By undertaking this seismic testing, KOROK® reinforces its commitment to superior building resilience, helping to minimize damage, lower repair costs, and maintain operational continuity after earthquakes.

Importance of Seismic ResilienceSeismic Resource

The 2010/2011 Christchurch earthquakes and the more recent 2013 Lower North Island earthquakes illustrated the vulnerability of building non-structural elements (partitions, building services and piping). Widespread damage and loss of business continuity due to the poor performance of non-structural elements was widely observed

The Canterbury Earthquakes Royal Commission identified the need to improve the performance of non-structural elements in earthquakes with one of the recommendations focussed on improving non-structural element performance. “To prevent or limit the amount of secondary damage, engineers and architects should collaborate to minimise the potential distortion applied to non-structural elements. Particular attention must be paid to prevent the failure of non-structural elements blocking egress routes.”

Proven Seismic Performance

Conducted at BRANZ in 2024, our seismic tests followed FEMA 461 and NZS 1170.5:2004 standards, confirming KOROK® panels has the ability to withstand high levels of drift. No other system in New Zealand has undergone such rigorous testing with multiple wall configurations and variations.

Application in High-Importance Structures

As the ultimate All-in-One solution for fire & acoustic-rated wall systems, KOROK® panels offer unmatched performance for high-importance structures. With strong seismic performance and the ability to withstand high drift limits, KOROK® panels are ideal for IL3 and IL4 buildings, such as hospitals, emergency response centres, and essential utilities.

Our Commitment to Waste Reduction

At KOROK, we focus on reducing waste and being environmentally responsible. Our efficient manufacturing processes and thoughtful product designs help us provide reliable, high-performance solutions.

KOROK’s Sustainability Journey

Reducing Waste

Made to Order

Our panels are manufactured to order, ensuring minimal waste. This custom approach means minimal off-cuts and no unnecessary waste, as each panel is designed to fit specific job requirements perfectly.

Fully Reusable

KOROK panels are designed for reuse. They can be taken down and reassembled multiple times, making them ideal for reconfiguring warehouse or retail spaces. This reusability significantly enhances their ecological friendliness, reducing the need for new materials and minimising waste.

Fully Recyclable

When a KOROK panel reaches the end of its life cycle, it doesn’t need to end up in a landfill. The panels can be disassembled for recycling: the concrete core is crushed and repurposed, and the steel casing is recycled. This closed-loop process ensures that our products contribute to a sustainable future.
