What is the process for treating the soil around a monolithic slab?

The process for treating the soil around a monolithic slab is trenching. This approach typically involves digging a trench around the perimeter of the slab to allow pesticide or other treatment methods to reach potential entry points for pests, such as moisture-wicking or other structural vulnerabilities. Trenching is essential for creating a barrier and ensuring that the treatment is effectively applied at the right depth and location, thus preventing pest infestation.

Sealing is not suitable for this situation since it involves closing off gaps or cracks in structures rather than treating the soil. Excavation, while related to digging, implies a more extensive removal of soil and is generally not necessary for pest control in this context. Grading refers to leveling or sloping the soil and does not focus specifically on pest control measures around a foundation or slab. Therefore, trenching is the most appropriate method for addressing soil treatment in relation to a monolithic slab.
