The United States might be behind in adopting a construction technique that could keep houses intact during natural disasters, including hurricanes, earthquakes, tornadoes, and fires. The building material known as a 3D cementitious sandwich panel was developed by company RSG 3-D and consists of “fire retardant foam sandwiched between two wire mesh faces,” according to CNBC. The faces are then connected with reinforcement wires that run through foam and is enveloped in concrete.
"The RSG 3-D panel is known for it resilience to natural disaster," Calligar said. "The panels are fireproof, they are seismic resistant beyond any earthquake recorded in human history and they are also hurricane resistant. They've been tested throughout the world through 200 hurricanes, hundreds of seismic events and several wildfires."
The technology is not new. NASA has been using a version of it to build spacecraft for years because of its strength. And former President Carter used the material through his charity work for rehabilitation efforts decades ago on damaged buildings in Florida and Georgia.
RSG 3-D is one of a handful of companies using EVG's technology to bring the material to the U.S. for mass production. Higher lumber costs, expensive skilled labor and more demanding building codes are making it an appealing alternative to conventional construction.
