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 encompasses older Victorian/Edwardian terraces near the town centre alongside significant post-war housing developments and estates. This creates a drainage landscape with two distinct ages of infrastructure, but the post-war builds often inherited or extended upon older clay systems. Proximity to the river and marshier ground in parts can also influence drainage behaviour, with ground saturation affecting clay pipe stability.

What fails here
Common drainage problems in Erith
01
Mixed-Age Pipework Transitions
Drainage systems here can be a patchwork, where post-war extensions tie into much older Victorian-era clay or even brick sewer connections. These transitions are weak points, prone to misalignment and collapse, requiring careful tracing to understand the full system.
02
Saturated Ground Collapse
In areas with higher water tables, persistent ground saturation can soften the bedding around clay pipes. This loss of support leads to gradual pipe movement, joint separation, and eventual collapse, exacerbated by the weight of the overlying soil.
03
Blocked Original Stacks
In the post-war low-rise flats and maisonettes, original soil stacks and vertical drainage within the building fabric are often made of cast iron or old clay. These can corrode or crack internally, causing leaks within walls and persistent blockages that are difficult to trace.
04
Post-War Estate System Overload
Some estate drainage systems, designed for lower capacity decades ago, now struggle with modern water usage and increased surface water. This can cause system-wide slow drainage, with individual property issues often being a symptom of a larger, shared network problem.
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.
