Drainage Services Edgware
Blocked drain clearance, CCTV surveys and no-dig relining for Edgware homes, from engineers who know Edgware buildings.
Local knowledge
Edgware housing, from a drainage engineer's side
Edgware is characterised by extensive 1930s semi-detached housing estates, often with consistent architectural styles. These properties typically have separate surface water and foul water systems, but both are constructed from the era's clay or concrete pipes. The uniformity of development means drainage issues can be widespread across entire streets, often relating to the original construction methods and materials.
Engineer's note
For Edgware's estate properties, our systematic CCTV documentation helps establish patterns of defect, which is critical for managing drainage assets across multiple similar homes.

What fails here
Common drainage problems in Edgware
01
System Separation & Misconnections
With separate systems for foul and surface water, misconnections are a common issue, where wastewater is incorrectly routed into storm drains. This causes environmental pollution and blockages. Our CCTV tracing and dye testing definitively identify misconnections, producing a report that satisfies environmental regulator requirements for correction.
02
Joint Failure in Estate Pipework
The clay pipes installed across 1930s estates used mortar joints that degrade over time. This leads to infiltration of groundwater and soil, causing system overload and sinkholes. We document the specific joint failures (WRc Type J defects) along a drain's length, evidencing a systemic issue rather than an isolated fault.
03
Surface Water Drain Overload
Original surface water drains may be undersized for current rainfall intensity or compromised by blockages. This leads to garden flooding and property damp. Our surveys assess the internal condition and flow capacity of these often-neglected drains, providing a technical basis for upgrade plans.
04
Secondary Consolidation Settlement
Long-term settlement of the ground beneath 1930s estates can cause drainage pipes to sag, creating bellies where waste collects. These deformations are a major cause of recurrent blockages. Our engineers use laser profiling in CCTV surveys to measure pipe gradient and pinpoint depression points with millimetre accuracy.
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.
