Local knowledge
How Merton drains fail
Merton housing is dominated by Edwardian semis, interwar terraces and mansion flats. The Edwardian and interwar housing stock in this area is often connected to original clay drain runs, which are susceptible to root ingress and fracture given their age and material.
Knowing the local building stock matters: it tells us what pipe material and depth to expect, and which method will clear or diagnose the problem fastest — before we arrive.

Three methods, one visit
High-pressure jetting

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.
Common drainage problems in Merton
Aging Clay Drain Fractures
The original clay drainage systems common in Merton's Edwardian and interwar properties are inherently brittle. Over decades, ground movement and pressure can cause these pipes to crack or collapse entirely. This leads to persistent blockages and requires structural repair, not just clearance.
Root Ingress in Old Sewers
Tree roots are drawn to the moisture and nutrients in the small cracks and pipe joints of historic clay drains. In Merton's mature neighbourhoods, these roots can infiltrate, creating dense, fibrous blockages that worsen over time and eventually compromise the pipe's integrity.
Displaced Joints in Terraced Runs
The long, continuous drain runs serving terraced housing and mansion flats are particularly vulnerable at their collar joints. Ground subsidence or root pressure can displace these connections, creating gaps where soil washes in. This causes repeated blockages and undermines the structural line of the pipe.
Partial Collapse Under Driveways
Access to drains often runs beneath paved driveways and garden paths common to this housing stock. A fracture in a clay pipe can allow surrounding material to erode into the pipe, leading to a partial void and eventual sagging or collapse of the section, which disrupts flow.
