Concrete slabs - A termite barrier

Concrete slabs form part of the termite barrier. However, termites may be able to access timber framing at the edges of the slab, around service pipes and box-outs for plumbing fixtures or through naturally occurring cracks in the concrete.

The majority of termite infestations occur at the perimeter of the building. Leaving an exposed edge to the perimeter of a concrete slab allows easy detection of the presence of termites.
