Loumain Precast Steel Base Construction

The company was founded by Mr. Rob Maroszek. Rob's passion for building and property development are outlined in the core values and principles or what LOUMAIN is today.

1998 - 2000

Rob started as a labourer at his family construction and fitout company in 1996. In 1997 he took on the responsibility for his first refurbishment and fitout of a local pizzeria and in 1998 started contracting as the Maroszek Group. Over the next few years, Rob received exposure to small business operations and construction developments in Poland, Germany and Austria and in the year 2000 he started working in the United States.
From 2000-2008, Rob delivered work to Tier1 companies, such as KB Home and Pulte Homes as well as several smaller projects. His interests and experience expanded to building products manufacturing which included shutters, masonry features and alternative materials used in building and construction. In order to enhance his ability to deliver larger and more complex projects, Rob acquired tertiary education qualifications including a B.S. in Business, Construction Management and later an MBA.

Since then, the company has project managed, constructed and completed fitouts of more than 70 developments ranging in size from $50,000 to over $10M.

The company continues to conservatively grow and expand. Presence was established along Australia's eastern coast in order to meet the needs of Sydney, Brisbane and other hubs, including inland and regional areas.
