Drainage Services Isleworth

Local knowledge
Isleworth housing, from a drainage engineer's side
Isleworth combines riverside properties, historic cores with older homes, and 20th-century suburban streets. The proximity to the Thames means some areas have very high water tables. Drainage systems are therefore a patchwork, with some older properties having robust but aged systems, and others experiencing pressure from both groundwater and modern usage demands.

What fails here
Common drainage problems in Isleworth
01
Riverside Property Backflow Concerns
During very high Thames tides or heavy rainfall, the combined sewer system pressure can increase, risking backflow through low-lying drainage points. We install and maintain non-return valves to prevent this, which can become fouled or fail over time.
02
Fractured Pipes from Subsidence
Variable ground conditions near the river can contribute to subsidence or ground movement. This can fracture drainage pipes, especially at rigid clay joints, leading to leaks that wash away soil and cause further settling, as well as blockages from ingress of earth.
03
Blocked Storm Drain Integration Points
Many homes have surface water drains that tie into the main foul system. Leaves, moss, and garden debris easily block these integration points, especially in autumn, causing rainwater to back up and flood patios or driveways instead of draining away.
04
Corroded Cast Iron Downpipe Connections
Older properties often have cast iron rainwater downpipes that feed into the drainage system. These can corrode and break at the connection underground, allowing soil and roots into the system and creating a hidden blockage point.
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.
