We Are South Industries
Building the future, grounded in expertise and commitment.
The Monolithic™ Dome was the invention of three brothers: David (Left), Barry (Center), and Randy (Right). These three brothers turned their polyurethane foam spraying company into a concrete dome construction company, after realizing the potential of foam/concrete to build incredibly strong free-span buildings.
Today, South Industries has built domes in almost every state in the U.S., and in countries, around the world. We embrace the family-oriented culture established by the founders of our industry. We extend this culture and courtesy to each of our clients, employees, and stakeholders. We understand that our success is due to the ability to add value to your organization. We transform the construction experience by finishing our projects on time and within budget without fail. Our track record of success allows us to hire and retain the top talent in the industry ensuring that your project exceeds your expectations.
