Drewstead Road Bridge in Streatham Hill, London, is a vital transport route carrying buses, pedestrians, and heavy vehicles over the main railway line. Originally built in 1968, the bridge required extensive refurbishment to address concrete spalling, chloride ingress, and structural deterioration.
Concrete Repairs Limited (CRL), in collaboration with Free4m Consulting and FM Conway, delivered a large-scale repair programme including hydro-demolition, flowable micro-repair concrete, and an Impressed Current Cathodic Protection (ICCP) system for high-risk crosshead beams. Completed within four and a half months without disruption to the railway or local traffic, the works extend the bridge’s service life by at least 25 years.
