Termites cannot eat through solid concrete. To enter a structure, they must come up around the outside edges or enter through some other opening in the slab. Traditional termite treatments require the application of a continuous chemical barrier to the soil around all possible entry points.
To treat a stress crack, holes must be drilled through the slab along the fault line. If the crack is visible, then treatment may be performed with much greater efficiency. If the crack is hidden beneath floor coverings, then the pest control operator can only guess about the path of the crack.
Liquid treatments can be augmented with foam injections to help provide total coverage.
