Soil Heave Protected Slabs


When you build using a PolyVoid designed concrete slab, you can enjoy the peace of mind of having the best possible concrete slab available on the Australian market. Furthermore, it is suitable for most soil types and application whereby concrete is an affordable method of construction.


Concrete slabs can move with the ever changing conditions of your soil, and in particular, its moisture content. A PolyVoid designed concrete slab allows heave and shrinkage of the underlying soil without significant, if any damage to your slab.


Your slab will be better able to avoid potential damage from drainage issues, either from within your property or those caused by neighbouring developments. You can also be comfortable that most homeowner work and landscaping carried out, can be done with much less risk to the structural integrity of the house's footing system. These may include the planting of trees and gardens close to the slab, watering systems, swimming pools and other alterations and additions.  


The diagram below is a basic representation of how the PolyVoid works by compressing under the upwards forces that occur beneath the slab.
