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

The treatment of soil around a monolithic slab is most effectively accomplished through trenching. This process involves excavating a trench around the foundation of the structure to create an access point for applying chemical treatments. By doing so, the soil can be thoroughly treated with termiticides, which can create a barrier that prevents termites from entering the building.

Trenching allows for a more targeted application of the treatment, ensuring that the chemicals penetrate deeply into the soil where termites are likely to establish their colonies. This method is particularly effective for managing potential termite infestations in and around slab foundations, as it directly addresses the soil that supports the structure while minimizing exposure to areas where the treatment is not needed.

While other options like drilling and injecting can also be used in termite treatments, they may not provide the comprehensive coverage around the foundation in the way that trenching does. Soaking typically refers to saturating a large area with a liquid treatment, which is generally less effective and less precise than applying it directly into a trench. Hence, trenching is recognized as the most effective method for ensuring adequate protection against termites around a monolithic slab.
