Local knowledge
Blackheath housing, from a drainage engineer's side
Blackheath is dominated by substantial Victorian and Georgian villas, many subdivided into flats, alongside large period houses. Drainage systems are often original, complex, and extensive, serving multiple occupancy units within a single large property. The prevalence of mature trees and expansive gardens presents significant root challenges, while the high property values necessitate meticulous documentation.

What fails here
Common drainage problems in Blackheath
01
Multi-Unit Drainage Responsibility Mapping
Large houses converted into several flats often have a single, complex drainage network with shared and private sections. Determining responsibility for blockages requires precise tracing. We produce detailed drainage layout diagrams from our CCTV surveys, clearly demarcating sections, which is essential for leasehold agreements and dispute resolution.
02
Deep-Lay Root Intrusion in Large Gardens
Significant tree root systems can penetrate deep-layer clay drains several metres from the tree itself. These intrusions are often severe and cause major pipe deformation. Our surveys document the root type and extent of pipe damage, providing evidence for tree management discussions and specifying the required pipe replacement class.
03
Original Lead or Iron Connector Failure
Period properties may retain original lead or cast iron connectors between soil stacks and underground drains. These can corrode or fracture, causing leaks within the building fabric. Internal and external CCTV inspection isolates these often-concealed failures, enabling targeted repairs that preserve historic fabric.
04
Inadequate Ventilation in Converted Stacks
Subdividing properties can alter the original ventilation of soil and waste stacks, leading to poor waste transport and siphonage of traps. We assess the entire above-ground and below-ground system to diagnose ventilation defects, providing a system-wide report for remediation by a building services engineer.
