Why take the risk…. exposed concrete slabs used as a termite visual barrier and it does comply with Australian Standards AS3660.1.2014 as long as the slab is exposed 75mm to be able to inspect for termite leads that can track up the slab edge.
Does this method protect the home?
No, it just provides a visual inspection zone, so termites can be seen “hopefully before any damage occurs” as they travel up the slab edge . Did you know Termites can track up an exposed slab edge overnight and start to damage timbers!!
The below photo details an alternative, where the slab edge still remains exposed 75mm but a secondary physical barrier like Termseal is installed that termites are repelled by. The Termseal product has a chemical impregnated inside called Bifenthrin that helps in the protection of the property. The Termseal barrier installed in the below photo is proven to deter foraging termites. The Termseal Urafen Shield barrier is compressed by the timber frame that will erected by the builder.
Note: Not all Physical Termite barrier installations are the same, always consult a professional Termite accredited installer.
