What does final grade treatment refer to?

Final grade treatment refers to the application of pesticide or soil treatment methods after the dirt has been graded but before any building construction begins. This stage is crucial as it involves ensuring that the area where the foundation will be laid is properly treated to prevent termite infestations. The grading process modifies the landscape of the site to promote proper drainage, and after this preparation, applying a treatment is essential to protect the structure from potential pest threats.

The timing of this treatment is critical; it occurs when the soil has been leveled and aesthetically prepared (i.e., graded), allowing for an effective application of the chemical barriers or treatments to eliminate existing pests and deter new infestations. It is a preventive step designed to safeguard the integrity of the structure in the long term, particularly against termites that thrive in the soil.
