Who we are

About Mainmark

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.

Industry Leaders Since 1989

Mainmark has led the industry for re-levelling, ground improvement and void-filling solutions, developing and delivering the world’s most advanced and accurate solutions.

As a global ground engineering and asset preservation company, we draw on over three decades of experience and knowledge in leading, developing and delivering the most advanced and accurate ground improvement, re-levelling and void-filling solutions across residential, commercial, infrastructure and mining sectors.

With over 82,000 completed projects across Australia, New Zealand, Japan, Thailand and the United Kingdom, we have built a global reputation for delivering innovative solutions to some of the most iconic projects in the world, earning international recognition as an award-winning ground engineering organisation.
