Drainage Services Colliers Wood
Blocked drain clearance, CCTV surveys and no-dig relining for Colliers Wood homes, from engineers who know Colliers Wood buildings.
Local knowledge
Colliers Wood housing, from a drainage engineer's side
Colliers Wood features dense interwar terraces and several large mansion flat blocks, often with constrained urban plots and limited external space. Drainage systems are compact and often run directly beneath the property's footprint or immediately under narrow front pavements. The high density of housing places concentrated demand on the sewer network. External space for excavation machinery is extremely limited, and any dig would immediately impact public footpaths or critical private access.

Our no-dig approach is designed for constrained urban sites, solving structural drainage problems without the need for large-scale excavation or pavement closures.

What fails here
Common drainage problems in Colliers Wood
01
Collapses Under Building Footprints
With drains running directly under the foundation slab of properties or very close to it, a collapse can lead to structural settlement. This manifests as cracks in interior walls or uneven floors, directly linking drainage failure to building integrity.
02
Public Footway Drain Access
Sections of the lateral drain connecting to the main sewer often run under the public pavement. Obtaining permits for excavation is a lengthy process and causes significant public disruption, with reinstatement costs and obligations.
03
Complete Pipe Occlusion
In such dense settings, problems are often left until a complete blockage occurs. By this point, roots and debris may have fully occluded the pipe, and the hydraulic pressure from upstream may have caused further damage to the compromised clay sections.
04
Limited Access for Machinery
The narrow frontages and lack of driveway space mean traditional excavation with large machinery is often impossible. Even if a dig is planned, it would likely have to be manual, greatly increasing the time, cost, and surface disruption of the repair.
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.
