Fastbrick Wall System Testing

Over the past few months FBR has engaged Curtin University, Newcastle University, the Sydney
CSIRO and a host of independent certifiers to conduct extensive testing on the current Hadrian
optimised block prototype, adhesive and render that make up the Fastbrick Wall System.

After conducting 7-day and 28-day compression strength tests, an independent certifier has
determined that the current prototype Hadrian optimised blocks to be used in Factory Acceptance
Testing (‘FAT’) and Build1 meet the requirements for use in up to 3-storey construction. Newcastle
University also carried out bond wrench testing (designed to test the strength of the joins between
the blocks) and prism compression testing on the Fastbrick Wall System, with both completed
successfully. Preliminary flexural testing using the current prototype Hadrian optimised block
indicated that the Fastbrick Wall System is capable of handling the worst cyclonic conditions in
Australia.

The Fastbrick Wall System has also completed fire rating testing at CSIRO Sydney with exceptional
results. FBR intented to test the Fastbrick Wall System until destruction, but the below image shows
the current prototype Fastbrick Wall System after over four hours of fire rating testing, at which point
the test was concluded due to surpassing industry standard testing by a significant margin.

Likewise, thermal rating testing was carried out both internally and at Newcastle University with good
results. A porosity rating test to determine the level of moisture ingress in the Fastbrick Wall System
was completed on a double rendered wall using the current prototype Hadrian optimised block and
adhesive at Newcastle University, producing exceptional results.
