It is essential for a termite treater to understand and know what slab they are treating. Floating slabs are concrete slabs with a deepened and reinforced perimeter. This type of foundation is called a floating slab because it floats on the soil. They are used as foundations for home, businesses, sheds, car garages, additions etc.
Post tension slabs give the best protection from my point of view, cables are run throughout concrete and tightened up. Concrete is less likely to crack and allow termites to enter.
