Blocked drain clearance, CCTV surveys and no-dig relining for New Malden homes, from engineers who know New Malden buildings.
Local knowledge
New Malden housing, from a drainage engineer's side
New Malden presents a notable concentration of Edwardian terraced housing alongside later 20th-century developments. The terraces often have narrower plots but still feature mature tree planting. Drainage systems here are typically older, with a high likelihood of original clay pipework serving multiple properties in sequence.

What fails here
Common drainage problems in New Malden
01
Serial Drainage Blockages in Terraces
Long, shared drainage runs serving rows of Edwardian terraces are susceptible to serial blockages that affect multiple properties. Pinpointing the exact defect location—often a single collapsed section—requires progressive CCTV surveying to isolate the problem and prevent unnecessary excavation on adjacent properties.
02
Limited Excavation Access
The narrower plots and proximity of properties in New Malden's terraced streets restrict access for traditional excavation machinery. This makes accurate pre-repair CCTV surveying even more critical to enable precise, minimally disruptive solutions like patch lining or directional drilling.
03
Age-Related Pipe Degradation
The consistent age of the Edwardian housing stock means widespread, simultaneous ageing of clay drainage infrastructure. Generalised pipe wall degradation, as opposed to isolated fractures, is common. CCTV surveys must assess overall pipe integrity, classifying defects to prioritise sections for repair or replacement.
04
Incorrect Past Repair Materials
Historical DIY or non-specialist repairs may have used inappropriate materials like cement or short-term patches. These often fail and complicate the drainage system. Our CCTV diagnosis identifies these non-standard interventions, and our reports document the need for a compliant, permanent repair.
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.
