Who we are

In 2013, following a 6.6 magnitude earthquake that rocked Marlborough, New Zealand’s premier wine making region, ONGUARD’s Founder and Managing Director, Will Lomax, stood alongside a winery owner as thousands of litres of valuable, hard-earned product disappeared down the drain because of damage inflicted to the tanks.

This led to the creation of a game-changing engineering solution. ONGUARD is the first genuine seismic tank system specifically designed to protect liquid storage tanks and their contents from earthquake damage and loss.

Engineering & Design Expertise

ONGUARD was created in Christchurch, New Zealand, a city that already had a reputation for producing some of the world’s finest structural designers and earthquake engineering techniques. This capability was further enhanced by the need to regroup and rebuild following the city’s own devastating earthquake in 2011.

The Onguard Experts

Behind ONGUARD’s innovative seismic technology lies a very capable and experienced team of structural engineers and designers with a reputation for thinking outside the box. By combining the very latest design tools and methods with our customary innovative thinking, we consistently provide our clients with exceptional results.
