Ground Instability

Addressing wall cracks: know your soil types

Cracks are very common, particularly in houses that are more than 20 years’ old. Although many people can see cracks in their walls, they don’t know why the cracks are there. Wall cracks develop over time as a home’s foundations move.

Engineers and councils urged to rethink emergency storm repair methods

Following the wild storms that have lashed the eastern seaboard, we at Mainmark are urging councils, engineers, builders and insurers to think outside the box as remediation works begin. Large washouts have created serious ground problems, including coastal erosion, flooding and sinkholes.


Is this the reason machinery is malfunctioning?

Machinery malfunction on a mining or construction site is often attributed to poor quality or shoddy equipment, when in fact the problem may be due to ground subsidence. The minor variances in ground level as a result of subsidence can cause machinery parts to misalign, placing unnecessary stress on the equipment.

Why do foundations sink?

Why do foundations sink?

If you’ve spotted large cracks in the walls of your home or gaps appearing between the skirting and floors, there may be a chance the building and the ground beneath it are sinking. Working with a qualified structural engineer to understand the causes of subsidence (the technical term for sinking) is usually the first step

What’s the difference between concrete underpinning and resin injection?

Cracks in the walls near windows and doorways, or sinking and sloping floors, may be early indicators that you are experiencing problems with your home’s foundations. Underpinning can help to address this building issue, which can occur when soil becomes too wet or dry, affecting the foundation structure.

When should you worry about cracks in your walls?

When should you worry about cracks in your walls?

Turning a blind eye to wall cracks in your home may mean you’re missing the warning signs for serious and ongoing structural damage. Wall cracks are common in Australian and New Zealand houses and though some are nothing to worry about, others can indicate a sinking or damaged foundation.
