Drainage Services Bank
Blocked drain clearance, CCTV surveys and no-dig relining for Bank homes, from engineers who know Bank buildings.
Local knowledge
Bank housing, from a drainage engineer's side
This area is dominated by historic banking halls and office buildings that have undergone extensive conversion to luxury residential and commercial use. The property profile includes deep basements and sub-basements, which house complex drainage infrastructure often dating back to the Victorian era. Drainage systems here may combine original brick or clay sewers with modern plastic pipework, creating potential for misalignment and joint failures. The high value of these properties makes accurate, non-destructive diagnosis paramount.

What fails here
Common drainage problems in Bank
01
Basement-Level Drainage Backups
Groundwater infiltration and surcharge from the public sewer can overwhelm basement drainage systems, especially during heavy rainfall. Our CCTV surveys can identify inadequate non-return valves or faulty check valves, and diagnose whether a backup originates from the public main or an internal private section.
02
Historic Sewer Integration
Modern conversions often tie new drainage into centuries-old brick or stone sub-basement sewers. These junctions are prone to misalignment, debris accumulation, and collapse. CCTV inspection documents the condition of these historic sections, informing decisions on lining, replacement, or bypass creation.
03
High-Traffic Grease Accumulation
Properties with ground-floor commercial kitchens (e.g., in mixed-use buildings) contribute to severe fat, oil, and grease (FOG) build-up in shared drainage. This requires regular CCTV monitoring to assess FOG levels and the effectiveness of installed grease management systems, providing evidence for compliance.
04
Subsidence and Ground Movement Impact
Proximity to major construction and the Tube network can cause ground movement, stressing old clay pipe joints. Our surveys classify joint displacement (e.g., open joints, fractures) using standardised codes, creating a vital record for structural insurance claims and party wall matters.
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.
