Drainage in Reigate and Banstead

Reigate and Banstead's chalk-escarpment geology means drainage runs are often laid into ground that drains quickly on the hill faces but becomes clay-bound in the lower valleys around Redhill and Horley – a contrast that produces very different failure modes across the borough. In the Victorian and Edwardian terracing of central Reigate and Redhill (RH1, RH2), original clay-jointed pipes are the norm: roots enter at spigot joints, and the very hard Affinity Water supply deposits calcite that narrows bore and accelerates blockage. Post-war stock in Horley (RH6) typically runs 4-inch PVCu, where the common defect is joint separation from ground movement rather than root ingress.

Every project begins with a CCTV push-rod survey to map exactly what is underground before any work is planned. High-pressure jetting clears blockages and removes scale deposits. Where the pipe fabric is sound but joints have failed, no-dig CIPP relining restores full flow without disruption to driveways or gardens. Where collapse or severe root damage is confirmed, targeted open excavation follows. There is no callout fee; price is fixed after the survey. See /pricing.
