Melbourne House Subsidence

House subsidence is the most common reason for traditional underpinning in Melbourne, an essential process to prevent further sinkage and remedy cracks and damage to flooring and walls. There are different types of underpinning and building subsidence solutions, from cement grout underpinning and concrete underpinning to steel piles and resin injections. 

Regarding house subsidence, the most common causes include high levels of rainfall, cracked pipes, aerated subsoil, tree roots and vegetation, and poor drainage or disconnected downpipes. 

At Raise + Relevel, we have extensive experience in underpinning properties, and we have a variety of solutions available to ensure we address the current problem and prevent future issues from arising.

What is house subsidence?

When the ground beneath a property starts to sink, it pulls the foundation with it, and that is subsidence. The outcome is shifting floors and walls that cause cracks in the structure, which can destabilise the property’s structural integrity. 

It’s a severe problem, and other issues can trigger similar symptoms; it’s important to reach out to a team with a structural engineer to complete a structural assessment to determine whether there are signs of subsidence. It may not be a subsidence issue; it could be a landslip (downward movement), simple settlement, or heave (reverse subsidence). 

In Melbourne, house subsidence is more common than you’d think, and there are signs to look out for, but the cause of subsidence is not always clear.

Signs of house subsidence

Recognising the warning signs of subsidence is crucial for homeowners. Look out for these indicators to address potential structural issues promptly.

Sinking or tilting floors 

Sinking floors indicate subsidence, but you should also be on the lookout for skirting boards separating from the wall and tilting, sinking or sloping floors. 

Cracking walls 

When a building starts to sink, it disrupts the structural integrity, which means cracks in the walls and sometimes the floors. In addition to cracked walls, leaning walls are also a bad sign. 

Doors and windows 

If your doors and windows don’t open and close properly, this could clearly indicate that you have a subsidence issue or something bigger at play. Look out for jammed doors, sticking windows, and misalignments. 

Uneven concrete driveways or patios 

Your driveway or patio can provide you with early notice of home subsidence. If your concrete has raised or lowered spots, you may need a ground engineer. 

Cracks in the foundation or basement walls 

Buildings do crack over time, so a hairline crack isn’t a major cause for concern, but if those gaps are widening or there are large fissures, you should look for further signs of subsidence. 

Water seeping through the basement walls or floor 

Water leaks are a clear indication of a bigger problem, and if water is seeping through the floor or your basement walls, then there is a chance of subsidence. 

If you have noticed any of the signs listed above, contact a licensed builder or underpinning company immediately.

The dangers of house subsidence

Addressing house subsidence is crucial for safeguarding your property and preventing potential collapse. Learn about the risks and take early action to avoid costly damage and insurance complications.

Unstable foundations

These can lead to serious structural damage and safety hazards. If you don’t address house subsidence quickly, there is a long-term risk of severe property damage to the point of potential collapse. A more cost-effective alternative to paying for major repairs is dealing with the issue immediately. 

Damaged property 

Tree roots and certain types of soil can cause subsidence, which means your patios, landscaping, walls, paths, and driveways are prone to damage just as much as your home. 

Subsidence can make it more challenging to sell a property or significantly lower the value of your home. Even for investment purposes, subsidence makes landlords’ insurance more expensive. 

Collapse of a building 

In the most severe cases, subsidence can result in building collapse. Home warranty insurance policies could prevent you from making successful insurance claims if you were aware of a cause for concern (e.g., concrete slabs around your home, including your driveway, have cracks) and didn’t take action. 

If you aren’t sure whether you have subsidence cracks or superficial settlement cracks, call in the professionals to review the cracking and shifting as soon as cracks appear. If there is a subsidence history, building insurance will cost more because a claim is likely.

What can homeowners do to prevent house subsidence?

Sinking concrete can be caused by various issues, from building defects and issues with the building foundation to rising dampness and soil types. For example, reactive clays create weak soil, which can result in unlevel buildings and the need for subsidence repairs. 

Subsidence issues due to soil depend on resin injection underpinning methods because traditional solutions like slab jacking or steel pile underpinning aren’t sufficient.

How can Raise and Relevel help?

We offer a range of solutions to address home or property subsidence issues. Our resin injection method involves filling holes and voids, strengthening your home’s foundation. 

While resin injection is one of our options, we’ll determine the best approach for your needs, whether it’s mass concrete underpinning or another method. This process includes strategically injecting resin into drilled holes to solidify the ground beneath your home, often resolving wall cracks and door or window issues. If needed, we can also perform wall crack repairs.
