LADYWELL BRIDGE, LEWISHAM
The London Borough of Lewisham commissioned Tempo-PCE to waterproof the service trays on a road bridge with acrylic resin injection. Ladywell Bridge, a 150m multi span concrete structure, carries the B236 over the Ravensbourne River and the Mid-Kent rail line. Carrying out the injection from below allowed waterproofing works to be successfully completed while the road bridge remained fully operational, and all services left in place.
Consulting engineers INGealtóir oversaw the structural elements of the works. After an on-site feasibility study and the waterproofing of a trial vault, the full span was waterproofed, achieving approx. 97% reduction of water ingress. In addition, remedial works were completed to arrest concrete spalling and deterioration of girders/beams and soffit, as well as repairs to the exterior brick skin.
