Drainage Services Clapham
Blocked drain clearance, CCTV surveys and no-dig relining for Clapham homes, from engineers who know Clapham buildings.
Local knowledge
Clapham housing, from a drainage engineer's side
Clapham features substantial Victorian and Georgian terraced housing, with a high proportion of basement conversions and extensive garden landscaping. The drainage infrastructure is often original, with long, shared clay runs serving entire terraces. Large, mature gardens contribute to significant root systems seeking moisture, while basement drainage pumps and added bathrooms increase the hydraulic load on these historic systems. The area's affluence drives property transactions where drainage due diligence is critical.

What fails here
Common drainage problems in Clapham
01
Basement Conversion Drainage Failures
Retrofitted basement bathrooms and kitchens rely on pumping systems that discharge into old clay drains, causing surcharge and blockages. CCTV inspection verifies pump connection integrity and downstream capacity.
02
Garden Root Invasion to Private Drains
Extensive landscaping and mature trees in private gardens cause root intrusion into drainage runs before they reach the public sewer. Our surveys precisely locate the intrusion on the private side, defining the homeowner's responsibility.
03
Surcharging from Hydraulic Overload
Multiple en-suite additions in large family homes exceed the design capacity of original Victorian drains. CCTV evidence documents flow rates and surcharge points, informing necessary pipe upsizing or flow management solutions.
04
Pre-Purchase Drainage Surveys
The high volume of property transactions necessitates comprehensive pre-purchase CCTV drainage surveys. Our reports detail WRc-coded defects, providing conveyancers and buyers with a clear risk assessment for negotiation.
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.
