Wet weather and soggy, muddy conditions are often blamed as the primary culprit for structural issues in our homes. However, the truth is that prolonged dry periods can be just as harmful to the stability of our foundations.

According to civil engineer and Mainmark business development manager James O’Grady, extended dry spells have a significant impact on the ground and subsequently, on building foundations.

James O’ Grady from Mainmark shares some interesting insights into ground movement and the effects of subsidence on homes and buildings.

Queensland’s Gold Coast is known for its surf beaches, elaborate inland canals and waterways. Revetment walls are a common feature in the region, playing an important role protecting the boundaries of waterfront properties from the effects of erosion that can occur as a result of tidal movements and boating activity.

With thousands of communities across Australia situated in areas with hills, slopes and embankments, home hunters relish the idea of living in a home taking in stunning views and natural light.

There are currently billions of dollars being invested into infrastructure projects to help drive the economy out of a post-pandemic slump. However, while a flurry of new civil construction works will fuel growth, boosting jobs and productivity, it is equally important to service and maintain existing assets that provide essential service for Australian communities.

Australia and New Zealand are lands of diverse topography, with thousands of communities situated in areas where hills, slopes, embankments and elevations are prevalent. And while that may mean stunning views and natural light for those wishing to live on an elevated site, it raises significant challenges for builders and engineers who must consider the ground terrain and other geotechnical issues.

Water supply systems such as damns, tanks and sewage treatment plants provide essential services for Australian communities. And while these marvels of engineering undertake important functions, we must also acknowledge that their quality and longevity play a vital role in maintaining the comforts of modern society. It is why specialised resins, gels and coatings for asset preservation can be just as important – if not more – as the water infrastructure they serve.

As $45 billion worth of infrastructure projects take place over the next five years, smarter solutions will be needed to keep these projects on track and within budget.

PURCHASING and maintaining a property is, for many,
the biggest investment of their lifetime and for homeowners
looking to sell their property, structural defects caused by
ground subsidence can significantly reduce the final sale price
of this investment.

With almost 50,000kms of coastline and more than 10,000 beaches around Australia, it’s only natural that many Australians choose to live by the ocean. Yet, despite the lifestyle benefits of coastal living, construction methods near a shoreline typically need more careful consideration to account for the loose, sandy soil conditions prevalent in these areas.

While much of Australia was forced into shutdown at the height of the coronavirus pandemic, the infrastructure construction industry carried on as the Government acknowledged the sector as an essential service.
