Drainage Services New Malden
Blocked drain clearance, CCTV surveys and no-dig relining for New Malden homes, from engineers who know New Malden buildings.
Local knowledge
New Malden housing, from a drainage engineer's side
New Malden presents a blend of inter-war semis and numerous Edwardian terraces, often with smaller rear gardens but significant frontage. Drainage layouts can be less standardised, with adaptations and repairs over the years leading to potential weak points. The area's clay soil composition can expand and contract with moisture, applying cyclical stress to buried drainage pipes and accelerating failure at connection points and bends.
Engineer's note
Our patch repair and spot lining techniques precisely target fractures at connections and legacy junctions without the need for wide, deep excavations in narrow or obstructed spaces.

What fails here
Common drainage problems in New Malden
01
Clay Soil Heave Damage
The reactive clay soil expands when wet and contracts when dry, causing ground movement. This seasonal heave puts stress on rigid clay pipes, leading to fractures, particularly at rigid connections to the house or at bends where stress concentrates.
02
Legacy Patchwork Repairs
Previous partial excavations for repairs may have introduced modern PVC sections connected to old clay pipe with incompatible seals. These junctions are common failure points, prone to leaks and root ingress, creating a need for a uniform, continuous pipe wall.
03
Obstructed Access for Excavation
Narrow side passages and proximity to boundary walls often make mechanical excavation for deep drain repairs impossible. This leaves only manual digging or a no-dig solution as viable options to reach and repair the faulty section.
04
Fractures at Property Connections
The point where the house drain connects to the underground pipe is highly vulnerable. Ground movement and settlement often cause fractures here, leading to leaks near the property foundation, which are problematic to access without disturbing the building's footprint.
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.
