned sections, or pipes with significant loss of structural shape may preclude relining. The survey report will clearly indicate if traditional excavation is the technically correct solution.

What is included in the post-work documentation for landlords?

Landlords receive a comprehensive dossier including the initial defect report with WRc codes, the final verification CCTV survey video, a method statement for the works undertaken, and a warranty certificate for the new lining, supporting statutory compliance and asset management.
