Drainage Services Brentford
Blocked drain clearance, CCTV surveys and no-dig relining for Brentford homes, from engineers who know Brentford buildings.
Local knowledge
Brentford housing, from a drainage engineer's side
Brentford presents a stark contrast between its historic core of workers' cottages and the modern, high-density residential blocks along the waterside. This creates a drainage environment where ageing, shallow brick-built or clay systems intersect with new plastic and composite materials in the developments. The proximity to the Thames and historical industrial land use adds factors of high water tables and potential ground contamination.

What fails here
Common drainage problems in Brentford
01
Differential Settlement in New Builds
Modern waterside blocks built on made ground or former industrial sites can experience differential settlement. This stresses drainage connections and can cause misalignment between property drains and the main sewer, leading to leaks and blockages. CCTV surveys monitor for changing deflection at joints.
02
Brick Sewer Degradation
The historic core of Brentford may still utilise sections of original brick sewer. These structures are vulnerable to mortar loss, brick spalling, and infiltration from the high water table. Our CCTV inspections document the condition of these assets using specific defect codes for historical masonry.
03
Interface Blockages at Connections
The connection points between old private clay drains from cottages and modern public or new development sewer systems are common failure points. Material incompatibility and level discrepancies can cause repeated blockages. We diagnose these interface issues to specify correct adaptors and re-lining solutions.
04
High Groundwater Infiltration
Proximity to the River Thames means a naturally high water table. This pressurises groundwater into drainage systems through any crack or defective joint, overwhelming the capacity and causing pumping stations to run constantly. Our surveys help locate and seal major infiltration points.
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.

The proximity to the Thames and historical industrial land use adds factors of high water tables and potential ground contamination.
