Drainage Services Welling
Blocked drain clearance, CCTV surveys and no-dig relining for Welling homes, from engineers who know Welling buildings.
Local knowledge
Welling housing, from a drainage engineer's side
Welling is dominated by post-war housing, including many 1950s and 1960s-built family homes with modesty-sized but well-established gardens. The construction era means clay drains are slightly newer but still prone to age-related failure. Properties often have added conservatories or side-return extensions, placing pressure on original drainage layouts laid before these modifications.

What fails here
Common drainage problems in Welling
01
Drain Runs Under Conservatory Floors
Conservatories added decades later are frequently built over drainage runs. A failure here would traditionally require lifting the conservatory floor. We can remotely inspect and reline the affected section from an external manhole, leaving the floor structure intact.
02
Offset Drain Connections
Later bathroom or kitchen additions often connect to the old clay main drain via an offset junction, which can be a point of blockage and leakage. Excavating to replace the junction is complex. We use internal patch repair to seal the junction area and create a smooth transition.
03
Surface Root Damage from Shrubs
Established shrubbery and hedging in Welling's gardens have dense, shallow root mats that can exert pressure on upper sections of drainage pipes. Clearing these roots and repairing the pipe via excavation would destroy the shrubs. Our no-dig process clears roots internally and seals the pipe against regrowth.
04
Compacted Subsoil Under Drives
Post-war construction often used less ideal backfill material. Over decades, this subsoil under drives compacts and shifts, stressing clay pipes. Relining internally creates a flexible, jointless new pipe that can accommodate minor ground movement without failing.
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.
