Drainage Services Holborn
Blocked drain clearance, CCTV surveys and no-dig relining for Holborn homes, from engineers who know Holborn buildings.
Local knowledge
Holborn housing, from a drainage engineer's side
Holborn presents a mix of historic commercial buildings, converted warehouses, and pockets of Georgian housing, all overlying a dense network of utilities and historic sewer infrastructure. Drainage systems here are often deep, congested, and may have been subject to multiple undocumented modifications during commercial conversions. The proximity to major Thames Water trunk sewers also means that any public sewer issues can quickly impact private systems.
Engineer's note
For commercial property managers and conveyancers, our technical reports de-risk transactions by providing a full audit of often-modified drainage systems in complex buildings.

What fails here
Common drainage problems in Holborn
01
Deep Interceptor Drain Blockages
Many older commercial properties have deep interceptor drains with sealed access points, which trap debris and require specialist equipment to survey and clear. Blockages here can cause building-wide drainage failure. We use extended-range CCTV to navigate these deep interceptors, documenting the condition of the sealed chamber and trap.
02
Utility Conflict Damage
The congested sub-surface space means other utility trenches can have damaged drainage runs during past works. This damage may only manifest years later as ground settles. Our CCTV inspection looks for tell-tale scoring or recent fracture lines indicative of external strike damage.
03
Conversion-Related Pipework Mismatch
Building conversions from industrial to residential or office use often involve incompatible new pipework connected to old drains. This leads to chronic issues like poor flow or leaks at junctions. We audit the entire system to identify material and size mismatches, documenting each non-compliant junction.
04
Public Sewer Back-Pressure Influence
Due to the proximity to major mains, surcharge events in the public combined sewer can force wastewater back into private systems, especially those with low-gradient outfalls. We use CCTV during or after peak flow events to record evidence of back-pressure, such as debris lines on pipe walls, for Thames Water investigations.
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.
