Drainage Services Kensington
Blocked drain clearance, CCTV surveys and no-dig relining for Kensington homes, from engineers who know Kensington buildings.
Local knowledge
Kensington housing, from a drainage engineer's side
Kensington is characterised by its grand stucco-fronted terraces and high-value mansion blocks, many with extensive basements. The drainage infrastructure typically comprises deep, shared brick sewer runs serving multiple large properties. These historic systems are prone to complex, interconnected issues where a defect in one lateral can impact several properties, making accurate diagnosis paramount. The scale of these buildings means soil and vent stacks are extensive and critical to diagnose fully.

What fails here
Common drainage problems in Kensington
01
Basement Drainage Surcharging
Deep basements in large terraces sit below the local sewer invert level, relying on pumping systems. Failure or blockage can lead to sewer surcharge and backflow into basement utilities. A comprehensive CCTV survey of both the lateral connection and the internal rising main is essential to diagnose the precise point of failure.
02
Shared Drain Collapse
Long, brick-built shared drains running beneath rear gardens are vulnerable to collapse from root pressure and ground movement. This can sever the drainage service for entire terraces. Our engineers deploy CCTV to map the shared run, identify the collapse's exact location and WRc defect class, and produce a report for all affected freeholders.
03
Vent Pipe Restriction in Mansion Blocks
Blocked or corroded ventilation pipes in tall mansion blocks compromise trap seals, leading to sewer gases and drainage sluggishness. CCTV rod camera inspection of these often-inaccessible vertical stacks is necessary to locate the restriction and provide evidence for a repair mandate.
04
Illegal Connection Identification
Historical property subdivisions can lead to undocumented or non-compliant drainage connections into the main lateral. This can cause overloading and cross-connection issues. We use dye testing and CCTV tracing to map all connections precisely, providing documented drainage layouts for property portfolios.

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.
