Drainage Services Sidcup
Blocked drain clearance, CCTV surveys and no-dig relining for Sidcup homes, from engineers who know Sidcup buildings.
Local knowledge
Sidcup housing, from a drainage engineer's side
Sidcup features a mix of substantial interwar detached homes and later post-war developments, often on larger, tree-lined plots. The soil composition and mature landscaping contribute to significant ground movement over time. This movement directly stresses the rigid clay drainage networks, making joint displacement and longitudinal cracking prevalent. The property values and transaction frequency here mean drainage surveys are often a prerequisite for conveyancing, demanding high-definition evidential documentation.

What fails here
Common drainage problems in Sidcup
01
Ground Movement-Induced Fractures
Clay soil shrinkage and swell, combined with tree root activity, causes ground movement that stresses rigid pipes. This commonly results in longitudinal fractures or shear-type cracks at pipe joints. CCTV analysis differentiates these from other crack types to inform on the underlying cause.
02
Failing Interproperty Drainage Runs
Larger plots often have shared or complex drainage runs serving multiple outbuildings or former kitchen extensions. These secondary runs, also in clay, are frequently neglected and suffer from collapse. Tracing and diagnosing these ancillary systems is a key part of a comprehensive survey.
03
Blocked Gully and Yard Drain Connections
Surface water systems from drives and patios connect to the main foul drain via gullies. These connections are prone to blockage from debris and root ingress, causing backing-up. Our survey traces the connection point to diagnose whether the issue is isolated or indicative of main drain failure.
04
Degraded Sealed Joints
The original tarred gasket or mortar seals between clay pipe sections have a finite lifespan. In Sidcup, we frequently document joint seals that have completely perished, leading to significant infiltration (inflow of groundwater) which overloads the system during heavy rainfall.
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.
