Drainage Services Chelsea
Blocked drain clearance, CCTV surveys and no-dig relining for Chelsea homes, from engineers who know Chelsea buildings.
Local knowledge
Chelsea housing, from a drainage engineer's side
Chelsea features a mix of elegant stucco terraces, modernised mews houses, and luxury riverside apartments. The proximity to the Thames influences high groundwater levels, placing additional hydraulic pressure on drainage infrastructure. Mews conversions often have creatively routed, older drains now servicing modern demands. The high proportion of listed buildings demands non-invasive diagnosis to preserve fabric.

What fails here
Common drainage problems in Chelsea
01
Thames Tideway Back-Pressure
Properties close to the river can experience hydraulic back-pressure from the main sewer network during high tide, causing slow drainage in ground-floor facilities. CCTV surveys timed with tidal cycles can capture this phenomenon, providing clear evidence for the need for non-return valve installation.
02
Mews House Drainage Misalignment
Original drainage in mews houses, now extensively refurbished, often has new bathrooms and kitchens connected to aged, shallow clay runs. This leads to poor falls, silt traps, and repeated blockages. CCTV pinpointing of inadequate gradients is crucial for designing a compliant replacement system.
03
Listed Fabric Investigation
Investigating drainage faults in listed buildings requires minimal excavation. Our CCTV survey provides a definitive internal diagnosis of pipe condition and defect location, enabling targeted, conservation-approved repair methodologies that avoid unnecessary disturbance.
04
Silt Infiltration in Shallow Runs
Shallow drainage runs in mews and terraced gardens are susceptible to silt infiltration from high groundwater, reducing bore capacity. CCTV inspection clearly shows silt levels and entry points, informing a targeted jetting and sealing programme rather than guesswork.
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.
