Drainage Services Greenford
Blocked drain clearance, CCTV surveys and no-dig relining for Greenford homes, from engineers who know Greenford buildings.
Local knowledge
Greenford housing, from a drainage engineer's side
Greenford is typified by 1930s semis and a notable number of purpose-built maisonettes from the mid-20th century, often set on hillside locations. The original drainage for these properties is predominantly clay, with runs that may traverse significant changes in elevation. This, combined with mature tree cover from street planting schemes, creates specific stress points on the pipework. The maisonettes often have shared drainage stacks and complex internal runs.

What fails here
Common drainage problems in Greenford
01
Pressure Point Cracking
Drain runs on slopes experience varying soil pressure and can settle unevenly. This leads to cracking at specific points, such as bends or where the pipe leaves the building foundation. CCTV inspection pinpoints these high-stress failure points for targeted repair.
02
Stack to Drain Junction Failures
In maisonettes, the junction where the internal soil stack meets the underground clay drain is a critical weakness. Ground movement can fracture this connection, causing leaks at the base of the building. Internal and external CCTV is used to trace and diagnose this specific fault.
03
Surface Water Infiltration
Cracked pipes on gradients can allow groundwater ingress during wet periods, overwhelming the system and causing surcharging at lower inspection chambers. A CCTV survey during dry and wet conditions can diagnose this infiltration, distinguishing it from a primary blockage.
04
Defect Classification for Repair Planning
Given the mix of shared and private drains, repair options range from patching to full replacement. Our surveys classify defects using standardised terminology (e.g., fracture class, joint separation), providing the technical basis for selecting the most cost-effective, long-term solution.
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.
