In January 2008 this Rocla PermaTrak concrete boardwalk system survived a major bushfire, which engulfed the boardwalk in a native vegetation reserve at Comet Bay, Western Australia. The boardwalk survived the fire completely unscathed.
Landscape architect Stuart Pullyblank of Urbis Landscape Architects says the concrete system was specified for its permanence and low maintenance, as well as its imperviousness to fire and termites. The 120-metre boardwalk is made up of precast reinforced-concrete components, including two-metre treads on two-metre bearers, supported by precast stumps and risers.
