Rapid-Cure Membrane Makes Quick Work of Bridge Repair

This article describes a case study of a methyl methacrylate-based (MMA)waterproofing system used to rapidly repair one of the Port of Brisbane's major motorway bridges. The Port of Brisbane, Motorway Link Road Bridge, owned by Queensland Main Roads, is 1 of 14 structures constructed in 2002 as part of a motorway constructed to improve transport along the east coast of Australia. The three years old bridge required urgent refurbishmant following a major diesel spillage which permanently damaged the asphalt surface. During the removal of the surfacing, a greater depth of concrete was inadvertently milled off, leaving a low cover over the reinforcing bars, and it was vital for this area to be quickly and effectively protected to prevent water and chloride ion penetration. Eliminator two-component, rapid curing liquid spray applied waterproofing system, in conjunction with the high performance Bond Coat SA 1030 was identified to solve the problem. In order to minimize disruption to traffic, the work was scheduled for a weekend closure. The system was applied to the exposed concrete deck, and the bridge was ready to be re-opened on the following Monday morning.
