Drainage Services Colliers Wood
Blocked drain clearance, CCTV surveys and no-dig relining for Colliers Wood homes, from engineers who know Colliers Wood buildings.
Local knowledge
Colliers Wood housing, from a drainage engineer's side
Colliers Wood features tight-knit terraces of interwar housing alongside modern flat conversions within older commercial buildings. The density of development means clay drainage runs are often convoluted, passing close to building foundations and under multiple property boundaries. Many homes have combined kitchen and bathroom waste lines feeding into a single, aged clay pipe. The proximity to the Wandle river can influence ground water levels, exacerbating issues with fractured drainage lines.
Engineer's note

What fails here
Common drainage problems in Colliers Wood
01
Combined Waste Line Blockages
With kitchens and bathrooms often on the same narrow clay run, blockages from grease combined with soap scum are frequent and severe, requiring high-pressure jetting to clear the hardened deposits from the old pipes.
02
High Groundwater Infiltration
Proximity to high water tables means any crack in a clay pipe can lead to significant groundwater infiltration, causing the drainage system to constantly fill with silt and water, even when the property is not in use.
03
Convoluted Pipe Runs
The drainage layout in these tight terraces often has multiple bends and junctions as it navigates property boundaries. These sections are prone to debris build-up and are difficult to jet or survey effectively.
04
Structural Damage from Leaking Drains
Leaking clay drains running close to shallow foundations can wash away supporting soil, leading to localised subsidence and cracks in walls, which is a more serious structural issue beyond a simple blockage.
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.
