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 characterised by its stretches of 1930s semi-detached homes, often with generous gardens, alongside some earlier Edwardian terraces. The area's proximity to the River Brent and its tributaries influences local ground conditions, with some pockets of higher water tables. This can accelerate the degradation of old clay pipes through external erosion and frost damage. The garden sizes mean drainage runs to the main sewer are often lengthy, increasing the potential for multiple points of failure along a single line.

What fails here
Common drainage problems in Hanwell
01
Long Garden Drain Failures
The lengthy drainage runs from the rear of 1930s semis to the main sewer at the front are vulnerable at multiple points. Excavating the entire garden to replace a failed clay pipe is hugely destructive to landscaping, patios, and outbuildings, making a trenchless relining of the entire run from a single access point the preferred solution.
02
High Water Table Erosion
In areas near watercourses, a high water table can saturate the ground around buried clay pipes. Over time, this flowing groundwater can erode the pipe bedding, leading to sagging and eventual collapse. It also accelerates the deterioration of the clay itself, making full-length structural relining more effective than spot repairs.
03
Frost Damage to Shallow Runs
Some original drains in Hanwell's older properties were laid at a relatively shallow depth, particularly where they cross open gardens. In cold winters, frost can penetrate the ground and cause brittle clay pipes to crack or shatter. Repairing these shallow runs with excavation would require digging up large areas of lawn or planting beds.
04
Patio and Decking Obstructions
Many homeowners have installed extensive patios or decking over the rear drainage runs. When a problem occurs under these hard landscapes, the financial and aesthetic cost of breaking them up is high. A no-dig approach allows us to repair or reline the pipe from an upstream manhole, leaving the patio completely undisturbed.
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.
