Drainage Services Erith
Blocked drain clearance, CCTV surveys and no-dig relining for Erith homes, from engineers who know Erith buildings.
Local knowledge
Erith housing, from a drainage engineer's side
Erith presents a varied property stock, including pre-war terraces and significant post-war council-built estates, all with underlying clay drainage. Proximity to the river and historical industrial land use can influence ground conditions. The age and variety of construction periods mean drainage systems can be a patchwork, with some sections having been partially replaced, complicating diagnosis. Surveys here must be thorough to account for these transitions and mixed materials.

What fails here
Common drainage problems in Erith
01
Patchwork Drainage System Defects
Partial historical repairs may have introduced modern plastic pipes connected to old clay systems. These interfaces, or 'connections,' are frequent failure points due to material incompatibility or poor workmanship. Our CCTV surveys meticulously document these transition points for defect classification.
02
Aggressive Root Intrusion from Poplars and Willows
Common moisture-seeking trees in the area, such as poplars and willows, have particularly aggressive root systems. These roots can travel long distances and cause rapid, severe ingress into clay pipes, often requiring more extensive remediation once identified.
03
Corrosion of Old Iron Connections
Where clay drains connect to older soil stacks or downpipes via ironware, severe corrosion of these metal sections is common. This corrosion can collapse into the clay pipe, causing a secondary blockage. The survey must inspect these connection points specifically.
04
Incorrect Falls Due to Settlement
General ground settlement in some areas has altered the gradient (fall) of original drains. Pipes now lying level or back-falling cause constant drainage performance issues. CCTV with laser profiling is used to measure and document these gradient defects accurately.
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.
