Drainage Services Mitcham
Blocked drain clearance, CCTV surveys and no-dig relining for Mitcham homes, from engineers who know Mitcham buildings.
Local knowledge
Mitcham housing, from a drainage engineer's side
Mitcham presents a mix of interwar terraced housing and some earlier Edwardian terraces, generally on more compact plots. Drainage systems are often simpler in layout but share the borough-wide reliance on original clay pipework. A notable feature is the prevalence of shared drainage lines serving rows of terraced properties, where responsibility and defect location can be ambiguous. Ground conditions in parts of Mitcham can contribute to differential settlement, exacerbating drain fractures.

What fails here
Common drainage problems in Mitcham
01
Shared Drain Line Defects
Rows of terraced houses frequently share a single clay drain run to the sewer. A defect in this shared section, such as a fracture or root blockage, impacts multiple properties. Precise CCTV survey documentation is critical to establish the exact location and nature of the defect for apportioning repair responsibility.
02
Boundary and Access Constraints
Limited rear access and narrow side passages in terraced layouts restrict excavation and repair options. This makes non-invasive drain lining a frequent recommendation, but only after a thorough CCTV survey confirms the defect is suitable for such remediation and maps any service conflicts.
03
Ground Movement-Induced Fractures
Variable ground conditions in some areas lead to seasonal heave and settlement. This movement stresses rigid clay drains, causing regular, patterned fractures at specific points like bends or changes in direction, which our surveys classify using WRc codes for accurate repair planning.
04
Combined System Overload
Many original systems combined surface and foul water drainage. Increased hardstanding and roof drainage connected to these aged clay pipes can lead to hydraulic overload during heavy rain, exacerbating joint failure and soil wash-in, visible as sediment deposits on CCTV.
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.
