USL Deliver Robust Waterproofing Solution For BAM Nuttall

USL BridgeCare is currently undertaking a complete bridge deck refurbishment to Eccleston and Victoria Bridges outside Victoria Train and Bus Station in London.

Bridge Deck

Eccleston Bridge;

Works are being completed over several phases, Phase 3 has been completed with Phase 2a and 2b underway (phase order has changed).

Following the breaking out of the existing carriageway and footways, temporary and then permanent management solutions had to be implemented to reduce the water finding its way through the holes in the existing deck down onto the platforms below.

Permanent steel plates with mastic sealant were installed followed by concrete screed regulating layer and then painting of various areas of exposed metal.  These works enabled the deck ready for specialist contractor USL BridgeCare to apply their BBA HAPAS PmB two part polyurethane spray applied waterproofing and Aggregated tack coat systems.

Elizabeth Bridge;

Phase 2a was completed and Phase 2b is ongoing. 

Surfacing has been removed from the carriageway and footpath slabs, exposing a concrete deck in fairly good condition that only required minor concrete repairs.
