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

Guten Tag From Germany! ?????? A few weeks ago, Sperra had the privilege of attending the Sustainable and Smart Energy Systems Symposium at Fraunhofer IEE in Kassel, Germany. Jason Cotrell, Lola Vars, and Evan Marquardt joined experts from science, industry, and policy to discuss the challenges and opportunities in advancing resilient, digitalized, and interconnected energy systems. The event provided valuable insights into cutting-edge research and innovations driving the future of energy infrastructure. From sector coupling to resilience strategies, the discussions reinforced the importance of collaboration in shaping smarter and more efficient energy solutions. #EnergyInnovation #SmartEnergySystems #TechnologyLeadership #Sperra

Sperra was proud to attend the California Ports and Offshore Wind Symposium on February 21 in Long Beach. Mason Bell, Jacob Blum, and Sophie Beitel joined the symposium to explore critical conversations around the future of offshore energy, port infrastructure, and workforce development. To close out the day, Alexander Mendez participated in the harbor tour, getting a firsthand look at the Port of Long Beach’s role in supporting offshore energy growth. Thanks to the organizers for bringing together such an impactful event! #OceanEnergy #OffshoreEnergy #AmericanManufacturing #EconomicGrowth

In our latest video, Eduardo Rangel takes us behind the scenes at Sperra to show why setup and cleanup are critical to our 3D concrete printing process. From assembling the mixer components to ensuring every bit of concrete is thoroughly cleared, every detail counts. ???
