Drainage Services Woolwich
Blocked drain clearance, CCTV surveys and no-dig relining for Woolwich homes, from engineers who know Woolwich buildings.
Local knowledge
Woolwich housing, from a drainage engineer's side
A mix of dense Victorian and Edwardian terraces, large post-war council estates, and new-build developments from the regeneration. Drainage systems are often a patchwork, with estate-era plastic pipes grafted onto older clay networks. Many properties have long, shared lateral drains running under communal estate pathways and green spaces before reaching the main sewer. The redevelopment has also led to modified ground conditions that can stress existing pipes.
Engineer's note
CIPP relining allows us to repair long, collapsed lateral drains under estates without digging up pathways and communal areas.

What fails here
Common drainage problems in Woolwich
01
Estate-Wide Lateral Drain Collapse
The long, shared lateral drains serving post-war estate blocks are prone to full-bore collapse, especially under green spaces and car parks. This can sever drainage for entire blocks, but excavation would be massively disruptive to the estate landscape.
02
Regeneration Ground Movement
Vibration and ground settlement from nearby construction can fracture the older clay pipes serving the terraced houses and estates. This leads to multiple, scattered blockages and leaks that appear simultaneously across a network.
03
Fatberg Formation in Shared Stacks
In high-density estates, multiple waste stacks from flats converge into a single underground pipe. Grease, wipes, and debris combine to form severe blockages (fatbergs) at these convergence points, deep within the system.
04
Damaged Inspection Chambers
Old brick or concrete inspection chambers on estates are often cracked and collapsing, allowing soil ingress that blocks the downstream pipe. The chambers themselves are frequently buried under tarmac or landscaping.
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.
