About South Industries



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.


Present Day

Today, Monolithic™ Domes have been built in almost every state in the U.S., and in more than 30 countries, worldwide. All three brothers and their individual companies: Monolithic Dome Institute (David), Dome Technology (Barry), and South Industries (Randy), continue to work together on many projects, cooperatively and competitively. South Industries continues today in strong family tradition. The corporation is now owned by Randy and his five sons, Andrew, Derek, Josh, Nathan, and Jonathan. They value themselves as a family-oriented company.
