Victorian clay in Thornton Heath and South Norwood. 1920s-1930s vitrified clay across the suburban areas. Modern drainage in Croydon town centre redevelopment zones.
London Clay in the north and centre, transitioning to chalk in the south around Purley and Coulsdon. The River Wandle follows the Clay-Chalk boundary. Different drainage characteristics in the two geological zones.
Common drainage issues include: River Wandle flooding risk affecting drainage in the Wandle corridor; Root infiltration from Wandle Park and Lloyd Park trees; Scale build-up from hard water in Croydon's clay pipe drainage; Shared drainage disputes in Victorian terrace areas of Thornton Heath; Combined sewer issues during heavy rainfall in the Wandle catchment; Joint displacement in 1930s clay drains across the suburban estate areas.
Commercial Property Drain Survey — Croydon Town Centre. Problem: A commercial property investor purchasing a mixed-use Victorian building in central Croydon commissioned a drain survey as part of their due diligence. Solution: Survey revealed the main commercial drain run (200mm vitrified clay) was in fair condition but had a misaligned joint beneath the car park that would need addressing within 3-5 years. The residential drain runs (100mm) had more significant root infiltration requiring immediate treatment. Result: Investor negotiated a price reduction to cover the residential drain remediation. The commercial drain joint is being monitored with a re-survey scheduled for year 2.

The most common causes of blocked drains in London include: grease and fat build-up (fatbergs), root intrusion from London's many mature trees, collapsed or cracked Victorian clay pipes, flushed non-flushable items (wet wipes, cotton products), and ground movement from London Clay shrink-swell. London's Victorian drainage infrastructure is particularly susceptible to root infiltration and joint displacement.
