Griptec®: stronger connections for seismic resilience

Griptec® mechanical couplers offer a faster, stronger alternative to traditional reinforcement joints, helping New Zealand contractors build safer, more resilient structures in seismic risk zones 

Why does seismic resilience matter in New Zealand? New Zealand’s history with earthquakes has shown how vital it is to build structures that can withstand seismic activity. Every connection in reinforced concrete plays a role in the strength of a building. If those joints fail, the structure is at risk.  

Global credibility, trusted locally  

Griptec® mechanical couplers, developed by Dextra, are used in major projects worldwide – from Jeddah Tower to Brisbane Airport. Their proven performance in high-risk seismic zones makes them a trusted choice for contractors, engineers and builders in New Zealand.  

How Griptec® works  

Instead of relying on long overlaps of reinforcing steel, Griptec® creates a direct steel-to-steel connection. This reduces reliance on the surrounding concrete, which can crack under seismic stress. The result is a safer, more reliable joint that holds strong even during repeated earthquakes.  

Benefits on site  

Griptec® couplers offer practical advantages that make a difference both in design and on site. 

Building safer structures for the future  

Seismic resilience is about more than meeting building codes – it is about protecting communities and ensuring structures remain safe when earthquakes strike. Griptec® gives New Zealand’s construction industry a proven, globally recognised solution to deliver safer, faster and more sustainable outcomes.   

Benefits include: 

• Resilience under stress: tested to perform under cyclic loading, maintaining strength through multiple seismic events.  

• Speed and efficiency: installation takes only 30-45 seconds per bar end, helping projects move faster.  

• Space saving: reduces congestion in heavily reinforced areas, simplifying construction.  

• Compliance: designed and tested to meet stringent international and New Zealand seismic standards.  

• Sustainability: requires less steel than traditional lap splicing, lowering material use and reducing carbon footprint.  

Griptec® is available in New Zealand exclusively through Fletcher Reinforcing. For enquiries or support, please contact the team directly here.
