Drainage Services Thornton Heath
Blocked drain clearance, CCTV surveys and no-dig relining for Thornton Heath homes, from engineers who know Thornton Heath buildings.
Local knowledge
Thornton Heath housing, from a drainage engineer's side
This area features a mix of Victorian terraces and inter-war semi-detached housing, often with modest garden sizes. Drainage systems are typically older and may have been subject to past, potentially substandard, repairs. The urban density and age of the infrastructure mean that blockages can have a rapid knock-on effect on neighbouring properties due to the interconnected nature of the networks.

What fails here
Common drainage problems in Thornton Heath
01
Previous Repair Failure
Past point repairs using patch materials or incorrect pipe sections can create new weak points and flow restrictions. Our CCTV surveys assess the integrity of previous work, documenting any new defects that have formed adjacent to old repairs for a complete condition picture.
02
Intrusive Root Networks
Proximity to street trees and boundary hedging means root networks are pervasive. Roots often enter through already compromised joints, exacerbating existing defects. We classify root ingress according to WRc standards, noting whether it is a primary cause or a secondary symptom.
03
Surcharging from System Overload
Increased property occupancy and modern water usage can overload the original drain capacity, leading to frequent surcharging at low points. Diagnostic surveys measure flow and identify hydraulic deficiencies, evidence often needed for planning permission for extensions.
04
Cross-Boundary Drainage Disputes
Unclear drain routes under multiple properties are a common source of dispute. A definitive CCTV survey maps the exact drain path and identifies the location of a blockage, providing impartial technical evidence to resolve conflicts between residents.
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.
