Christchurch’s earthquakes showed just how vulnerable New Zealand’s buildings are to natural disasters and the need for seismic retrofitting. Our team strengthens existing structures so that they can withstand earthquakes. Additionally, we protect your building from hurricanes, tornadoes, and severe winds from thunderstorms.


Large Scale Experience
