Our history
Mainmark Australia
The pioneers of Resin Injection technology in Australia.
Founded In 1989 by Philip Mack following the earthquake that affected Newcastle, Mainmark quickly established itself as a local industry leader in tailored earthquake repair and remediation solutions. When the work in Newcastle concluded, the company ventured into new territory and began using our specialist grouting techniques elsewhere. This proved to be a catalyst for the future of Mainmark.
Since then, Mainmark has diversified and expanded to offer specialised above and below-ground engineering and remedial services.
Philip’s commitment to excellence and family values never changed, and these qualities drove Mainmark’s growth spanning over 30 years. He believed in getting the job right the first time, with careful planning to ensure the structure was correctly understood and remediated. This same ethos continues today and into the future.
