What characteristic of foams enables them to dispense uniformly under slabs?

Foams possess a unique characteristic of being less dense than liquid termicides, which allows them to effectively fill spaces and penetrate areas that may be difficult for liquids to reach. Because of their lower density, foams can expand and take up volume in cracks, voids, and under slabs, creating a more uniform distribution compared to heavier liquid formulations. This property ensures that the foam can navigate and settle into the irregularities of the substrate, providing comprehensive coverage for termite treatments.

The ability of foams to expand and provide consistent coverage without heavy liquid being used is crucial in applications like sub-slab treatments, where achieving uniform dispersion is vital for effective termite control.
