HeliBar starts as round, stainless-steel wire with a typical 0.2-percent proof stress of 500N/mm², but after the cold forming manufacturing process that creates the helical hi-fin design, this more than doubles to around 1100N/mm². This means that HeliBar, with its relatively small diameter, provides substantial tensile properties to the masonry. This is particularly true when combined with HeliBond grout, which locks between the fins and bonds to the masonry.
Rounding out the Helibeam System to help with displacement, about 9,000/10mm DryFix remedial ties were installed through the veneer and into the backup, thus providing lateral restraint and securing the facade.
"The Helibeam System was specified because of its proven ability to secure existing masonry," says Brett Laureys, WJE associate principal. "It is fully concealed (once installed), and its flexibility allows it to be bent around corners with no loss of performance. It was also the most cost-effective stabilization method available and, with all work undertaken externally, there was minimal disruption to the upper floor tenants during this 'emergency restoration phase, which overcame the veneer's lack of support, securing the structure while full renovation of the Olympia Theatre was safely undertaken."
