Drain Unblocking in Redhill — Local Specialists
Redhill is a Victorian railway town in Surrey, developed rapidly after the arrival of the railway in 1841. Most of the Victorian terraces in the town centre have original clay drain systems dating to the late 19th century. The area sits on Greensand and Gault Clay, which can be impermeable in wet conditions, causing surface water issues in lower-lying parts of the town.
Redhill’s drains are a product of its Victorian railway boom. The town grew at extraordinary speed once the London–Brighton line arrived in 1841, and the terraces around the town centre, the station and towards the former railway works were run up fast with the clay pipes of the day. Those original runs are now well over a century old, and after decades of ground movement their collars have opened up, letting in both the surrounding Gault Clay — which swells and shrinks dramatically as it wets and dries — and the roots of the street trees. On top of the ageing pipework, the underlying Greensand and Gault Clay are famously impermeable once saturated, so in a wet spell the water has nowhere to drain and the lower-lying parts of the town, particularly down towards Earlswood and the valley, suffer from surface water that sits and then works its way into older drains.
The housing stock spans the Victorian terraces of the town centre and the station approach, through inter-war and post-war estates around Merstham and Salfords, to the newer development at Holmethorpe and Whitebushes. Because so many of the Victorian terraces share a rear drain with their neighbours, a blockage on one property quickly backs up the row, and access is often through narrow back gardens. Our engineers clear root and silt-blocked clay runs with high-pressure jetting, use CCTV surveys to locate displaced joints before any digging, and reline or replace failed sections of the original pipework. For the town’s many cafés, restaurants and takeaways along the high street and around the station, we keep grease traps serviced so oil-rich waste stays out of the shared drains.
Because the Gault Clay ground can’t absorb heavy rainfall, the lower-lying streets of Redhill and Earlswood are the ones most at risk of surcharge, so it pays to keep the gully and inspection chamber clear before the autumn. If you are buying one of the Victorian terraces, a CCTV survey before exchange is a sound step — it shows you exactly what the century-old run is like underneath before you take it on.
