How leaking water pipes can wreak havoc on a home’s foundations
Cracked pipes, blocked gutters and broken sewer lines are a surprisingly common cause of the foundation issues that can affect properties.

The sinkhole phenomenon – what causes them and how are they remediated?
When it comes to ground issues, sinkholes can appear suddenly, often with dramatic and serious consequences. While the ground may seem to unexpectedly collapse, the reality is that sinkholes generally develop over a period of time until the ground above simply loses support and gives way, leaving a gaping hole. Understanding what causes sinkholes Sinkholes
The value of ground strengthening for redevelopments in seismic prone areas
The devastation caused by seismic events in New Zealand, including the significant 2010 and 2011 Canterbury earthquake sequence, has seen growing awareness about the interaction between building structures and soil during an earthquake. The challenge for home owners and developers undertaking earthquake strengthening works is to consider both ground strength and building behaviour so that
How extreme weather can affect your home’s foundations
Extreme weather events, natural disasters and extended dry spells have a significant impact on the ground and subsequently, on building foundations. Summer 2018/19 was the third-warmest ever recorded in Australia, and the hot weather pattern has continued, with January one of the hottest on record across both Australia and New Zealand.

A fundamental reason for this movement is often due to changes in the ground under your home’s footings. Many homes experience foundation movement due
Protecting critical infrastructure from the ground up
How ground improvement can deliver long-term resilience to earthquake prone infrastructure How can you make an earthquake-prone structure more resilient? This was the question posed recently by operators of a waste water treatment plant in Wellington, New Zealand, as they sought proactive measures to protect the asset following the introduction of The Building (Earthquake-prone Buildings)
When is sonic drilling the right solution?
Geotechnical engineers often specify the use of deep drilling to assess soil conditions before commencing complex construction projects. Choosing the right drilling method is one of the most important decisions and can directly impact project outcomes.
Transport infrastructure maintenance solutions
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.
