1. Drilling and injection

2. Trenching and rodding

3. Filling and sealing

4. Raising and levelling

The correct answer is: Trenching and rodding

The treatment method that involves trenching to treat the soil outside of a foundation is trenching and rodding. This method is specifically designed to address concerns related to wood-destroying organisms by targeting the soil where these organisms may reside and pose a risk to the structure. Trenching allows for the removal of contaminated soil or the application of chemical treatments directly into the ground, forming a barrier that helps prevent future infestations. The process typically involves digging a trench around the foundation of the building, which can then be treated with pesticides or other remediation solutions that penetrate the soil effectively. Understanding this method is crucial for professionals conducting wood-destroying organism inspections, as it provides an effective approach to mitigating risks and protecting the integrity of buildings from potential damage caused by pests such as termites.
