Termites And Cracked Slabs

Can termites enter your house through cracks in your concrete slab?

According to research by the Cement and Concrete Association of Australia, a concrete slab designed and built in accordance with our current footing and slab standard AS2870 should keep termites out.

According to the CCAA data sheet, termites can’t get through cracks less than 1.4mm wide. Even though termites are smaller than that, they don’t like the rough concrete edges and have to mud line the crack to make it through.

So if your house slab is designed by a structural engineer to comply with AS2870, the Australian code for residential footings and slabs, then termites should not be able to enter your house through cracks in the slab.
