Watch as we fabricate a reinforced concrete cylinder using a combination of 3D concrete printing and shotcrete application. This time-lapse captures the full process—starting with a 3D-printed inner core, followed by shotcrete spraying using a combination of our robot arm and turntable. Innovating new fabrication techniques like this helps us push the boundaries of durable, cost-effective marine infrastructure. #Sperra #3DConcretePrinting #Shotcrete #AdvancedManufacturing #Innovation #Engineering

Our Founder and CEO Jason Cotrell covered serious ground on his trip—three countries, ten cities, and 1,000 miles later, he's officially back home! 🛬 From securing sites in the Middle East and UK to forging key connections with governments, investors, and partners, this trip was a major step forward for Sperra’s global expansion. Oh, and Stonehenge is officially checked off the bucket list! 🏗️✨ Check out Jason’s recap and see what’s next. #GlobalGrowth #Sperra #Expansion #Innovation #Business
🛬 I’m so glad to be headed home!🏡 It’s been a long but productive trip with three countries visited, ~10 cities and ~1000 miles driven. Some of the key outcomes of our trip are: ✔️Confirmation and site selection for setting up shop in the Middle East and UK. 🐪 ✔️Many new connections to government, investors, and friends. ✔️Raised awareness of Sperra products in 3 countries. ✔️Took Stonehenge off the bucket list (3500 BC!!!) 🧙♂️ ✔️Swore I will never buy or rent a BMW 3 Series again for a road tour. 🚔 #offshoresolar #waveenergy #solarenergy #jobs
