Drainage Services Hanwell
Blocked drain clearance, CCTV surveys and no-dig relining for Hanwell homes, from engineers who know Hanwell buildings.
Local knowledge
Hanwell housing, from a drainage engineer's side
Hanwell is dominated by 1930s semis and earlier terraces, often with long rear gardens that slope towards the Brent River. This topography means drainage runs can have inconsistent gradients, promoting silt deposition. The clay pipes are original and surrounded by mature, moisture-seeking tree roots from well-established gardens. The age and layout of the systems here make them prone to gradual degradation rather than sudden failure.

What fails here
Common drainage problems in Hanwell
01
Gradient-Induced Siltation
Drain runs following natural garden slopes may have flat or back-falling sections where original installation standards varied. This leads to chronic silt build-up, requiring regular jetting. A CCTV survey with a distance-measuring wheel confirms gradient issues and silt volume.
02
Garden Root Intrusion
Mature garden trees and shrubs in Hanwell's plots are a significant source of root ingress into clay drains. Roots often enter at the property connection point in the garden. CCTV identifies the specific root type and penetration depth for precise, root-cutting head selection.
03
Joint Seal Failure
The traditional tar or mortar seals in clay pipe joints have degraded over decades. This allows both root hairs and fine soil to infiltrate, causing gradual blockages and undermining pipe stability. Our surveys classify joint defects to WRc standards to determine repair methodology.
04
Pre-Purchase Drainage Assessment
Given the age of the housing stock, informed homeowners often commission a standalone CCTV drainage survey during conveyancing. This provides a full condition report beyond a standard homebuyer's survey, highlighting any latent defects for negotiation or budget planning.
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.
