What is Slab Heave?


Slab 'heave' is foundation movement caused by the swelling of reactive clay soils as it absorbs water, lifting a building's foundations. When this happens unevenly (eg just one corner or the edges but not the middle) the building's structure is put under excessive strain resulting in cracks and damage. The opposite (subsidence) can also occur as reactive clay shrinks as it dries. 

Building homes on reactive clay soil carries the risk of damage from slab heave & subsidence for years after construction. Houses built during a drought are at increased risk but any significant and uneven change to soil moisture conditions can cause damage, with often complicated diagnosis and tense legal negotiations.


Class action law suits, building tribunal cases and even just general warranty claims can bring significant costs for legal fees, insurance premiums and repairs. Property buy-backs or demolition are not uncommon in severe cases. 

Several Australian Standards & best practice recommendations aim to help reduce the risk of slab heave but there are so many possible causes, parties and variable conditions that determining the root cause (and potentially fault) can be difficult. 

With urban growth pushing volume housing into areas with far from ideal soil conditions, the problem is not going away and home owners often experience what we call The 4Cs of Slab Heave & Subsidence!

The 4Cs
of Slab Heave
& Subsidence


Your home is your castle and also likely your biggest investment. 

Home owners can be justifiably concerned about the damage slab heave or subsidence can cause. 



Technical terms, AUS standards, fine print warranties, multiple trades deflecting blame, obligations you didn't understand or know about. 

Its no wonder home owner is confused. 


Building a home is expensive. Building one to a higher than standard spec is even more expensive.


But fixing a damaged home can potentially cost just as much!


When emotions, liability and money are involved the blame game often kicks in. Disputes can easily escalate to expensive and stressful tribunals or legal action while damage gets worse. 

About SLABsense


SLABsense uses technology & data to reduce the 4Cs for home owners with the following key points of difference:

  • Data based decisions

Traditional residential slab heave monitoring is based on just a few ‘point-in-time’, on site & analogue measurements often taken months apart.


SLABsense captures large volumes of data about a property automatically & electronically (multiple times every day) to add critical context, clarity and a granular timeline enabling more informed decisions. 

  • Focus

Whilst the technology we use is similar to that used in civil engineering & large agriculture the logistics, issues & budgets are very different. 


SLABsense specialises in the residential market, focusing on people and their homes not bridges, tunnels or farms. 

  • Collaboration

SLABsense draws on proven technology from big business and partners with industry specialists to deliver monitoring solutions that are effective and trustworthy yet remain simple & affordable.

  • Customer Experience & Empathy

With lived experience of slab heave & expertise in human-centred design & technology service delivery within Australia’s premier scientific research organisation, SLABsense bridges the gap between home owners, technology & science.
