A complete success.
Those words were uttered by Gary Bullock just after sprayed Protectiflex walls were hit with shock loadings similar to a car bomb explosion from a distance of 20 metres.
The Flexiroc Australia managing director had talked up Protectiflex before the product was tested on Tuesday at Australia's only national blast simulation facility, at the University of Wollongong.
The spray-on concrete that is blast, ballistic and fire-resistant, combines recycled crumbed rubber from old tyres with composite fibres in a cementitious mix design.
"We are confident these tests will prove the spray-on composite creates blast resistant walls," he said.
Once the first test was over, Mr Bullock was grinning from ear to ear.
"It's an absolute success. There's only a small crack in the wall and it has only moved 12 millimetres," he said.
Up till now Protectiflex walls have been used in either cast-in-place or precast construction methods.
The spray-on application can be applied to both new and existing walls and buildings to develop or enhance their blast, ballistic and fire-resistance ratings.
Professor Alex Remennikov from the UOW's Faculty of Engineering, shared Mr Bullock's excitement.
"This is the first time in the world this protective solution is being tested," Prof Remennikov said.
"It is developed in Australia. It is being tested in Australia and it will be first in the world application for protecting Australian infrastructure from possible terrorists attacks."
He added the ProtectiFlex blast tests demonstrated how spray-on retrofit could add strength and stiffness to concrete masonry walls, protecting occupants behind it from the blast loads.
"Masonry walls are a common building component that is vulnerable to blast loads created by terrorist attacks or accidental explosions," Prof Remennikov said.
"The blast simulation facility was established to overcome the challenges associated with live explosive testing, such as very high cost, safety, efficiency and repeatability of test result."
Mr Bullock said ProtectiFlex has applications across a range of sectors including defence, government, critical infrastructure, petrochemical and retail.
He added that the product was especially popular in America and the Middle East.
"ProtectiFlex is not only a great way to protect human life and critical assets, it's also lightweight, eco-friendly, cost-effective and incredibly versatile in its form and application," Mr Bullock said.
"Although today's experiment involves testing how the spray-on product handles blasts, we hope to conduct further studies in the future proving it performs just as well in fire, ballistic and weapons tests."
Tyre Stewardship Australia CEO Lina Goodman said "this innovative product made from recycled tyres could potentially save lives".
"Although more than half of Australia's old tyres are recycled, upcycled or processed to make other products, like ProtectiFlex, the equivalent of 27 million car tyres are wasted every year. These often end up in landfill, stockpiles or are exported overseas," she said.
TSA has committed $5 million to a wide range of Australian projects using waste tyres including ProtectiFlex, roads, horse racing tracks, car parks, sports grounds and playgrounds.
