Specialist Technical Drainage Solutions
Our engineers operate high-specification plant equipment to inspect, restore, clean, and rehabilitate domestic and commercial underground drainage infrastructure without unnecessary excavation.
CCTV Drain Surveys & Mapping
High-definition WRc-standard inspections utilising Minicam push-rod cameras and Vivax sonde tracking. Essential for pre-purchase property surveys, locating mining subsidence cracks, and network mapping.
No-Dig Drain Relining & Patching
Trenchless rehabilitation using ambient and hot-cure epoxy/silicate resins. We install structural sleeves inside cracked clay or fractured pipework to restore integrity without excavating driveways or lawns.
High-Pressure Water Jetting
Industrial-grade water jetting units up to 4000 PSI to strip heavy grease, mineral encrustation, scale, and silt. Full bore restoration carried out safely without damaging delicate Victorian clay pipework.
Collapsed Drain Repairs & Excavation
When pipework has suffered total structural collapse and cannot be lined, our team undertakes pinpoint excavations, modern uPVC replacement, benching repairs, and complete surface reinstatement.

Understanding Private Responsibility vs Northumbrian Water
Property owners across Sunderland, Newcastle, Gateshead, Durham, and Middlesbrough are often unclear where their drainage responsibility begins and ends. Under the 2011 Private Sewers Transfer Regulations:
- ✔ Private Drains: Pipework inside your legal boundary serving only your individual property remains your responsibility to maintain, unblock, and repair.
- ✔ Shared Lateral Drains & Public Sewers: Once a pipe carries waste from two or more properties, or crosses beyond your boundary, ownership transfers to Northumbrian Water.
- ✔ Regional Ground Conditions: In older Victorian terraces (such as Millfield or Jesmond), back-lane bottlenecks and coal-mining subsidence regularly cause shear fractures in salt-glazed clay that require pinpoint CCTV surveys before undertaking repairs.
APJ Drainage diagnoses the precise location of your defect via sonde tracing and provides the photographic evidence required if an issue is statutory Northumbrian Water infrastructure.

Frequently Asked Questions
Clear, practical answers about our drainage diagnostics, pricing, and structural repairs.
How do I know if a blocked drain is my responsibility or Northumbrian Water's?
If a blockage occurs in a pipe that is inside your property boundary and serves only your home, it is a private drain and you are responsible for clearing it. If the pipe is shared with a neighbour before leaving the boundary, or is located outside your property boundary in the road or pavement, it is a public lateral sewer managed by Northumbrian Water. We can quickly inspect your inspection chambers to determine exact liability.
What is no-dig drain relining and how does it save money?
No-dig drain relining is a trenchless repair technique where an epoxy or silicate resin-impregnated felt sleeve is inverted or pulled into the damaged pipe. Once inflated and cured, it creates a rigid, waterproof pipe-within-a-pipe that seals cracks, restores structural integrity, and stops root ingress. Because no driveways, patios, or floors need digging up, it reduces repair costs and project timescales significantly.
Can tree roots be removed from underground pipes without digging them up?
Yes. We use specialist high-speed mechanical milling units (such as Picote Maxi Miller cutters) and specialised root-cutting jetting nozzles to slice out dense root masses inside the pipe bore. Once the line is clear, we install a structural no-dig patch repair over the joint where the roots entered, preventing them from growing back.
Why is a CCTV drain survey recommended when buying a house in the North East?
Standard RICS homebuyer building surveys do not inspect underground pipework. Across Wearside, County Durham, and Tyneside, historic coal mining subsidence and aged Victorian salt-glazed clay pipes frequently exhibit hidden fractures, displaced joints, or pitch-fibre de-rounding. A WRc-standard CCTV survey identifies these expensive defects before contracts are exchanged.
Can you remove set concrete or mortar dropped into drains by builders?
Yes. Hardened concrete, grout, and mortar cannot be dissolved with chemical cleaners or shifted with standard rods. We utilise specialist mechanical grinding flails and ultra-high-pressure jetting heads to precisely pulverise the concrete blockage without fracturing the host clay or uPVC pipe.
How quickly can your emergency drainage team reach Newcastle or Middlesbrough?
Operating directly from our Sunderland hub (SR5) with rapid access to the A19 and A1(M) corridors, our emergency response vans typically arrive on site across Newcastle, Gateshead, Washington, Chester-le-Street, or Middlesbrough within 60 to 90 minutes for urgent flooding or foul backups.
