No-Dig Drain Relining
Location: Accrington, Lancashire Property Type: Residential Driveway Timeframe: Completed in 1 Day

Restoring a Fractured Drain Under Block Paving Without Excavation

The Challenge: A homeowner in Accrington experienced repeated ground-floor toilet backups and unpleasant drain odours. Initial investigation by an independent handyman suggested excavating the newly laid block-paved driveway, costing upwards of £3,000 in disruption and repaving work.

Our Investigation: Drain Medics conducted a high-definition CCTV Drain Survey. We pinpointed multiple circumferential fractures and displaced joints in a 100mm glazed clay pipe running directly beneath the driveway, likely caused by heavy vehicular weight and ground movement over time.

The Solution: Instead of costly excavation, our team performed high-pressure water jetting to clear scale and debris before installing a Cured-In-Place Pipe (CIPP Drain Relining) system. Using resin-impregnated felt liner calibrated with air inversion, we formed a seamless, structurally sound pipe inside the old damaged line.

Result: Saved customer over £2,000 & backed by 10-year guarantee.

Drain Pest Control
Location: Greater Manchester Property Type: Commercial Food Facility Timeframe: 24-Hour Eradication

Eradicating Commercial Rat Infestation via Drainage Network Proofing

The Challenge: A commercial restaurant in Greater Manchester reported persistent rat sightings inside their store cupboard and kitchen perimeter. Traditional pest control technicians laid poison repeatedly, but rodents kept returning because the core entry route remained open.

Our Investigation: Drain Medics was called to investigate the underground infrastructure. Using specialized pan-and-tilt push cameras and non-toxic smoke testing, we uncovered a disused inspection junction where rats were gnawing through compromised clay pipe walls and burrowing up under the subfloor.

The Solution: We permanently sealed off the redundant connection using resin injection patch repair. Furthermore, we installed a precision-engineered stainless steel single-way Rat Blocker inside the primary inspection chamber, allowing waste to flow freely out while preventing pests from entering.

Result: 100% rodent proofing achieved & Environmental Health compliance restored.

Emergency Excavation
Location: Clitheroe, East Lancashire Property Type: Victorian Semi-Detached Timeframe: Rapid 48-Hour Turnaround

Emergency Excavation & Replacement of Collapsed Clay Main Sewer

The Challenge: An urgent 24/7 call-out came from a homeowner in Clitheroe facing raw sewage pooling in their garden due to a total main sewer collapse. Immediate ground stabilization and pipe renewal were required to protect the building foundations and health standards.

Our Investigation: We attended within 60 minutes. An immediate camera inspection revealed a completely crushed 150mm main pipe line at a depth of 1.4 metres, rendering trenchless relining impossible due to total collapse.

The Solution: Drain Medics carried out a precise, controlled trench excavation following UK Building Regulations Part H. We safely exposed the damaged crushed section, shored up the trench walls, replaced the collapsed clay pipe with heavy-duty PVC drainage, and integrated a modern polypropylene inspection chamber for future access.

Result: Ground backfilled, reinstated, and backed by £5M public liability assurance.

Heavy FOG Jetting
Location: Blackburn, East Lancashire Property Type: Industrial Food Park Timeframe: Same-Day Emergency Clear

Commercial Drain Jetting & Fat, Oil, Grease (FOG) Extraction

The Challenge: A heavy build-up of Fat, Oil, and Grease (FOG) combined with silt had completely blocked the main commercial discharge sewer serving three takeaway outlets in Blackburn, causing sink backing and external overflow.

Our Solution: Drain Medics deployed our specialized van-mounted high-pressure water jetting unit operating at over 3,000 PSI with specialized backward-firing FOG nozzles. We systematically cut through hardened grease deposits, restored full bore flow, and conducted electro-mechanical descaling to remove encrusted scale from pipe walls.

Preventative Plan: To maintain compliance with local water authority regulations (United Utilities guidance), we established a biannual preventative maintenance schedule for regular high-pressure jetting.

Result: Zero downtime for business owners & full flow restored.

Home Buyer Survey & Root Removal
Location: Preston, Lancashire Property Type: Residential Conveyancing Timeframe: 24-Hour Survey & Report

Pre-Purchase CCTV Survey Uncovers Severe Tree Root Ingress

The Challenge: A prospective home buyer commissioned a pre-purchase drainage inspection prior to exchanging contracts on a traditional property in Preston with mature oak trees nearby.

Our Findings: Our survey revealed severe root mass intrusion occupying 80% of the pipe bore across a 6-metre section, along with displaced pipe joints. Without this survey, the buyer would have faced immediate post-purchase drainage failure.

The Resolution: We used robotic mechanical root cutting tools to clear the root mass without damaging the original host pipe, followed by localized resin patch lining to seal the joints against future root penetration. The full video evidence and formal report allowed the buyer to successfully negotiate an £1,800 repair reduction on the property purchase price.

Result: Saved home buyer thousands before contract exchange.

Frequently Asked Case Study Questions

Learn more about how we diagnose, quote, and resolve complex drainage issues.

How quickly can Drain Medics attend an emergency project?

Our rapid response vehicles are stationed strategically across Accrington, Manchester, Blackburn, Preston, and East Lancashire. We provide 24/7, 365-day emergency cover and aim to arrive on site within 60 to 90 minutes.

Is no-dig CIPP drain relining suitable for all pipe damage?

CIPP relining is ideal for cracked, fractured, or root-intruded drains. However, if a pipe is completely collapsed or structurally crushed (as seen in Case Study 3), traditional excavation under UK Building Regulations Part H is required. A preliminary CCTV survey determines the exact right method.

How do rat blockers stop rodents without blocking waste?

Rat blockers feature a stainless-steel single-direction flap mechanism. Solid and liquid waste pushes the flap open easily from the property side, but the flap locks tight against external entry, preventing rats from entering the system.

Can CCTV drain surveys be used for insurance claims or house buying?

Yes. Drain Medics provides fully detailed CCTV video footage, site maps, and written diagnostic reports suitable for insurance claim assessment and formal home buyer mortgage surveys.
