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 features extensive tracts of 1930s semi-detached housing and some later developments. The consistent housing stock means many properties share similar drainage ages and vulnerabilities. A notable characteristic is the prevalence of shared drainage runs between pairs of semis, where a single fault can affect two households. The clay subsoil common here retains moisture, increasing the risk of ground movement affecting pipe alignment.

What fails here
Common drainage problems in New Malden
01
Shared Drain Disputes and Blockages
It's common for pairs of semis to share a lateral drain to the main sewer. A blockage or collapse in this shared section causes backups in both homes, requiring clear communication and often a shared repair responsibility. We provide clear reports to help neighbours resolve such issues fairly.
02
Ground Movement Fractures
The clay soil expands when wet and contracts in dry spells, causing gradual ground movement. This seasonal shifting can fracture rigid clay pipes, particularly at joints, leading to recurring blockages and underground leaks that may not be immediately apparent.
03
Collapsed Parallell Runs
Many properties have separate but parallel runs for foul and surface water. Age can cause one, often the surface water drain, to collapse first. This can be mistaken for a main sewer issue, but our CCTV surveys quickly identify the specific failed pipe for targeted repair.
04
Sinkhole Risks from Drain Collapse
A complete collapse of a shallow drainage pipe under a lawn or driveway can wash away supporting soil, creating a void that eventually leads to a sinkhole. Early signs include unexplained dips in the garden or sudden settlement of paving slabs.
