Almost all kinds of construction require interior perimeter treating of the foundation except?

In the context of termite treatment for foundations, monolithic slabs refer to a type of foundation where the floor and the footing are poured as a single, continuous slab. This method of construction generally creates a solid, cohesive base that is less conducive to termite entry compared to other types of foundations. Since the monolithic slab itself encompasses the perimeter area without the need for a separate treatment along the interior foundation, it simplifies the termite prevention process.

On the other hand, wooden structures, traditional basements, and floating slabs typically require interior perimeter treatments to effectively manage and mitigate the risk of termite infestations. These types of foundations have more points of potential entry or provide conditions that can support termite activity, hence the necessity for more thorough treatment along the interior.
