Drainage Services Pimlico
Blocked drain clearance, CCTV surveys and no-dig relining for Pimlico homes, from engineers who know Pimlico buildings.
Local knowledge
Pimlico housing, from a drainage engineer's side
Pimlico features distinctive white stucco terraces built on former marshland, with a high proportion of mansion flats in converted Victorian houses. The low-lying geography and complex network of subsurface channels mean groundwater infiltration is a persistent issue. Many properties still have their original brick-built drainage runs and shallow gradients, leading to frequent silt build-up and slow drainage, exacerbated by the area's historical combined sewer system.
Engineer's note

What fails here
Common drainage problems in Pimlico
01
Low-Gradient Siltation
Due to the flat topography, many original drains in Pimlico have very shallow gradients. Waste travels slowly, allowing silt, sand, and debris to settle and compact over time, causing gradual drainage failure that requires regular mechanical clearing to prevent complete blockages.
02
Groundwater Infiltration
The high water table from the former marshland leads to constant groundwater seeping into cracked clay and brick drain runs. This overwhelms the system, causing manholes to constantly fill with clear water and reducing the sewer's capacity for actual waste, requiring sealing or lining.
03
Brick Sewer Collapse
Many properties connect to historic brick-built sewer mains, not just clay laterals. These bricks degrade and can collapse inward, causing major subsidence and drainage failure that demands extensive excavation and reconstruction, not just clearing.
04
Shared Courtyard Drain Failures
The classic Pimlico terrace layout uses shared rear courtyards with a single drain run serving multiple properties. Blockages or collapses in this shared section cause immediate problems for several households, requiring coordinated access and clear responsibility for costs.
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.
