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 is characterised by its distinctive grid of Victorian stucco terraces, many with original basement areas. The drainage pattern here is heavily influenced by the proximity to the Thames and the historical low-lying nature of the land. Systems often incorporate complex networks of shallow drains and older combined sewer overflows. The high proportion of rental properties and managed apartments means drainage issues can affect multiple tenants rapidly, requiring swift, documented diagnosis.

What fails here
Common drainage problems in Pimlico
01
Basement Drainage Sump Failures
Many Pimlico properties have basement toilets or utility rooms reliant on pumping systems or gravity-fed drains laid at very shallow gradients. These are prone to failure and blockage, leading to basement flooding that requires immediate CCTV investigation to locate the precise obstruction or pump defect.
02
Tidal Backflow in Low-Lying Drains
Proximity to the Thames can, in rare cases of extreme tidal conditions or sewer overload, influence groundwater levels and cause hydraulic backflow into the lowest points of private drainage systems. This is often misdiagnosed as a simple blockage.
03
Degraded Brick Sewer Connections
Many terraces connect to historic brick-built lateral sewers. The mortar can degrade, allowing soil ingress that slowly blocks the pipe or causes subsidence around the connection. CCTV is essential to visually confirm the integrity of this final connection.
04
Grease Blockages in Multi-Occupancy Houses
The high density of houses in multiple occupation (HMOs) and serviced apartments leads to excessive grease discharge from multiple kitchens. This accumulates rapidly in the first few metres of the private drain, forming solid blockages that require mechanical removal.
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.
