Black & White Facilities / Service brief
Drain Repairs and Relining
When a survey has found a crack, a displaced joint, root ingress or a leak, the next question is which repair method suits the run and the site. Describe the defect, the run it sits in, how it can be reached and whether the building must stay in use or surfaces protected during the repair. Reported symptoms guide the scope but do not settle the method.
Overview
A liner can only follow a route sound enough to take it. A collapsed pipe, heavy deformation, incorrect falls or a section nobody can reach needs a different answer.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.
What the work can include
The scope can take in a local repair, section renewal or a relining assessment, each tied to the recorded defect and the accessible route. It identifies the section to be repaired, the method chosen, any defect that will remain and what is supplied or tested at sign-off. Other repairs, specialist design, testing or wholesale replacement are excluded unless expressly included.
The handover gives the client the repaired section, the method used and a note of residual defects, with any limitation, interface and follow-on action recorded alongside.
Examples delivered by Property Services
This example was delivered by the separate Black & White Property Services business. A veterinary tub table was draining slowly and backing up because its waste outlet was too high. Black & White Property Services rerouted the waste connection at a lower level to provide the necessary fall. Testing recorded free-flowing drainage without further leakage or backing up. Tub-table drainage repair at a Gateshead veterinary site.
Important decisions
Once the defect is located, the choice is between lining, local repair and replacing the section, weighed on durability, access and cost. That choice must fit the site's operating constraints and the client's route for approving spend.
Before we visit
Before the repair is arranged, provide the CCTV or inspection findings, drainage plans, access details, ownership boundaries, constraints on surfaces above and the service continuity the building requires. On an estate, identify each site and hold consistent asset or area references so one installation's findings stay separate from another's.
Send the finding that prompted the repair, where the run is, what sits above it and who authorises access. State how long the drain can be out of use so options are compared on that basis.
How the work proceeds
The defect is confirmed, repair options compared, access and isolation agreed, the chosen remedy carried out and the repaired section recorded. The handover lets the facilities manager decide what to do about any defect that remains.
What affects cost and timing
Scope and price turn on defect extent, how the run is reached, preparation, surface reinstatement, managing flow during the work and whether digging can be avoided. On a managed site or estate, the operating window, access contact and shutdown limits shape the programme.
Sector and property applications
Offices, schools, shops and industrial premises each place their own demands on surface protection, flow management and repair access. The sector directory shows how those demands differ by type of site.
Local coverage
Coverage extends across Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. Across an estate, record the repaired section, method and residual defects per site. All locations.
Frequently asked questions
When is relining an option?
Where the run is sound enough to take a liner, can be reached and stays on its existing route. A collapse, heavy deformation, poor falls or an obstruction rules it out in favour of another repair or replacement. For an estate programme, track the repaired section, method and residual defects per site so the next instruction is clear.
Does every crack mean the pipe has to be replaced?
No. Defect extent, the condition of the surrounding pipe, access and the service the run must provide decide whether a local repair, liner or replacement is assessed. Where occupants or operations will be disturbed, settle access, shutdowns and retained-contractor interfaces before the date is fixed.
Does a liner alter the route of the drain?
It does not. A liner sits inside the pipe already there; it cannot move a badly laid drain or open a new discharge route. The completion record should state what was done, what could not be completed and what follow-up remains.
What does a repair scope need from the client?
The inspection or CCTV findings, the run's location, access, ownership, constraints on surfaces above and the service continuity required. With those, the repair option can be set against replacement like for like. On planned work, the finding decides whether further repair or relining is scheduled.
Knowledge and guidance
The guides on when a drain can be relined and what a CCTV survey involves set out how to weigh a liner against a local repair or replacement once the defect is known. The service assessment applies that to the building or estate with operating duty, access and approval route in view.
