Drainage Services Holloway
Blocked drain clearance, CCTV surveys and no-dig relining for Holloway homes, from engineers who know Holloway buildings.
Local knowledge
Holloway housing, from a drainage engineer's side
Holloway features more varied housing stock, including substantial Victorian terraces and larger Edwardian conversions, often into Houses in Multiple Occupation (HMOs) with extensive basement accommodation. The drainage infrastructure reflects this intensive use pattern, with older, smaller diameter pipes struggling with high-volume waste flows. Systems here may show evidence of past ad-hoc repairs, complicating current diagnosis.

What fails here
Common drainage problems in Holloway
01
HMO Drainage Abuse
High-occupancy HMOs place extreme strain on drainage systems, with a higher incidence of non-flushable items causing deep blockages within the property boundary. Regular CCTV survey programmes are essential for landlords to prove due diligence and manage maintenance costs effectively.
02
Past Substandard Repair Identification
Previous non-compliant patch repairs, such as inadequate patch linings or incorrect pipe segments, create localised flow restrictions and future failure points. Our CCTV surveys meticulously document these defects using standardised terminology for inclusion in landlord repair specifications.
03
Combined System Overflows
During heavy rain, overloaded combined sewers can surcharge back into the lowest points—basement flats. Documenting the capacity limitation of the downstream system via survey is crucial for landlords seeking to install backflow prevention devices justified by technical evidence.
04
Degraded Pitch Fibre Pipes
Mid-20th century repairs sometimes used pitch fibre pipes, which deform and collapse over time, especially under increased load from conversions. Precise CCTV diagnosis differentiates this from other blockages, informing the correct replacement methodology.
Three methods, one visit
High-pressure jetting
Blasts grease, silt and root growth from pipe walls without digging.
CCTV survey
A camera on rods or a crawler unit records the pipe condition end to end.
No-dig relining
A resin liner is cured inside the damaged pipe instead of excavating it.
