Tectonus Seismic Technology

Seismic design is often treated as a compliance exercise, resulting in buildings that are expensive to construct, carbon-intensive, and vulnerable to disruption after a major earthquake. Tectonus develops seismic technology that helps engineers and project teams deliver resilient buildings at lower overall cost. By reducing seismic demand and controlling structural behaviour, our solutions unlock system-level savings across the structure and foundations - without compromising compliance, constructability, or delivery programmes. Trusted globally, Tectonus devices are installed in airports, hospitals, schools, commercial buildings, and other high-value built assets across New Zealand, Japan, the United States, and Canada. Our technology is used in new builds and retrofits, and across timber, steel, and concrete structures. How Tectonus creates value Rather than optimising individual components in isolation, we focus on whole-of-building performance. Reducing seismic demand enables- Lower structural steel and concrete quantities - Smaller foundations and improved buildability - Reduced embodied carbon - More predictable performance during and after seismic events In many cases, these system-level savings more than offset the cost of the devices, delivering a net project saving alongside improved resilience and asset protection. Solutions for engineers Tectonus offers a suite of friction-based seismic solutions selected based on structure type and performance objectives, including: DMAX Brace (alternative to EBFs and BRBs) XBRACE (tension-only systems for lightweight structures) RSFJ Braces and Hold-Downs (damping and recentring solutions) Born from lessons learned after the Christchurch earthquakes, Tectonus combines expert engineering with disciplined manufacturing. With thousands of devices installed globally, we help project teams reduce risk and enable faster recovery after seismic events.
