Drainage Services Purley
Blocked drain clearance, CCTV surveys and no-dig relining for Purley homes, from engineers who know Purley buildings.
Local knowledge
Purley housing, from a drainage engineer's side
Purley is characterised predominantly by 1930s semi-detached homes with larger gardens and mature tree planting. The drainage infrastructure typically consists of clay pipes running at considerable depth to the rear of long plots. These long, private drain runs are vulnerable to intermediate defects that are not evident at the property access point. The soil conditions and tree root systems here necessitate a thorough diagnostic approach.

What fails here
Common drainage problems in Purley
01
Long-Run Root Infiltration
The extensive private drain runs to the rear of 1930s semis pass near mature trees. Roots can infiltrate at multiple points along the pipe's length. A full-length CCTV survey is required to map all ingress points accurately, as partial clearing often leads to rapid recurrence.
02
Deep Drain Access Challenges
Deep-laid drains in long gardens can be difficult to access for investigation. Our procedural methodology uses high-resolution crawler cameras capable of traversing long distances to locate defects without extensive excavation, minimising garden disruption.
03
Sectional Collapse in Rear Gardens
Ground movement from tree root growth or seasonal changes can cause sectional collapse in the middle of long garden drains. Symptoms are often subtle. CCTV pinpointing is essential to avoid unnecessary excavation and to plan a targeted repair, such as patch lining.
04
Illegal Cross-Connections
Historical extensions or outbuildings may have created unauthorised connections, such as surface water into foul drains. This leads to overload and blockages. Our surveys trace all connections, providing documented evidence critical for resolving liability disputes between neighbours.
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.
