Drain Relining & No-Dig Repair in Cumbria

When pipes are cracked, misaligned, or suffering from root damage, traditional digging can be expensive, disruptive, and destructive. At Unblock Cumbria, we specialise in drain relining — a trenchless, no-dig method that rehabilitates your pipes without tearing up your yard, driveway, or landscaping. We offer this across Cumbria and the Scottish Borders, ensuring long-lasting repairs with minimal fuss.

Using advanced resin-liner technology, we apply a seamless inner sleeve within the damaged section of the existing pipe. Once cured, it forms a new structurally sound pipe inside the old one — restoring strength and flow while avoiding invasive works.

Drain Relining Services

  • CIPP (Cured-In-Place Pipe) relining for continuous pipe runs

  • Spot patch relining for localised defects

  • Joint sealing and joint-over-liner techniques

  • Root-cutting and lining integration to block re-entry

  • Full CCTV surveys before and after relining

  • Pressure testing and quality assurance

  • Warranty and follow-up inspection services

  • Repairs suitable for domestic, commercial, and industrial drainage

We match the liner to the diameter, pipe type, and defect severity — delivering reliable performance, structural integrity, and long-term insulation against future damage.

Benefits of Drain Relining

  • Minimal disruption — No trenches, no extensive digging, no major landscaping impact

  • Cost-effective — Relining costs significantly less than full pipe replacement in most cases

  • Fast throughput — Repairs often completed in hours, not days

  • Durability & strength — Relined pipes can last 20+ years or more

  • Prevents root ingress — Sealed liner resists future root penetration

  • Smooth internal finish — Reduces friction, silt build-up, and improves flow

Relining is ideal when pipe alignment is intact but structural integrity or leak resistance is lost.

Why Choose Us?

  • Accredited & experienced lining engineers (NADC, CHAS, SafeContractor)

  • Complete “survey → reline → verify” approach to ensure success

  • Transparent quotes, documented evidence, and warranties

  • Use of premium resin liners and curing systems

  • Capability for both full-line and patch repairs

  • Minimal interruption to access, landscape or property structure

We emphasise the right fix over quick patches — delivering strong, lasting relined systems that revive performance without disruption.

Frequently asked questions

What is CIPP relining?

CIPP (Cured-In-Place Pipe) involves inserting a resin-impregnated liner into the existing damaged pipe and curing it in place (via heat, UV, or ambient cure) to form a new pipe-within-a-pipe.

Can every pipe be relined?

Most pipes qualify, but extreme damage (full collapse), significant offset joints, or misalignment may require full replacement. We assess via CCTV first.

How long does relining take?

For typical domestic runs, relining often completes within 2–6 hours, including cure time and verification inspection.

Will relining fix leaks or broken pipes?

Yes — when the damage is not extreme. Relining seals cracks, pinholes, small joint separations, and provides a new watertight inner surface. It is not suitable when full replacement is required.

Is relining more expensive than patch repair?

Relining cost is higher than a simple patch in localised areas, but for longer damaged runs it’s far more cost-effective than excavating and replacing entire pipe sections.

How long will a relined pipe last?

With proper materials and installation, relined pipes can last 20–40 years or more. We also offer post-inspection and warranty support.
