What is the purpose of pretreatment in construction?

The purpose of pretreatment in construction is to apply preventative measures to the soil and foundational structures before any significant construction begins, specifically before the foundation is poured. This step is crucial in controlling termite infestations and ensuring that the structure will be less likely to become infested in the future. By treating the soil before the foundation is laid, the applied chemical barriers can effectively deter termites from entering the building.

This proactive approach helps in establishing a protective barrier that can significantly reduce the risk of termite damage, which can be incredibly costly and damaging over time. Other options, while they may involve treatment, do not align with the concept of pretreatment as they occur too late in the construction process to prevent early infestation issues.
