Drainage Services Dulwich
Blocked drain clearance, CCTV surveys and no-dig relining for Dulwich homes, from engineers who know Dulwich buildings.
Local knowledge
Dulwich housing, from a drainage engineer's side
Dulwich is characterised by substantial Victorian and Edwardian villas and larger terraced homes, often set within generous plots with mature, established gardens. The drainage systems are typically older, long-run clay pipes that traverse significant distances from property to sewer. The extensive tree and shrub root systems from private gardens are a major factor, alongside the potential for pipe degradation across these long, private lateral runs. Property transactions here frequently require detailed drainage due diligence.

What fails here
Common drainage problems in Dulwich
01
Long Private Lateral Defects
The extended private drain runs from house to sewer are vulnerable to multiple points of failure over their length, including sagging, backfall, and root intrusion. A full-length CCTV survey is critical to create a complete defect map, identifying specific grades of issues like deformation or displacement that affect flow.
02
Garden Root Intrusion
Root systems from large private trees and shrubs aggressively seek out drainage pipes, causing infiltrations that are often deeper within the property boundary. Our surveys classify the root severity (e.g., light, medium, heavy) and pinpoint the exact joint or crack of entry, informing targeted root cutting or relining solutions.
03
Pre-Purchase Drainage Surveys
Conveyancers and prospective homeowners for these high-value properties routinely require definitive drainage condition reports. We provide comprehensive CCTV documentation with WRc-style defect coding, highlighting issues like existing fractures or partial blockages that could entail significant future liability.
04
Partial Blockages in Low-Use Drains
Secondary drains or those serving less frequently used facilities in large homes can suffer from slow-draining partial blockages that go unnoticed. Thermal and zoom CCTV capabilities allow us to diagnose these subtle flow restrictions and sediment build-ups before they cause a total failure.
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.
