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
Woolwich is characterised by extensive post-war council estates, interspersed with Victorian terraces and ongoing large-scale regeneration projects introducing new residential blocks. The drainage network is a patchwork of ageing estate systems, some with combined sewers, and modern plastic installations. The scale of redevelopment means existing drains are often exposed to new stresses from adjacent construction activity.

What fails here
Common drainage problems in Woolwich
01
Post-Ware Estate Combined Sewer Overload
Older combined systems in estates can surcharge during heavy rainfall, leading to internal flooding in low-ground-floor properties. Diagnosing whether a backup is due to a downstream blockage or system overload is crucial. Our CCTV surveys include condition assessments of the main estate outfall to provide evidence for utility upgrade requests.
02
Construction-Related Drainage Damage
Ground vibrations and excavation from regeneration projects can fracture brittle post-war pipes or displace joints. Symptoms manifest as sudden blockages or subsidence. We provide timestamped CCTV evidence linking damage to construction phases, which is vital for contractor liability claims.
03
Corroded Cast Iron Stacks
Multi-storey estate blocks often have original cast iron soil stacks internally. These can corrode from the inside, causing localised leaks and reducing bore diameter. Internal CCTV inspection of these stacks identifies corrosion levels and pinpoints leak locations for targeted replacement, avoiding full system renewal.
04
Regeneration Area Connection Mis-matches
New developments connecting to older estate mains can face pipe size or material incompatibility, creating flow restrictions. Our engineers survey both sides of the connection point, documenting the mismatch with precise measurements for the design of compliant adaptors or liners.
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.
