Unstable ground can lead to structural issues with a building, affecting worker safety and business operations.
Some of the signs of unstable ground include sloping and sinking floors, and cracks in transport yard pavements and driveways.

New Zealand is no stranger to seismic activity and Christchurch residents know only too well the importance of structural integrity. Widespread liquefaction has affected countless building foundations in the region, including the Kamahi Apartments, an eight-storey residential apartment building in Merivale.

Mainmark: The community relies heavily on a network of roads, bridges, tunnels, railways, ports, airports and public transport. However, as Australia and New Zealand’s populations soar, these assets will come under increasing pressure, requiring an innovative and efficient approach to maintenance and remediation.

Mainmark: Local councils and government departments are responsible for a significant range of assets, from roads, bridges and footpaths, to water, sewerage, and drainage. Ensuring they remain in good working condition to service the public safely, efficiently and without failure is essential. Ongoing monitoring and maintenance of infrastructure is crucial, not only to ensure operational efficiency and safety, but to also preserve the asset’s longevity well into the future.

Although buildings might appear to be static structures, they are constantly moving, affected by even the minutest vibration of someone walking past. What if we could record these vibrations to develop a detailed structural analysis of a building?

Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build.

Mainmark’s UK team has done a great job remediating this London home suffering significant cracking due to subsidence. Thanks to renowned property expert and TV presenter Sarah Beeny for filming and sharing this project.

Mainmark has a wealth of exprience in its team, including Dr Phil Irwin, Area Manager for Victoria and Tasmania, who has a PhD in Earth Sciences and is a qualified geologist.

Mainmark: With unique climates and landscapes, homes in Australia and New Zealand face diverse ground conditions that can cause subsidence, affect building foundations and result in structural issues. While most issues are due to unstable ground, extreme weather conditions including drought and floods can be common contributors to subsidence. Other factors such as leaking pipes or inferior concrete foundations can also be a cause.

Mainmark: Last year, Mainmark announced it was among only a handful of organisations in our industry to hold a 2015 ISO certification for Environmental Management and Quality Management. This is a significant achievement and demonstrates Mainmark’s commitment to complying not only with Australian Standards, but also those recognised internationally.

Mainmark recently delivered an engineered solution to solve a sinkhole problem in Sydney.
