Affordable solutions to repair, seismically strengthen and safeguard your assets
Help buildings withstand seismic risk.
As the experts in earthquake strengthening, we only use the latest strengthening technologies to ensure your property remains protected from nature’s potentially devastating effects.
Plain-English overview
Seismic strengthening & seismic upgrades.
The Connect Group’s internationally trained seismic strengthening specialist team provides tailored solutions to repair, strengthen and protect your assets, and the people within.
With a strong reputation built on innovation and collaboration, our team are specialists in residential, commercial and heritage works, known for their capacity to take on large-scale projects such as the Christchurch Art Gallery and Christchurch Town Hall. The Canterbury Earthquakes taught us that stringent seismic methods are required to safeguard not only the building, but its occupants. For over 20 years, our team has expanded its skillset to strengthen both commercial and residential buildings against seismic activity, managing the entire process from initial project management to final completion. We back that experience with cutting-edge technology, including Hilti advanced core-drilling and anchoring equipment, so the drilling and fixing that strengthening depends on is precise and reliable.
Common use cases
Where seismic strengthening comes in.
Column & superstructure strengthening
Enhancing columns and superstructures with advanced materials to improve load-bearing capacity and seismic resilience.
Floor diaphragms
Strengthening floor diaphragms to distribute seismic forces effectively, improving the overall stability of the building.
Drag beam strengthening
Reinforcing drag beams to transfer seismic loads between structural elements, enhancing the building’s earthquake resistance.
Fibre Reinforced Polymer (FRP) wrap
Applying Fibre Reinforced Polymer (FRP) wraps to columns and beams, providing additional strength and flexibility during earthquakes.
Shotcrete shear wall strengthening
Using shotcrete to strengthen shear walls, improving their ability to withstand lateral seismic forces. Either dry or wet spray techniques are used depending on the application.
Heritage & landmark buildings
Specialist strengthening for significant structures such as the Christchurch Art Gallery and Christchurch Town Hall, respecting heritage fabric.
